In your note at the end that starts “If your dialog is already visible, do not create another one”, you said “If your dialog is already visible, ignore the next exception.” How do you do that?

Thanks for the tips. We were thinking of a good exception handling/error reporting for our rich application. That’s really great I’ve found your entry before making production code. I guess you’ve saved me couple of hours.

This is a nice feature, but I’d like to point out on more “gotcha” that caught me out…

I had a RuntimeException that was being thrown and never caught by any of my default handlers… it just sort of disappeared. Turns out that the RuntimeException was being raised thru our code and then passed into the hands of a third party library which had an empty try-catch block. So I /thought/ my default handler would catch it, but it turned out that the 3rd party library was just failing silently.

So we had to recant on the idea that the default handlers could be used as an all-the-time replacement for try/catch blocks. Don’t go ripping out all your try/catch code just yet.

This is the first I hear of this. Can be useful.
Thank you.

Nice post. How did you find out about this feature? I consider myself pretty well informed on Java but never came across it. They should have advertised this more.

I can see this being useful in many ways outside of Swing as well. Something to keep in the old toolbox. Thanks!

very nice entry. Just last week i was almost exactly he same thing, but your tips at the end are very useful, i see that i have to add some more details. Our implementation has a bonus tough, it has “show error details” for developers to see whats going on in client test systems easily..
