Keeping track of foundsets in 5.2

[BulldogBen]

I've just started running into issues where setFoundSetFilterParam on one form affects the foundset when I navigate to another. I want to get in a good habit from the start, so I can keep track of filters I've set. The two methods I can see are...

1) Always set namedFoundSet to "separate" when a form is going to use setFoundSetFilterParam. This seems to work, but it would be easy to forget.

2) Apply filter in onShow event, giving it a name, and as soon as you write that code always use removeFoundSetFilterParam on the onHide event. This feels better practice to me (may as well use the new 5.2 functionality)

... comments on these two methods, and things my inexperienced self may have overlooked much appreciated.
