Hi all,

thankfully, issues https://bugs.eclipse.org/bugs/show_bug.cgi?id=429704 and https://bugs.eclipse.org/bugs/show_bug.cgi?id=429703 seem to be fixed.
I haven’t seen https://bugs.eclipse.org/bugs/show_bug.cgi?id=419475 in action, but I assume it is also fixed. We are slowly getting there.

I have encountered two further issues.

1. The QE exhibits a (short) UI freeze when edit-saving EIQs that have been loaded. On a Mac, this is indicated by a beachball. What are we running on the UI thread that can take a long time to complete?

2. While playing with Viewers, I noticed that a typo in the “label” parameter can lead to a deep exception as follows:

!ENTRY org.eclipse.core.databinding.observable 4 2 2014-03-06 21:03:52.970
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.core.databinding.observable".

Is this normal? Shouldn’t this be caught by a validator much earlier?

Another variant of probably the same issue:
