[SOLVED] Workflow without a document?!

decoy — Mon, 09 Mar 2009 12:37:22 GMT

Hi, I am a bit new with Alfresco and I have a question about Alfresco workflows. I managed to make advanced workflow using jBPM and i made a custom screen for every node of my workflow. That all works fine for me. Now I would like to start a workflow without a document. What I mean is that a user c

1/ Starting advanced workflow does not attach any document to the process

Solution : have a look at the webclient-config-workflow-actions.xml
See the param tag I commented.

Write it in your webclient-config-custom.xml


   <actions>
         <action id="start_workflow">
            <label-id>start_workflow</label-id>
            <image>/images/icons/new_workflow.gif</image>
            <evaluator>org.alfresco.web.action.evaluator.StartWorkflowEvaluator</evaluator>
            <action>wizard:startWorkflow</action>
            <action-listener>#{WizardManager.setupParameters}</action-listener>
            <params>
            <!–   <param name="item-to-workflow">#{actionContext.id}</param>  –>
            </params>
         </action>
‍‍‍‍‍‍‍‍‍‍‍‍‍

In this very webclient-config-custom.xml, you will find how to place the icon (of this action) wherever you want.

2/ Create the document programmatically

In order to do that, You will surely have to override the StartWorkflowAction.java, get a look at the foundation services in order to create and manipulate documents.

If you wish to, let's keep this topic alive, because I'll soon have to achieve the same thing :
1/ Bypass the first step of the workflow wizard : the type of workflow will have to be automatically selected, depending on the type of document that triggered the action
2/ Have this workflow's package hold no document at first
3/ Create and manipulate a new document that will be attached to the process

Actually I am now on phase 3/ and currently I have a problem how to attach new document to the proccess?!

In my transition i used script sown bellow

<transition to="node1" name="test_transition">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
              <script>
         var dest = companyhome.childByNamePath("User Homes");
               var file = dest.createFile("file_name");
               file.save();
            </script>
           </action>
</transition>

How can I attach my new created file to the process?

You have to add it to the bpmackage

Maybe this will work :

bpm_package.children[0] = file;

try that one :


      <transition name="" to="end1">
         <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
            <script>
               <variable name="bpm_package" access="read, write" />
               <expression>
                  var dest = companyhome.childByNamePath("User Homes");
var file = dest.createFile("file_name");
file.save();     
bpm_package.children[0]=file;   
               </expression>   
            </script>
         </action>
      </transition>
   
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

And add this line to the end of your log4j.properties file

log4j.logger.org.alfresco.repo.jscript=debug

I found solution for my problem. The solution is in script bellow

   <script>
                         var dest = companyhome.childByNamePath("User Homes");
                  var file = dest.createFile("file_name.txt");
                  file.content="test content";
                  file.save();
                  bpm_package.addNode(file);
            </script>
