Databound Dependent SelectIitem in ListGrid

SmartGWT Power 4.1

Hi,

I have an editable ListGrid with several columns, two of which are SelectItems. The value map for one SelectItem is dependent on the other. I'm looking to accomplish what's demonstrated in the showcase example ( http://www.smartclient.com/smartgwt/...endent_selects ), except have "Departments" (i.e. the dependent SelectItem) be databound.

My certain use case is to use two fields from the ListGridRecord to perform the fetch of the DataBound SelectItem.

Short of calling setEditorValueMapFunction() and performing my own fetch to populate the values, is there a mechanism within the framework that supports this?
