Hello.

I'm trying to use SharePoint:InputFormTextBox as custom richtextfield editor on one of forms (it is edit form of a document library, where default form is hidden by webPartManager.CloseWebPart and custom webpart added).

When edit form is open in the same window (when editing item), control renders as it should. But when I'm adding new document and edit form is opened in modal dialog, the script error is thrown:

SCRIPT5007: Unable to get property 'overrides' of undefined or null reference 

Control remains unrendered - just a textarea without controls ribbon in it.

Can anyone tell, what should I enable, where and when? :)
