https://community.bistudio.com/wiki/hashValue supports a lot of types, but notably locations, controls and displays are missing. Can those be supported too?
https://community.bistudio.com/wiki/HashMap#Supported_Key_Types If hashValue supports objects and groups, can't hashmaps support them natively too? What about locations, controls and displays?
objects, groups, controls and displays can become null. That's why they are not allowed as keys in hashmaps.
What hash would you expect for a display?
If you close the display and reopen it. Would the new one have the same hash?
Afterall its the same "thing" ?
Would the new one have the same hash?
I'd say no, as it's a different instance of the same thing - otherwise imo all objects should have the same hashValue.
But yea, it makes sense not to allow those types. I imagine the same is true for locations, so this ticket can be closed.
