The active controls for View Selection on the ExperimentWidget's Views tab are visible and enabled, but don't do anything, until there is a selected model. Hide, or otherwise disable these until they are actually functional.
Maybe these should be hidden or disabled if there's only one view available in the comboBox list.
It might also be wise to have a background image (where a view would be displayed) pointing to the models at the left, informing the user that selecting one will bring up the requested data in a default view.
