[SOLVED] Workflow without a document?!

[decoy]

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 clicks on a menu item which will say i.e. "Start a workflow" and then i would love to show some screen in which will user insert some additional information like:
- Type of document (predefined)
- Some custom aspects

After insert of this data I need that my workflow create a document (or more documents) and start the workflow for it.

Is it possible and how?! Please if someone have some suggestion let me know.

p.s. I've searched this forum for a while before posting this thread.


Thanks in advance

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;

Hm… This didn't work out for me

[jayjayecl]

any log message?

[decoy]

there is no log message

[jayjayecl]

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

When I used the script above I have following error:
