While doing some exploratory work, i tried to clone the default Enterprise Wiki pagelayout and added some of my own controls, everything went smooth until when i try to save & close the page and i was thrown the following error:
"failed to get value of the wiki categories column from the managed metadata field type control invalid field name"
Googling didn't help much as most of them prompted me to activate the taxonomy site feature (which after verifying, it was already active), after some head scratching, i realized that when i duplicate the layout page, i've used the default Associated Content Type as "Article Page" instead of "Enterprise Wiki Page", after editing the associated content type, all went well :)
