Hi We cannot do Smalltalk condenseChanges and this is a showStopper for 1.1 beta. http://code.google.com/p/pharo/issues/detail?id=2367 After some hours of debugging, Lukas has the intuition that this is related to methodTrailer. I did some stupid tests... and apparently the problem occured between 11117 and 11128 If you take 11117 and run Utilities readServerUpdatesThrough: 3922 saveLocally: true updateImage: true and in a 11120 image Smalltalk condenseChanges is working. So the problem is somehow related to methodTrailer. Igor can you have a look?
