I just don't get Intellijs Maven-Module-mechanism. I'm trying to create a maven multimodule project, but strange things happen... I I create a parent module with just a pom and two submodules "core" and "web", the parent is not displayed in the "Project" view, I just see the two submodules. Also, in the Maven-Window, the parent-module is dark grey.
Also, if I try to group those two modules, Intellij sometimes removes one module from this group. I don't know why, and I haven't figured out yet what triggeres that behaviour, but it only happens in this new project-setup. I've got several other maven projects, but it doesn't happen there at all!
