I've create a custom field type in sharepoint with a custom editor to get some properties from the user while creating the column. But if i go to the create column page and select the radio button corresponding to my field i'm getting "Unknown error" error. What could cause the problem? fldtypes xml? editorcontrol.ascx? or editorcontrol.cs?
