Workflow Timer DueDate issue

aswini

Using an expression for defining due date for creating Timers in Workflow is not working. Any ideas how to use expressions in specifying due date for a timer.

In my processdefinition xml, if I use:

<timer name="sendMail" duedate="#{bpm_workflowDueDate} - 1 business days"> or
<timer name="sendMail" duedate="#{bpm_workflowDueDate} - 1 days">
‍‍‍‍

Error:

Caused by: org.alfresco.service.cmr.workflow.WorkflowException: duedate expression must evaluate to a date‍

Please help!!!!

Regards
Aswini

Maybe you should try to define the date with a script / variable as

<variable name="theDate" access="read,write"/>
      <expression>
         // build your date theDate right here in JS;
      </expression>

So, I tried something like:

<variable name="theDate" access="read,write"/>
      <expression>
         bpm_workflowDueDate + 1;
      </expression>‍‍‍‍

I am still receiving the same error!!

As you see in the following example, your syntax seems not to be correct :

http://wiki.alfresco.com/wiki/Workflow_Reqs_and_Design#Start_Workflow_Action

maybe (although I'm no expert):

var theDate = new Date();
theDate.setDate(bpm_workflowDueDate.getDate() + 1);  // 1 means 1 day

I am posting my processdefinition xml. I am still having issues assigning the Email notification date (theDate) to duedate -1.

<script>

                     theDate.setDate(bpm_workflowDueDate.getDate()-1); or even theDate.setDate(theDate.getDate()-1);
