That's how you should do it: a distinct RequestFactoryEditorDriver. We're doing just that, so I can guarantee that it works (or can be made to work). You'd maybe want to also implement HasRequestContext so you can pass the same RequestContext to the "child" RequestFactoryEditorDriver that you use in the "parent one".

But that (probably, you'd have to try it) doesn't preclude the latter usage; you wouldn't use the ValuePicker as an editor by itself though, just as a widget around a CellList (that CellList would be be used with an HasDataEditor to populate it "dynamically"). -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
