You have a bit of a workflow going on in that requirement. - If property is null, provide selectable list of string values obtained from an arbitrary entity. - If property is not null allow its string value to be edited free from.
In addition you will need to handle: - Do you need to be able to supply a qualifier to restrict the list of values - Do you need the ability to clear the selected value, and pick a new one from the list As such, I don't believe there is a pre-baked D2W component that will do exactly what you want. So you are probably gonna have to create a custom one, the simplest route is documented in step 7 here: <http://wiki.objectstyle.org/confluence/display/WO/D2W+Rules+Reference+-+Cookbook+-+FAQ> Alternately, you could subclass ERDCustomComponent.
