Trying to set Edit Widget fields Grouping to collapse

[irmcintosh]

I am trying to set the Edit Widget fieldGrouping initialState to collapse. I am confused why it isn't working. I've attached to what I have written.

The only place I see 'initialState' being used in the fieldConfig is identified under FieldGroupConfig and InfoFieldGroup, both of which identify the setting as "colllapsed".  I added both of those classes and set my initialState to "collapsed" and it didn't work either.  I think this is a bug and you should follow up with a ticket with Esri as I would sure like to have that functionality work.
