If you're not refetching it and literally holding onto the same EO
instance in your component, you're doing something wrong, because that
works. If you're setting a var on an EO and then refetching it, that
will not work -- you get a new EO. I would add a print out in your
boolean's set method to see if someone is inadvertently setting it to
false and i woudl print out System.identityHashCode(yourEO). If it's
the same instance, that will be the same. If it's a different
instance (which is probably what is happening) it will not match.

I am running into a problem that I think may be related to the way
EOs are created/managed in memory. I have an object that I pass in
to a component. That object has some boolean variables that are not
backed by the DB. They are simply declared in the class file, public
boolean boolvar;
If I set this variable and then display the page with a checkbox
bound to this variable it shows the correct state. If I leave the
page and go back to it then the state of the checkbox always reverts
to false.
It seems like I am getting a newly created object instead of the one
that was already created. Other variables that are DB backed seem
fine. Is this normal? Do EOs get created and destroyed regularly,
and can I not rely on getting the same object instance if one was
already fetched and created in memory? Or, am I barking up the wrong
tree and something else is going on?
Thanks,
Kevin
