ContextException - populating drop down. (newbie question)

18 Views

I map the selectedConfiguration attribute to the component context's selectedConfiguration so that I can access the value in the subsequent views.

On the current view, the selectedConfiguration corresponds to a dropdown. This exception gets thrown on the line :

ISimpleTypeModifiable myType = wdControllerAPI.getContext().getModifiableTypeOf("selectedConfiguration");

How can I populate a drop down if the context for that drop down is mapped to the component context.
