HierarchySlicer Copy/sync Bug

[SQLMonger]

This error can be repicated by copying a HierarchySlicer component from one page to another.
When prompted to Sync the slicer across pages or not, choosing "Yes" will result in the error.
The component is copied, but no sync between the original and the copy is set up.

Based on the fact that the HierarchySlicer does not show up in the Sync Slicers panel, it must not be capable of being synchronized. It would be better if the paste operation could determine this and let you know instead of blowing up. Better yet, enable sync on the HierarchySlicer.

@SQLMonger ,

Actually , in some reports, I can reproduce your error, in some reports, everything works well.

The HierarchySlicer custom visual is developed by  Jan Pieter Posthuma, based on his blog, sync Slicers are not yet supported: the custom visuals API is preventing this. I would recommend you contact Jan Pieter Posthuma about the above issue.

Thanks for the feedback. I did not realize it was not a Microsoft developed component. Will check next time before posting...
