I was working with InfoPath 2007 Beta 2 today and needed to have an expression box in a repeating table in the Main DOM display information from the corrsponding row in a repeating section in the secondary DOM and after going through all of the usual steps that I used to go through with InfoPath 2003, I opened up the XPath so that I could manually enter the current() function, and lo and behold it was ALREADY THERE!
This is truly an awesome new feature and it will save me hours upon hours of time for sure! Thank you Microsoft!
