I have a custom form for Contact which has a sub-grid containing the Address (Contact_CustomerAddress) entities. I have been using this form successfully since CRM 2011 without a problem. We have recently upgraded from CRM 2013 to CRM 2016 and now can not add address records. The list renders but nothing happens when the "+" button is clicked.
To attempt to isolate the problem, I added the "Address (Parent)" sub grid to the standard Contact form and the behaviour is identical.
There are no Javascript errors showing in the console and not other errors being reported that I can see.
Does anyone have any ideas? This worked perfectly well in older versions.
Thanks in advance.
