Overriding Take Ownership functionality?

[amanjure]

Please see my process definition file.

The idea is I have an article and its submitted to a
1. either single content producer.. or a
2. pool of content producers..

when the user selects to submit it to a pool of content producers.. a particular content producer can "Take Ownership" of the article or assign some other Producer to it.  The assigning part works fine and the workflow is transitioned to the swimlane "singleproducer". what I want is when the content producers press Take Ownership.. I need the workflow to transition to the "singleproducer " swimlane too.. and its not happening currently..it just is stuck there in the same swimlane i.e "multipleproducers"

could anybody suggest me how I can manage to do that? following is my processdef.

thanks in advance

Can I clarify you would like the workflow to automatically move to the next step when the user presses the 'Take Ownership' button.

Normally, the behaviour associated with this action is just to take ownership - i.e. the task will dissappear from the inbox of all others in the pool.

There isn't anyway to simply override this behaviour in the web client - certainly not via the process definition.

[amanjure]

yes you are right.
is there any other way to approach that problem..

i.e in one step.. you wither assign the workflow to a particular person.. and goes to next step.. or assign it to a pool and a person from the pool will assign to himself (or someone else) and then t goes to the next step in the logical flow?

[davidc]

There's a task assign event which can be hooked into within the process definition.

So, perhaps you can use that to automatically trigger the next step.

I suggest taking a look at the jBPM docs as they'll provide exactly how to do that.

[amanjure]

thanks david,

i'll look into it..

Hello

Did you find how to trigger easily an action with the 'Take Ownership' button. ?
If yes, i would be interrested to see how you did it.


Thanks

If yes, i would be interrested to see how you did it.

I also would be interested.  I'm currently playing with the pooled tasks jsp files, and have gotten this far:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<%@ taglib uri="/WEB-INF/alfresco.tld" prefix="a" %>
<%@ taglib uri="/WEB-INF/repo.tld" prefix="r" %>

<f:verbatim><CENTER><FONT SIZE="+3"></f:verbatim>

   <f:verbatim></FONT><BR/><FONT SIZE="+2"></f:verbatim>
   <h:outputText value="In the mean time make sure your tasks are complete." rendered="#{empty WorkflowBean.pooledTasks}" />
   <f:verbatim></FONT></f:verbatim>
   
   <a:actionLink id="get-next-task" value="Get Next Task" image="/images/icons/get-next-job.png" showLink="false"
      actionListener="#{WorkflowBean.setupTaskDialog}" action="dialog:manageTask" rendered="#{not empty WorkflowBean.pooledTasks}" >
      <f:param name="id" value="#{r.id}" />
      <f:param name="type" value="#{r.type}" />
   </a:actionLink>
<f:verbatim></CENTER></f:verbatim>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

but now I can't see which way to go.  Currently I'm thinking of adding some extending the javascript capabilities with some Java (as per http://wiki.alfresco.com/wiki/JavaScript_API#Adding_Custom_Script_APIs and http://wiki.alfresco.com/wiki/Adding_a_Custom_Dialog).  But this seems like a lot of work and overkill.

The ultimate aim is to just have a button which simply allows the user to grab the oldest task.  Rather than the current process which allows them to a) selectively pick jobs (our users tend to pick the easy ones ) and b) then "Take Ownership".

I see a few people have asked this and similar questions.
