Re: Selecting list items from history actions using Activities and Places

Hi Thomas/Chris -

Thanks for the responses. I was missing the part about the build-in check for Place equality. Any idea how the equality check is implemented?

For example, if my Place has 2 fields - an integer and a string, is it implicitly true that 2 places are equal if those values are the same in both, or do I need to explicitly define an equals() method?

@Thomas - In the example you pointed me to, what prevents this from essentially creating an infinite loop? OnSelectionChange fires a new history event. The history handler responds, gets info and changes the selection, which would in turn fire a new history event. No?

If the value to be selected is the same as the already-selected one, then no SelectionChangeEvent is fired.

If the place to go to is the same as the current place, then this is a no-op too.

So there's no infinite loop.
