Changes from 0.94.1 to 0.94.2
06-Jun-2003
-----------------------------
- Velocity 1.3+ is required to rebuild ActionServlet sources (ActionServlet
  remains compatible with Velocity 1.1+)
- application attribute named "javax.servlet.ServletContex" is set on servlet 
  startup for Velocity 1.3+ (enables WebappLoader velocity tool usage)
- relative and absolute paths can be now used together with Velocity for
  'file.resource.loader.path' and 'runtime.log' Velocity properties - absolute
  paths must start with slash ('/') or have Windows format ('C:\...'); 
  this is a small incompatibility with previous releases!
- retrieval of type handlers is now faster thanks to caching
- bugfix: ActionConfig could not be loaded from unexpanded .war file
- changes in examples:
  - removed leading slash from relative template paths in Velocity.properties


Changes from 0.94 to 0.94.1
21-Apr-2003
---------------------------
- bugfix: <input-variable> with false 'if' condition overrided value with null
- bugfix: <input-variable> direct 'value' now recognizes all numeric types
- bugfix: standard type handlers now deal with widening conversions from wrapper
          classes to primitive types (Byte -> short, Long -> float etc.)
- bugfix: ActionConfig with no <components> caused NullPointerException
- added note about Velocity.properties to the Section 2. of Specification
- new links added to "Related projects"


Changes from 0.94beta2 to 0.94
15-Feb-2003
------------------------------
- ActionServlet_0_94beta2.dtd -> ActionServlet_0_94.dtd
- added a new Validate example


Changes from 0.94beta to 0.94beta2
28-Jan-2003
----------------------------------
- ActionServlet_0_94beta.dtd -> ActionServlet_0_94beta2.dtd
- two more $variable is put into Context before ActionServlet.handle(): $AC
  (of type ActionServlet) and $REQUEST_TYPE, which contains request type
  (http.get, http.post, ...) and one $variable is put into Context in handle(): 
  $ACTION_NAME, which contains the name of <action> 
- added ActionServlet.getClassLoader() method - useful for custom classloading
- special *unassigned* name may be used for <action> that will handle all
  unassigned actions (note: ActionServlet.unassignedAction() still works)
- <include-template> 'name' attribute is now evalutated as an expression
- <on-return>s may be nested also in <components> (after the last <component>
  element), i.e. <on-return>s common to all components may be defined
- <on-exception>s may be nested also in <template> and <templates> (as their 
  last subelements), i.e. <on-exception>s for one <template> or all <templates>
  may be defined (propagation works: <template> -> <templates>' <on-exception>s)
- added new internal classes Expression, VelocityExpression, WMExpression
  to org.actionframework.engines and its subpackages
- removed internal ContextParameterRetriever class
- Context is now searched first - when retrieving parameters from the request
- <on-return>s of <components>/<component> are now searched only for <action>s
- build.xml creates 'classes' folders in examples (useful if building from CVS)
- ActionConfig may now refer to external entities - this is useful for dividing 
  it into several parts instead of one big XML file (note: some XML parsers, 
  such as JAXP 1.0, do not support external entities properly, but it's ok with
  JDK1.4's parser, for example)
- Sun JAXP 1.0 XML parser has been replaced by Xerces 2.2.1 (sup. ext. entities)
- registered default type handlers for wrapper classes of primitive types
- small improvements in log messages (<in/output-variables, <on-return>s, 
  <on-exception>s - including retrhrowing info, ...)
- small changes and fixes in the API documentation and Specification 
- bugfix: <input-variable> could be processed twice if contained a composite 
          type definition (InputVariableParameterRetriever does only check now)
          and was not evaluated for some conditions (both bugs from 0.94beta)
- bugfix: check for new-session template didn't work if ActionServlet was not
          subclassed
- bugfix: <include-template> throwed NullPointerException w/o 'if' condition
- bugfix: all HTTP parameters are put into Context before standard $variables
          are set (if org.actionframework.ActionServlet.passAllHttpParams 
          property is true), so that values like $SERVLET are set properly
          (this could have led to a security issue in certain cases)
- bugfix: <pre/post-invoke>, <validate> didn't work with 'component' attribute
- bugfix: <on-return>s processing for <pre/post-invoke>s malfunctioned
- bugfix: ConversionException could not be processed by <on-exception>s as 
          declared in 0.94beta
- bugfix: runtime was not reinitialized properly when ActionConfig changed (if
          org.actionframework.reloadActionConfig <property> was set to true)
- bugfix: ActionServlet.error() didn't filter special HTML chars for stacktrace
- bugfix: errors in <validate> and <pre/post-invoke> elements were reported 
          as errors in <invoke>
- bugfix: value of org.actionframework.ActionServlet.maxFileSize <property> was
          ignored if org.actionframework.ActionServlet.uploadDir was also used
- bugfix: recursive calls of invalidate() in ActionRuntime.destroySession()
          are now prevented (crashed some JVMs)
- bugfix: processing of <on-exception>s didn't correspond to beta Specification
- bugfix: lib/ActionServlet.jar didn't include BaseCompositeTypeHandler class
- changes in examples:
  - as_examples.war does not contain XML parser (caused problem with Tomcat 4.1)
  - Chat:
    - chat.ChatServlet code moved to ActionConfig
  - DateHandler:
    - handler now extends BaseCompositeTypeHandler (simpler code)
    - <on-exception> is used to handle wrong parameters
  - FileUploads:
    - ActionConfig uses <on-exception> nested in <components>
    - FileUploadsServlet code was also replaced by <on-exception> element
  - GuestBook:
    - GuestBookServlet code was replaced by <on-exception> element
  - Shop: 
    - components use a new JDBC design pattern (see shop.sql package)
    - ActionConfig size reduced by 75 lines and uses new <validate>, 
      <include-template> and <pre-invoke> elements
    - custom exceptions are used in favour of old-style error codes
    - shop.ShopServlet.invokeMethod(), conversionError() and onException() 
      replaced by <pre-invoke> and <on-exception> elements in ActionConfig
 - TwoForms:
    -  ActionConfig catches ConversionExceptions by <on-exception> element


