Joomla 3.3.3. Virtuemart 2.9.9
Virtuemart - products -> I open a product -> Tab custom fields -> type in the product SKU so a few blank popups appear. When I select one of those blank popups, the field is automatically filled in with the name of that product but..... When I click safe: ... nothing gets safed. The field is empty again.
Works fine for me in VM2.9.9a http://dev.virtuemart.net/attachments/download/772/com_virtuemart.2.9.9a_extract_first.zip
Great it works for you. For me it does not.
I tested firefox and chrome.
Joomla! 3.3.3 and VM 2.9.9a PHP Version 5.3.28
Hope this will be sorted in VM3.
