tmpProposedStartTime_Actual – Wrong datatype

Got a phone call from one of my users. He told me that he is not able to accept an ivitation for a meeting. Instead the following error message occurs when he tries to open the document from his inbox.

I searched the KnowledgeBase but could not find any hint, how to solve the problem. If you google for “tmpProposedStartTime_Actual” you only get two hits.

tmpProposedStartTime_Actual is a computed for display field on the (Notice) form.

The field formula references to some fields starting with “new”. I opened the document with ScanEZ and found that none of these fields contain any value ( for whatever reason ).

I deleted the fields from the document and the user was able to open the invitation.
