Bug appears just the first time toggling the visibility of the other node.
After select and toggle the visibility of the pointset and image manually it works correct.

QmitkPointBasedRegistrationView.cpp #1346
the comment of this line says "hide all images" -> why hiding all images?!

deleting this line solves the problem ... but maybe there could be some side effects

Another visibility problem:
Step1:

• load 2 images
• select datanode1 frist and then the other (datanode2)
• deselect all
• do the same again

-> visibility of all datanodes is toggled

Step2:
-select datanode2 first and then datanode1
-deselect all
-do the same again
-> visibility of all datanodes is toggled, you can start from step1 again

Another visibility problem:

• load 2 images
• select both
• click "toggle point editing"-button of fixed data
• expand fixed datanode in data manager

->the visibility of all datanodes is set to false

QmitkPointBasedRegistrationView.cpp

The function SetImagesVisible(selection) is responsible for the strange behavior for the bugs above.

see no sense of "SetImagesVisible(selection)" -> deleted the method

after deleting everything works like expected
