ES SP2 Upgrade Breaks XML in Submitted Forms

Hi

I've just installed the SP2 upgrade for LC ES - after 5 tries over 2 days...

Now it all *seems* to be working OK - checked version numbers etc - and I can access my processes and forms via Workspace.

However when I try to Submit any Form the server throws a - "com.adobe.idp.taskmanager.dsc.client.task.ActivePrincipalNotFoundExc eption: Assignment to XPath was specified with the following expression: /process_data/formVariable/object/data/xdp/datasets/data/form1/workfl owDetails/nextRecipient, but this expression did not evaluate to anything.

Looking further into this the Form's XML data is there when the form is initially rendered (the PrePopRender 'User Details' are showing correctly), but after the Form is submitted the XML data is not there - hence why my XPath Next User Selection fails.

I've tried setting the Next User Selection to a fixed User ID, but then the WorkFlowState variable setting fails in the Workflow - so the Form XML is definitely totally stuffed :-(

I've tried re-importing the formTemplate and re-setting the Form Data Schema etc - but nothing works.

Has anyone else had a similar issue with ES SP2 and if so got any suggestions for a fix ?

Thanks - Stuart
