Hello,  
I _think_ i found a bug, when i apply connectivity to extract the largest region of an source (tested unstructured grid and uniform rectilinear image) the fields of GlobalPointIds and GlobalCellIds disappear which (if i am not mistaken) removes the logic of using this filter previously on the pipeline…  
I am missing something? is this a bug? or something else?

It looks indeed like a bug!

I reproduced with a simple pipeline:

- Sphere
- GlobalPointAndCellIds
- Connectivity

Or maybe it is just a matter of `GlobalIds` vs `Ids` ?  
When using `PointAndCellIds` filter, arrays are correctly preserve after the Connectivity

yes, same here, i was using pointAndCellIDs to generate a id that is kept thought the opperations, and came up with ‘global cell and point ids’ and i was hmmmm… i think i should use this instead. (reason for my post). I will create an issue in case that it is a bug.at least i must say that it is a confusing name (if this is not a bug.)
