  • problem with action state


    I have a problem in my file "web-flow.xml", my code is:

    <action-state id="action.RP01.init"> 
            <action bean="RP01ActionRefresh" method="initForm"/>
            <transition on="success" to="action.RP01.refresh"/>  
    <action-state id="action.RP01.refresh">   
          <action bean="RP01ActionRefresh" method="bindAndValidate"/>
          <action bean="RP01ActionRefresh" method="updateTemplate"/>  
           <transition on="success" to="view.RP01"/> 
    why the method "updateTemplate" is not execute?

    Read the javadoc documentation for action state, it should tell you :-)

      I've pasted the javadocs in from the latest revision in CVS:

      * A transitionable state that executes one or more actions when entered.
      * When the action(s) are executed, this state responds to their result(s) to
      * decide to go next.
      * <p>
      * If more than one action is configured, they are executed in an ordered chain
      * until one returns a result event that matches a valid state transition out of
      * this state. This is a form of the Chain of Responsibility (CoR) pattern.
      * <p>
      * The result of an action's execution is treated as a contributing
      * criterion for a state transition. In addition, anything else in the
      * Flow's <code>RequestContext</code> may be tested as part of custom
      * transitional criteria, allowing for sophisticated transition expressions
      * that reason on contextual state.
      * <p>
      * Each action executed by this action state may be provisioned with a set of
      * arbitrary properties. These properties are made available to the action
      * at execution time.
      * <p>
      * Common action execution properties include:
      * <p>
      * <table>
      * <th>Property</th><th>Description</th>
      * <tr><td valign="top">Name</td>
      * <td>The 'name' property is used as a qualifier for action's result event.
      * For example, if an action named <code>myAction</code> returns a <code>success</code>
      * result, a transition for event <code>myAction.success</code> will be searched,
      * and if found, executed. If the action is not named a transition for the base
      * <code>success</code> event will be searched and if found, executed.
      * <br>
      * This is useful in situations where you want to execute actions in an ordered chain as part
      * of one action state, and wish to transition on the result of the last one in the chain.
      * For example:
      * <pre>
      * <action-state id="setupForm"&gt;
      * <action name="setup" bean="myAction" method="setupForm"/&gt;
      * <action name="referenceData" bean="myAction" method="setupReferenceData"/&gt;
      * <transition on="referenceData.success" to="displayForm"/&gt;
      * </action-state&gt;
      * </pre>
      * The above will trigger the execution of the 'setup' action followed by the 'referenceData' action. The
      * flow will then respond to the referenceData 'success' event by transitioning to 'displayForm'.
      * </td>
      * <tr><td valign="top">Method</td>
      * <td>
      * The 'method' property is the name of the method on a <code>{@link org.springframework.webflow.action.MultiAction}</code>
      * implementation to call when this action is executed. The named method must have the signature
      * <code>public Event ${method}(RequestContext)</code>, for example a method property with value
      * <code>setupForm</code> would bind to a method on the MultiAction with the signature:
      * <code>public Event setupForm(RequestContext context)</code>.
      * </td>
      * </tr>
      * </table>
      * @see org.springframework.webflow.Action
      * @see org.springframework.webflow.action.MultiAction
