InfoPath Dev

I have a SP list with a custom date field. The date picker works fine with the ootb form but when I modify it in InfoPath and publish back to the SP list, the date picker no longer works. When I select the icon in the debugger it shows 'dateTime1033' is undefined. I'm running SP 2013 enterprise, Infopath 2013 and IE 11. Any suggestions? Thnx

We have this same issue. Did you ever figure out what the problem was?

The issue was that Microsoft released some security patches in March which rendered the date picker and any calculated fields useless. Our fix was to go back to SP2010 and InfoPath 2010... now everything is working like a charm.
