IllegalStateException recovery [message #127275] Fri, 30 June 2006 19:54 Go to next message

I'm using Callisto.
I've got a Swing JTable, and I've set a model on it that will provide
data. I had not configured the data source, so I got an
IllegalStateException. However, the exception screws up the visual
editor view so that none of the visuals draw. I can see the frame
outline, and I can hover over components and see the hover text, but
none of them draw correctly. If I have configured my data source
correctly for the JTable, all of the widgets draw correctly.

1. Maybe exceptions are bubbling out too far? Trace below.
2. If I correct the source code (by commenting out the setModel() call)
and close/reopen the VisualEditor instance, the visuals in the view are
still broken. I seem to have to restart my Eclipse session to fix it.

Any ideas?

Thanks,
Ernest

Ernest,

If you're using a model that requires real work to be done, like
establishing a jdbc connection, the best practice is to detect the
difference between design time and run time behavior and provide mock
data in design time. VE supports doing this by adding the following
check to your code:

if (java.beans.Beans.isDesignTime()) {
// provide mock data
} else {
// provide real data
}

Hope this helps,
- Jeff

Jeff,

Yes, using the design-time flag seemed to be working for me, so I'm glad
to get your confirmation that this is the supported way of doing things.

However, my concern about badly-behaved models still stands.

Thanks,
Ernest
