| [EMF Forms] NPE on display reference model dialog [message #1703939] |

In the EMF Forms View editor I can't display the dialog for creating and
linking reference the reference model to my view model. Pressing on the
button I get the following error (see stack trace below).
This problem occurs on my production Mars Eclipse (many features
installed) on a fresh workspace with only the 3 Makeithappen viewModel
example projects installed.
However, from a newly installed Mars Eclipse Modeling on the same
workspace/projects I can see and get the dialog to display.
So... it looks like some kind of conflict with one or more bundles
running on my production Eclipse and the EMF Forms GUI.
Any ideas - other than starting over with a fresh install?
thanks,
John
