Hi , I am still not sure I understand the git based development workflow. I set up my image and repository as described by the guide. now, if new commits are in the pharo-project, iceberg shows the list of incoming changes (commits). Ok, but: If I modify code in my image (for example, change a method in class Morph), the morphic-core package is marked as dirty in monticello and my pharo repository in iceberg is marked with an asterisk. If I choose "synchronize repository ..." I would expect my change to be an uncommited change, but instead, it isn't shown and the Morphic-core package isn't dirty anymore. Is it because I need to create a branch first ? But why is the Morphic-core package not dirty anymore, the change is not commited or published, how do I know where are my changes ? nicolai
