I am trying to develop a custom field in a list that will allow selection from entire Term Store. Fortunately I learned about TaxonomyWebTagging control and its ability to allow selection from multipe termsets when used programmatically.
I am developing a custom field type that allows selection from multiple termsets using this control. The field type works fine when adding or displaying the terms. It however breaks when Editing. When values are assigned to the TaxonomyWebTagging control
(on server side), it gives an error on client that "There was an error processign the request". (in a dialog box). No exception is raised on the server side.
I have made sure that value assigned are in correct format to the control.
There is no problem with the connection of control to metadata term store as when I cancel the dialog and start typing in the control, it resolves the term store values.
Any insight how to assign values in TaxonomyWebTagging Control will be highly appreciated.
