1. Step1: Selecting an operation in a study
Step1: Selecting an operation in a study. In this case all motion parameters are defined.

2. Step2: Remove all motion parameters of that operation
Step2: Remove all motion parameters of that operation. They all disappear in path editor and parameters viewer. Only the default values are shown the path editor.
 correct

3. Step3: Setting all locations in the operation to PTP interpolation
Step3: Setting all locations in the operation to PTP interpolation. All values are shown correctly in the path editor and in the parameters viewer (RRS_MOTION_TYPE = 1)
 correct

4. Step4: Try to change some locations to LIN interpolation and CIRC interpolation. All values are shown correctly in the path editor and in the parameters viewer (RRS_MOTION_TYPE = 2) - but only in this case.
 correct

5. Step5: Try to change the LIN-locations to KLIN interpolation and CIRC-locations to KCIRC interpolation. All values are shown correctly in the parameters viewer (RRS_MOTION_TYPE = 2 and VKRC_MOVE_TYPE = 4), but the columns Interp. and Ve in the path editor are not updated
 wrong

6. Step6: Manually change the Interp
Step6: Manually change the Interp.-column to KLIN and KCIRC interpolation. All values are then shown correctly in the path editor.
 correct

7. Step7: Try to change back all KLIN-locations to LIN interpolation and KCIRC-locations to CIRC interpolation. The columns Interp. and Ve in the path editor are not updated
 wrong
Step8: Manually change the Interp.-column to LIN and CIRC interpolation. All values are then shown correctly in the path editor.
 correct

8. I suppose some columns in the path editor are only updated with the RRS_MOTION_TYPE attribute. LIN and KLIN have both the value 2, CIRC and KCIRC both value 4 and therefore some columns are not updated.
