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!!!!

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.
