Sear Michael, please always include mitk-users at sourceforge to your CC list to also give the list the opportunity to listen and hopefully answer as well.
Yes, currently there are two files statemachine.xml in the repository. See bug #3701 (http://bugs.mitk.org/show_bug.cgi?id=3701) for further information. This will be changed in the future. The one in MITK/CoreUI/Bundles/org.mitk.gui.qt.common/resources is the one that is used when you start the ExtApp. The file will be read during startup so that changes prior to startup will have an effect. Please test again and be sure to change the right pattern. (The Statemachine.zip file contains the statemachine editor ( http://mbits/doxygen/StatemachineEditor.html ).)

Things are a little clearer now, although one thing is still confusing me: There are two statemachine.xml: MITK/Core/Code and in MITK/CoreUI/Bundles/org.mitk.gui.qt.common/resources But changes in either of them seem to be ignored. It does not matter if I add my own transitions, like the one you suggested or if I remove existing ones... the behavior stays the same. Is it possible that global interaction gets its states and transitions from some different place? We are using the Blueberry framework. I see that there is also a StateMachines.zip file, but I'm not quite sure what it is used for.
