Hi Dave,
The error is at line 84 in primary_key.js (from screenshot).
In primary_key.js it requires MultiSelectAjaxControl. I guess patch of
MultiSelectControl was not applied correctly.
Can you please try again.
When testing it check if (in browser script tab) MultiSelectControl is
there in node.ui.js at line no 562 (approx).
Regards,
Harshal
