Dear LabKey developers,

We have observed a strange behavior when editing a row in a list using the "EDIT" link menu in the list view.
That is happening when a list has a primary with column name containing a blank, e.g. when importing your Demographics dataset example which contains the column name "Participant ID".
If, in the procedure of creating the new list, the primary column is called "Participant ID", editing a row will try to change the primary key value to some value similar to "{101344,101344}"
If the primary key column is called "ParticipantID" (no blank in the column name), editing of a row works properly.

I hope that can help.
