SlicerIGT Collect Points to Model Node

This is probably a bug report:
Slicer 4.10.2, SlicerIGT revision 00ff9bf

I try to use the ‘Collect Points’ module to collect points into a model node with the following settings (autocollect on):
Then, in the transforms module, I change the translation of LinearTransform_3 with the sliders.
The points displayed by the model are quite weird:

Only, when I click ‘Delete the last point from the output node’, the data displays correctly:

I am not able to find the part of the code that causes the problem here. I would be grateful for any help.

Thanks for reporting this issue, it seems to happen in both 4.10 and 4.11. There seems to be a problem with the Model observers.

I’ll take a look at it.

I’ve created a fix. It should be available in the 4.11 release tomorrow.
