Workflow Timer DueDate issue

aswini — Tue, 03 Mar 2009 12:59:10 GMT

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="sendM

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>
            <variable name="theDate" access="read,write"/>
                  <expression>
                     var theDate = new Date();
                     theDate.setDate(bpm_workflowDueDate.getDate()-1); or even theDate.setDate(theDate.getDate()-1);
                  </expression>
            </script>
