Finder control

Greetings everyone,

I'm trying to wrap my head around the Finder control.    I can't seem to find any good examples of how to implement it in conjunction with business objects

I was wondering if there would be any insight/guidance or code examples in the community.  When I implement it, I get a "select" link with a message that nothing has been selected.

I'm guessing this is where the business object comes into play.   Thanks so much in advance.  Perhaps, I don't know what I should expect from it.
