Description Nicolas Bros CLA 2010-10-20 11:47:47 EDT 
I got a ConcurrentModificationException by trying to open the "Load customizations" dialog while a model was being opened in the model browser.

I think the catalog was iterating on the MoDiscoResourceSet when a Resource was added to it, resulting in the ConcurrentModificationException.

Here is a similar ConcurrentMoDificationException but the stack trace is not exactly the same.
I got it with a clean new Helios 3.7M2 with Modisco nightly from 19/10.
The error occurs one time. Not reproductible.
Comment 2 Gregoire Dupe CLA 2011-07-21 08:03:55 EDT 
We will try to solve the query, facet and customization problems by using the
EMF Facet. We then have to wait the next version of the facet feature => P4
Comment 3 Gregoire Dupe CLA 2011-09-28 07:37:48 EDT 
We will switch to EMF Facet before to try to solve such bugs. => P5
