Workflow and Document

thomasberment — Fri, 09 Apr 2010 15:55:24 GMT

Hi, I search how it's possible to modify my own document's properties in my workflow.I think it's a script like : <task-node name="review"> <task name="wf:reviewTask" swimlane="reviewer"> <event type="task-create"> <script> docum

you reference the document as "bpm_package.children[0]" and not as "document", try this code it should work :


<task-node name="review">
        <task name="wf:reviewTask" swimlane="reviewer">
            <event type="task-create">
                <script>
               bpm_package.children[0].properties['custom:statutdocument'] = 'En relecture';
               bpm_package.children[0].save;
          </script>
            </event>
        </task>
        <transition name="approve" to="approved" />
        <transition name="reject" to="rejected" />
    </task-node>

Does the property custom:statutdocument actuatlly exist on your document?

Re: Workflow and Document

thomasberment — Mon, 12 Apr 2010 14:41:23 GMT

Yes this property exists …

I tried this code, but I have an other error (03120030 Failed to signal transition 'null' from workflow task 'jbpm$40')

<start-state name="start">
        <task name="wf:submitReviewTask" swimlane="initiator" >
         <event type="task-end">
            <script>
               <variable name="bpm_package" access="read,write" />
               <expression>
                bpm_package.children[0].properties["custom:statutdocument"] = "En relecture";
                      bpm_package.children[0].save();
                      </expression>
            </script>
         </event>
      </task>
        <transition name="" to="review" />
    </start-state>‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hey, I tested this code and it works …

But what is the difference with my other code ?

<start-state name="start">
        <task name="wf:submitReviewTask" swimlane="initiator"/>
         <transition name="" to="review">
           <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
               <script>
                  <variable name="bpm_package" access="read" />
                  <expression>
                     bpm_package.children[0].properties["custom:statutdocument"] = "En relecture";
                       bpm_package.children[0].save();
                     </expression>
               </script>
            </action>
         </transition>   
    </start-state>‍‍‍‍‍‍‍‍‍‍‍‍‍‍

There are many differences but we could start with the first script being BeanShell and the second being AlfrescoScript.

But what is the difference with my other code ?

It appears as though the <script> code prefers to be inside an <action> tag where class is AlfrescoJavaScript due to the fact that we are setting properties. Otherwise you would use:
<event type="quelque-chose">
<script>…

Thx for your reply …

I have an other question, is it possible to stop a workflow before it starts ?
I just want put a condition on the running workflow. And if the condition isn't validate, the workflow stops.

In a script in my "strat state" is a wrong idea because my workflow will start. But I think that it's possible to put a condition in the jsp page, on the list of workflow … ?

If you have an idea …

If you throw an exception from your start task then a workflow instance will not have started. The workflow only exists after completion of the start task.

Or you are correct you can put a guard condition before calling the workflow either on your jsp page or you control code. Or you can start the workflow but only progress once you have all the relevant information. The choice is yours.

Can you explain me, how put a condition in my start-state ?

I find anything for cancelled my workflow …

<start-state name="start">
        <task name="wf:submitReviewTask" swimlane="initiator"/>
         <transition name="inReview" to="node1">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
               <script>
                  <variable name="bpm_package" access="read" />
                  <expression>
                       if(bpm_package.children[0].properties["custom:statutdocument"] != "Travail")
                       {
                          ?END?
                       }
                       else
                       {
                        bpm_package.children[0].properties["custom:statutdocument"] = "En relecture";
                        bpm_package.children[0].save();
                     }
                  </expression>
               </script>
            </action>
         </transition>
    </start-state>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi, to do a condition to run my workflow, I have this code :

<exception-handler>
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
         <script>
            <variable name="bpm_package" access="read" />
                <expression>
                   bpm_package.children[0].properties["custom:statutdocument"] != "Travail";
                </expression>
            </script>
      </action>      
   </exception-handler>‍‍‍‍‍‍‍‍‍‍

But, it dosen't work …
Have you an idea or a tutorial for me ?
Thx.

thomasberment — Mon, 19 Apr 2010 12:41:58 GMT

I changed my code for this :

<start-state name="start">
        <task name="wf:submitReviewTask" swimlane="initiator"/>
         <transition name="inReview" to="condition">
            <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
               <script>
                  <variable name="bpm_package" access="read" />
                  <variable name="statutDoc" access="read,write" />
                      <expression>
                         statutDoc = bpm_package.children[0].properties["custom:statutdocument"];

                      </expression>
                  </script>
            </action>
         </transition>
    </start-state>
    
    <decision name="condition">
      <transition name="conditionOK" to="sendMail">
         <condition>
            #{statutDoc == "Travail"}
         </condition>
      </transition>
      <transition name="conditionKO"  to="end">
         <condition>
            #{statutDoc != "Travail"}
         </condition>
      </transition>
   </decision>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And it works !
