jMP hangs when nifty element has same tag twice when hitting the Design button

If you have, for example, a panel in which you’ve defined height=“50px” and another height=“xx” jMP will crash after giving you a parsing error.

Although I got the parsing error most times, it happened once that jMP simply hung without any message.

Thanks, gonna check the threading on that message display.

Edit: Oh, and how exactly looks “crash”?

It doesn’t crash per say. There’s no stack or JVM message. jMP just hangs. Can’t do anything. Once the cursor changed to “busy” after clicking on the error message. The rest of the time nothing happens. jMP stays open until Windows grays out the app and eventually asks you if you want to close it or wait. Waiting doesn’t do anything (obviously).