Changes from 0.93.2c to 0.94beta
29-Dec-2002
--------------------------------
- ActionServlet_0_93.dtd -> ActionServlet_0_94beta.dtd
- preferred XML DOCTYPE path is now "http://www.actionframework.org/dtd/..."
- removed deprecated field ActionServlet.sessionReaperTimeout
- removed "final" from engine.* classes (prevented engines subclassing)
- added ActionServlet.getContext() method - returns current request's context
- added ActionServlet.requestCleanup() method - called after request is finished
- added ActionServlet.destroyComponent() method - allows component destroying
- ActionServlet.getComponent() passes new Context (instead of null) to "static" 
  components created during initialization (in start() method, for example)
- if Template.getName() returns pathname, slash (/) is always used as separator
- added ActionServlet.getTypeHandler() method - accesses global type handlers
- added EvaluationException - used with <in/output-vaiable>s and 'if' conditions
- added <pre-invoke>, <post-invoke> (allow additional before/after actions),
  <include-template> (allows nesting of templates) and <validate> element 
  (allows validation of converted parameters) - see Specification for details
- <on-exception>s may be nested also in <components> (after the last <component>
  element), i.e. <on-exception>s common to all components may be defined
- <on-exception> has a new optional attribute "rethrow-if", which allows to
  propagate the handled exception (rethrow-if is evaluated at the end of
  <on-exception> processing, i.e. after its <invoke>s, <output-variable>s etc.)
- exceptions are now also propagated to parent <action>/<invoke> (if any)
- <property> element may now contain <input-variable>s -> any type of properties
  can be set; ActionServlet.getProperty() return type changed to Object
- added new org.actionframework.ActionServlet.printStackTrace property - if 
  true (default), ActionServlet.error() method will print exceptions' stacktrace
- added org.actionframework.ActionServlet.imageInputToBoolean <property> - if
  true, value of "foo" parameter from the request would be retreived as "true"
  from <input type="image" name="foo"> (sent as "foo.x=0&foo.y=0" by browser)
- added org.actionframework.ActionServlet.passAllHttpParams <property> - if
  true, all HTTP parameters will be put into Context automatically
- <input-variable>s are now evaluated in the specified order - in all elements!
- arbitrary order of <output-variable>s and <invoke>s is now allowed inside
  <on-return>, <on-exception> and <template>
- <template> names may now contain regexps (like ".*"), so that <invoke>s and
  <output-variable>s can be set for several templates in one place
- ActionServlet.invokeMethod() may now throw any exception
- ConversionException may be now also processed by <on-exception> elements
- added getCause() and initCause() methods to AFWException, AFWRuntimeException 
  to make all exceptions compatible with JDK 1.4+'s java.lang.Throwable class
- added setContext() method to internal classes WMContext and VelocityContext
- ActionServlet.getComponent() now returns Class object for "static" components
- major code cleanup of ActionServlet.java and Action.java
- many internal classes moved to new org.actionframework.runtime package,
  added ActionRequestData, ExceptionHandler, PostElements, TemplateElements
  and IncludeTemplateData classes
- access modifier of beforeConversion(), beforeInvoke(), invokeMethod(), 
  afterInvoke(), conversionError(), unassignedAction() and stop() methods of 
  ActionServlet changed protected -> public (mostly consequential of refactor.)
- added optional 'type' attribute in <action> element to allow action selection 
  based on the type of request (http.get, http.post, ...) -> this required also 
  changes in ActionServlet methods that had 'form' parameter (beforeInvoke(), 
  afterInvoke(), invokeMethod(), beforeConversion(), conversionError(), 
  getActionMethod(), unassignedAction()), onException() and onReturn()) - ex.:

