If you have tried implementing something that required a mechanism more complex than the default one provided by LightSwitch regarding default screen selection, you already are familiar with the limitations.
For the ones that don’t get what I mean, a very common example is open the details screen of an object from a list containing items from a view (database view) that include the id of the original object.

Finally a well written article that talks about LightSwitch (also I am quoted in it several times):
Everyone’s aiming for the “citizen developer,” but lately that elusive customer has led Microsoft on a snipe hunt. With LightSwitch, the company has a rapid application development (RAD) tool, that no one—not even Redmond or its partners—seems to know quite what to do with......

Crashing your LightSwitch project with your extensions is a piece of cake. The first simplest thing I did was change the business type to handle integer values instead of string ones. But I changed “:String” to “:Int”. That was enough to do it. It should be...
