Since the redesign of the QmitkFunctionality API, if I open a 3D+t image, the time slider in the Image Navigator shows an incorrect time range, and changing the time step does not make any visible changes in the render windows.

I attached an image to demonstrate the problem. I opened it with the ExtApp. The real time step number is 6. The navigator shows 10, but pulling the slider does not have any effect.

With ImageJ it is correct, and it was also before the API change.