  beforeInvoke(Context context, String form, String action, Object[] params)
  // has changed to:
  beforeInvoke(Context context, String reqType, String action, Object[] params)

  Note: Values of 'form' and 'action' are concatenated by '.':
        a) form="form1", action="submit" -> action="form1.submit"
        b) no form, action="submit" -> action="submit"
- if HTTP parameter is missing and target action method parameter is array,
  empty String[] array is passed to the method
- $RESPONSE (HttpServletRequest) and $REQUEST (HttpServletResponse) variables 
  are now set before ActionServlet.handle()
- Specification updated, small API clarifications made
- new links added to "Related projects"
- bugfix: "request" components are now destroy()-ed at the end of request
- bugfix: template's <output-variable>s and <invoke> could be processed more
          than once under some conditions
- changes in examples:
  - method calls servlet.getProperty(...) -> servlet.getProperty(...).toString()
  - access moddifiers of previously protected methods in ActionServlet 
    subclasses had to be changed to public (GuestBook, Chat, FileUploads, Shop)
  - overridden ActionServlet.invokeMethod() thrown exception had to be changed  
    to Exception (Chat, Shop)

-------------------------------
- Velocity 1.2+ is now needed for rebuilding AS (but still works with Vel. 1.1)
- DefaultInstantiator recognizes component construtor with 3 args (+ Context)

Changes from 0.93.2a to 0.93.2b
13-Aug-2002

- log messages now include [init], [cleanup] or [request id] prefix (request 
  id is taken from Context.hashCode() and may be "unknown" if cannot be 
  determined - for log messages comming from non-request thread, for example)
  note: applications need not to prepend [request id] to log messages, internal
        thread-to-context mapping is used to manage prefixes automatically
- $SERVLET and $URL variables are now set before ActionServlet.handle()
- new org.actionframework.logAllTypeHandlers <property> may be set to "true"
  to log invocation of all type handlers (by default org.actionframework.* 
  type handlers are excluded from the log)
- trailing slash in a new-session URL no longer causes unassigned action '/'
- added new RedirectTemplate class - virtual template for URL redirecting from
  methods with Template ret. type - see ActionServlet.getTemplate() in API doc
- bugfix: misleading unexpected initialization error was reported when 
          ActionConfig was not found

- bugfix: parameter retreiving didn't work for <invoke> in some cases
- bugfix: show-* attribute ignoring didn't work for nested <invoke> elements
- bugfix: composite type definition was not checked against null
- bugfix: if no <template> set 'is-new-session' attribute to "true" and
          newSession() returned null, NullPointerException was thrown
- bugfix: if show-value-of returns a template and there is no content type
          handler found, the template is rendered as usually
- bugfix: array values had additional pair of brackets [] in log messages
- bugfix: ConversionException.setParameterValue() was not called in some cases
- changes in examples:
  - build.xml now detects classpath for any version of Velocity automatically,
    copying of velocity*.jar files to Ant's lib directory is not required
  - bugfix: SendReceive demo functionality was broken


Changes from 0.93.2 to 0.93.2a
6-Jul-2002

- preferred DTD URL is now "http://www.actionframework.org/dtd/..."


Changes from 0.93 to 0.93.1
30-May-2002
---------------------------
- when new org.actionframework.reloadActionConfig <property> is used
  and ActionConfig changes, ActionServlet tries to initialize a new runtime
  first and only on success destroys the old runtime - this ensures
  at least some functionality of webapp if the new runtime cannot be used
- direct String values of <in/output-variable> are now evaluated, so they
  can contain expressions like: value="$URL/some/path/$myVariable"
- if <in/output-variable> specifies component and 'value' attribute equals to 
  "class", the component class is put into context - now works with WebMacro
- reloading of ActionConfig now works also from CLASSPATH
- lib\servlet.jar updated - now contains classes for Servlet 2.3 API
- added Section 1.4.1: "Type handlers and actions" to Specification
