Problème sur aspect optionnel dans un Workfl avancé [Résolu]

huberd — Tue, 22 Apr 2008 18:41:07 GMT

Bonjour,j'ai défini dans mon workflow la possibilité de définir ou non une liste de relecteurs grâce à l'aspect suivant : <aspects> <aspect name="lwf:reviewAssignees"> <associations> <association name="lwf:reviewAssignees"> <source&g

Lorsque je créé la condition suivante:

      <transition name="" to="startreview">
         <condition>#{lwf_reviewAssignees != null}</condition>
      </transition>      ‍‍‍

dans le noeud de décision suivant :

   <!–**************************–>
   <!–**      <Decision>      **–>
   <!–**     checkreview      **–>
   <!–**************************–>
   <decision name="checkreview">
      <event type="node-enter">
        <action class="lpr.alfresco.repo.workflow.jbpm.WriteInfo">
            <type>Decision</type>
            <name>checkreview</name>
            <disable>false</disable>
        </action>
      </event>
      <transition name="" to="startreview">
         <condition>#{lwf_reviewAssignees != null}</condition>
      </transition>      
      <transition name="" to="startapproval"/>
   </decision>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Dans le cas où je ne choisis aucun relecteur, la condition suivante est tout de même évaluée et retourne vrai.

<condition>#{lwf_reviewAssignees != null}</condition>‍

ce qui fait passé le workflow à l'étape startreview alors qu'elle devrait passer directement à l'étape startapproval. Donc cela me génère le message d'erreur suivant, ce qui est normal vu que l'aspect lwf:reviewAssignees n'a pas été renseigné dans le workflow.

Comment faire pour évaluer correctement la variable lwf_reviewAssignees ou la présence ou absence l'aspect lwf:reviewAssignees dans le workflow courrant.

Merci pour votre aide précieuse.

Bon, j'ai enfin fini par résoudre mon problème. Ma solution vaut ce qu'elle vaut, mais bon si cela interesse quelqu'un…
En faite j'ai écris une petite classe qui me permet de tester si la variable existe ou pas en fonction de son type. Si son type est undefined alors la variable n'existe pas et donc ma classe me retourne false. Dans le cas contraire, elle me retourne true.

package lpr.alfresco.repo.workflow.jbpm;

import org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript;

   public void execute(ExecutionContext executionContext) throws Exception {
      MyLogger.debugln("lpr.alfresco.repo.workflow.jbpm.CheckNull (Start)…",1);
      if (type == null || type.length() == 0) {
            throw new WorkflowException("CheckTypeExist variable name has not been provided");
        }
      
      Boolean result=true; 
      String varStr = var.getTextTrim();
        if (varStr != null && varStr.length() > 0)
        {
            if (varStr.startsWith("#{"))
            {
                String expression = varStr.substring(2, varStr.length() -1);
                expression = "typeof " + expression; 
                //System.out.println("Expression: " + expression);
                Object eval = AlfrescoJavaScript.executeScript(executionContext, services, expression, null);

                if (eval == null) {
