I have a form that has a comment field that auto populates the commenter when the comment field changes. It is being set to the value held in another form field that gets populated on form load. This rule works fine in Filler and works fine in Browser except when the commenter tabs out of the comment field (ie, they type in the comment and hit tab to go to the next field). When they add their comment and click out of the field instead of tabbing, it populates just fine. To add to all this, it is also itermittent and will sometimes work just fine with tabbing. I have re-added the repeating table to the form and verified that the postback setting on the field is set to Always, but it still exhibits the same behavior. I use InfoPath 2013 and host the form on SharePoint 2013.
Thanks for the help,
Greg
