I have a list in which I want the user to be able to select the name of 1 or more lists/libraries that exist on the account. I know I can use
_vti_bin/lists.asmx?op=GetListCollection to get a list of lists and I figure I could create a WSDL data source with it. But I can't figure out how to use that WSDL data source as the source for a lookup column.
And/or if there is any other way to do what I need?
