That dropdown with the MF datasource; that MF is the one in the screenshot yes?
Where do you actually set the association? Because if it cant retrieve the required object(s) over association means you haven't set it beforehand or at the very least it hasnt been committed yet.
I assume this dropdown is meant to set the association to the object. That means you cant use a retrieve over association to select the object because it doesnt exist. You can retrieve all the objects over database and filter/sort those depending on which ones you want selectable.
Hii.. I have used custom dropdown widget and things worked out. Thank you for the replies.. really appreciate it..
