bpm_package in expression

[suleyman]

Hi,

I'm trying to make a simple decision node in a workflow for days. For some reason bpm_package is not defined within expression tag.
This works:

   <decision name="testAction1">
      <event type="node-enter">
          <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
           <script>
             <variable name="ovs_BouwAan" access="read,write" />
             <expression>
             ovs_BouwAan=false; 
              </expression>
           </script>
         </action>    
      </event>   
     <transition name="Actie2" to="DoAction2" />      
      <transition name="Actie1" to="DoAction1"> 
        <condition>#{ovs_BouwAan==true}</condition>
      </transition>     
   </decision>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This one doesn't work (bpm_package not defined error):

   <decision name="testAction1">
      <event type="node-enter">
          <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
           <script>
             <variable name="ovs_BouwAan" access="read,write" />
             <expression>
              var wf_Document = bpm_package.children[0];
              ovs_BouwAan = wf_Document.properties["omgevingsvergunning:bouwvergunning"];
             </expression>
           </script>
         </action>    
      </event>   
     <transition name="Actie2" to="DoAction2" />      
      <transition name="Actie1" to="DoAction1"> 
        <condition>#{ovs_BouwAan==true}</condition>
      </transition>     
   </decision>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Is it even prossible to read a property from a workflow resource document within a decision node? I have tried every possible way. Please help me with this error.

I have changed it to this:

   <decision name="testAction1">
      <event type="node-enter">
          <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
           <script>
             <expression>
              var wf_Document = bpm_package.children[0];
              var wf_Variabele = wf_Document.properties["omgevingsvergunning:bouwvergunning"];
              if (wf_Variabele==true){
               wfBouwAan="1";
              }else {
               wfBouwAan="2";
              }
             </expression>
             <variable name="wfBouwAan" access="write" />
           </script>
         </action>    
      </event>   
     <transition name="Actie2" to="DoAction2" />      
      <transition name="Actie1" to="DoAction1"> 
        <condition>#{wfBouwAan=="1"}</condition>
      </transition>     
   </decision>   ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And it's working. Was it the position of the variable tag?
