Client getting a validation error while submitting my form in InfoPath Desktop client, but nothing is being marked with red asterisk.
The 'show details' button tells that required fields were markes with a red asterisk, but there are none on the form.
All the fields are filled and the strangest thing is that this is happening on some clients - the rest of them is working just fine. I've removed the 'required' marks on fields that haven't been present on the form. The client has been already instructed to clear the InfoPath Desktop App Cache folder.
The thing that i didn't try is to clear the server-side as stated in the answer from that question.
How can i debug this kind of a problem, and what does it mean that 'some rules were not applied'
