Setting mandatory task properties

Question asked by chrisokelly on Jun 26, 2012

Hi,

I am working on a document expiry workflow that will send a reminder 2 weeks before a documents expiry date, give the option to extend the expiry and, if left till the expiry date, move content to an 'Expired' folder. (see my original post here). the actual behavior is yet to be added, right now I am just trying to test and validate the flow.

The issue I am having is that I have a mandatory property (expiryDate) defined as part of a custom type. I do not wish to have this property set on the start event, but rather the first task after the start event, which will be a pooled task assigned to a group. I gave this task a form key equal to my custom type and set up web-client-config-custom.xml (I haven't set up the share client customizations yet, I am just using alfresco to test so far) to display my property on nodes of that type, with the expectation that the workflow would start, assign a task to the group, I could take the task from the pool and set this property. However, instead, when I attempt to start the task I get a message - A system error happened during the operation: Exception while invoking TaskListener: 05260022 Mandatory task properties have not been provided! {my.company.workflow.root}expiryDate. The start event has no form key and should not require the property (if I correctly understand, which I guess I don't).
Is it required to set any mandatory properties used by any task in the workflow in the start event?

My web-client-config-custom.xml

<config evaluator="node-type" condition="mcwf:submitCorporateDocumentTask" replace="true">
      <property-sheet>
         <show-property name="mcwf:expiryDate" />
   </property-sheet>
   </config>
