Today we found some sort of bug of SharePoint 2010 and / or InfoPath 2010.
When we tried to save an InfoPath form a warning PopUp appeared with the text ‘There has been an error while processing the form’ and with two buttons ‘Try Again’ and ‘Exit Form’.
The even more strange thing is that the error did not appeared on all our computers. On some computers worked just fine.
First we thought that the browser version could be the problem (IE8 and IE9). It was not the case. After a couple of hours my coleague found this post: http://tinyurl.com/ba4ows6, and the problem was solved.
(We just runned this command: regsvr32 “C:\Program Files\Common Files\Microsoft Shared\OFFICE14\htmlchkr.dll”)
I just added this to my list of SharePoint weird things.
