I have a parent panel that has several sub panels that are indirectly
dependent on their parent's model. By that I mean the parent panel's model
needs to load data that is independent of the data loaded in the sub panels,
but the sub panels are dependent on the data loaded by the parent to load
their specific data. I think this falls outside of the normal use of models
(LoadableDetachableModels that are separate but dependent on a chain of
other LoadableDetachableModels), but I thought I'd use the auto-magically
loading feature to easy the coding.
