Answer 1

In my case the problem was that I had called $("#divDialog").removeData(); as part of resetting my forms data within the dialog.

This resulted in me wiping out a data structure named uiDialog which meant that the dialog had to reinitialize.

I replaced .removeData() with more specific deletes and everything started working again.
