The use of the QmitkMxNMultiWidget is currently not possible due to different render window names.
In many cases hard-coded names like "stdmulti.widget0", "stdmulti.widget1" etc. were used, which do not necessarily exist anymore when using the mxnMultiWidget.
The following list contains classes that have these hard-coded names and need to be refactored:
QmitkSliceBasedInterpolatorWidget(was removed in T28669: [Segmentation] QmitkSlicesInterpolator and QmitkSliceBasedInterpolatorWidget seem to be redundant)
QmitkSlicesInterpolator(see T29362: [Multi widget] Plane suggestion of QmitkSlicesInterpolator does not work correctly)
- has partially been refactored
MovieMaker (see T29302: Movie maker plugin does not work correctly with the new mxn multi widget)
QmitkUSNavigationMarkerPlacement(see T29303: IGT classes do not work correctly with the new mxn multi widget
