Timer event with time set dynamically based on process instance variables

[snakey]

Hi,

I'm very new to Activiti.  I have a basic process set up in XML with a few tasks and some branching, along the way setting and reading process instance variables.  I would now like, at some point in the process, to be able to have the process pause and wait until a certain time is reached.  I believe I can do this with a timer event like:

<blockcode>
<timerEventDefinition>
    <timeDate>2011-03-11T12:13:14</timeDate>
</timerEventDefinition>
</blockcode>

However I would like it to get the timeDate setting dynamically from variables on the process instance.  Is there a way to do this with timer event?  Or another way of approaching this requirement?

Any help greatly appreciated, thanks!

Hi,
Yes, it should be possible.
One of our requirement, we were used  execution variable inside the timeEventDefinition. we want to repeat the same process after certain interview, so we have used "R1/PT2M" via execution variable.
Here is code snippet.

<code>

<boundaryEvent id="boundarytimer4" name="Timer" attachedToRef="sid-A9FA5F1E-66A8-4E7B-A6AF-A8105A56BDD4" cancelActivity="false">
      <timerEventDefinition>
        <timeCycle>${dueDateRemainderInterval}</timeCycle>
      </timerEventDefinition>
    </boundaryEvent>
   
   
     <serviceTask id="alfrescoScripttask1" name="Calculate timer cycle " activiti:class="org.alfresco.repo.workflow.activiti.script.AlfrescoScriptDelegate">
      <extensionElements>
        <activiti:field name="script">
          <activiti:string><![CDATA[//
            dueDateRemainderInterval = "R1/PT2M"           
            execution.setVariable('dueDateRemainderInterval',dueDateRemainderInterval);
            ]]></activiti:string>
        </activiti:field>
      </extensionElements>
    </serviceTask>

</code>

In your case, you can try like the below one.
<code>
<timerEventDefinition>
    <timeDate>${dateVariable}</timeDate>
</timerEventDefinition>

</code>

Hope this helps you.
