Update Workflow Process Instance

Hi,

I'm working on updating an existing Process Instance.

I'm able to fetch the Form Data, Attachment Data, Comment Data.

However the Activity is null when I fetch the Process Instance. Hence I cannot update the Process Instance using UpdateWorkItemData() (if I pass activity 0, I get error - Could not locate specified work).

And when I use UpdateProcessData() I get this error: Comments cannot be updated at the process level. Use UpdateWorkItemData() instead.

Please suggest.

Regards,

Swathi

I'm not sure how you are getting your process instance, I get it by listworkitems() method which returns an array of Class Workitem which has a property ID which is the activity ID updateworkitemdate() wants. I've stripped this out of the DesktopLibrary, hopefully I've get enough detail to see what is going on.

   $tmp = $wf.getType().namespace   $ph = New-Object($tmp + ".pagehandle")   $ph.pagesize=LoadString  $INI_SECTION_OTWS $OTWS_PAGESIZE   $lwfinbox = $wf.listworkitems($ph)   foreach ($lworkitem in $lwfinbox.workitems) {      $date = Get-Date           $wfitems=$wf.getworkitemdetails($lworkitem.ProcessID, $lworkitem.subprocessid, $lworkitem.ID)      foreach ($wfitem in $wfitems.ApplicationData) {           foreach ($wfitem in $wfitems.ApplicationData) {            if ($wfitem.getType().Name -eq "CommentData") {                $wfitem.Comment = "Processed by DesktopLibrary CLI on $date"            }         }         $wf.updateWorkItemData($lworkitem.ProcessID, $lworkitem.subprocessid, $lworkitem.ID, $wfitems.ApplicationData)

</pseudo code>

Hi,

Thank you for the quick response.

I have a process instances in "My Workflow" I fetch them using getListProcessResults(pagehandle) and loop though the process instances. But I was unable to get the activity details in the process instance. That is were I was failing.

As suggested, I used the WorkItems. But I dont get the Form Data for the workitems.

And UpdateWorkData throws this error "Workflow.UpdateWorkData() failed on livelink server. No results were returned."

Sorry, I wasn't necessarily suggesting my method would solve your problem, I only wanted to point out where I got the Activity ID from.

I've not used the getListProcessResults() method before but it appears to provide a pagehandled ProcessInstance[] array. A ProcessInstance class contains within it an ActivityInstance[] array. You should be able to access ProcessInstance.ActivityInstance[0].id (for example), are you saying that array isn't being populated?

Right. The Activity Array is null. When I create the Process Instance and update the form Application Data, Activity array is showing up.

But when I fetch the Process Instances and try to update it, it shows null.
