When doing a breaking change of an eSpace, OutSystems lists the eSpaces that are 'broken', you now have seach the eSpaces, open them, check and republish them and that can be a lot of work. Also it's easy to forget one of the broken eSpaces.
Idea : If there are broken eSpaces give a warning message with the option to open all the broken eSpaces, thus it's impossible to forget and it is a lot quicker to solve the problems.
