I have created an App in Mendix Modeler and I started off by creating a new branch in which I will do my changes. I can see on the harddrive that the app is created and the directory has a .svn directory. I have downloaded TortoiseSVN and for some reason TortoiseSVN wont detect that the directory is a Subversion project. I see a context menu and it has 2 options import and repo browser, No add, commit options. I have tried 3 versions of Subversion including 1.7 and they don’t work. Is anybody else having these issues?
I feel you should make the changes in the Mendix Modeler itself. Try and see if the modeler error pane is showing any errors.
