    When you post feature items like this for upcoming releases it would help to put the EAP version its applicable to.

    Good advice!
    This feature is available in last EAP of IDEA X (98.187)

    I tried with version 98.311 and the debugger did not stop in the GSP.

    Dierk Koenig,
    Now debugger stops at expressions like ‘${…}’ only. Did you set breakpoint to expression like ‘< % ... %>‘?

    I’m using 10.0.0.1 and for me it’s not working.
    I’ve set the breakpoint at ‘${…}’, but the only thing what is happening:
    IDEA doesn’t stop - browser doesn’t stop running, it loads and loads and loads (FF) - IDEA consumes the whole CPU - only a restart of IDEA helped!!!

    Just confirmed the same as Charlie with IDEA 10.0.1 It won’t stop on the breakpoint, goes into an endless loop and requires a restart of IDEA to break out of that situation.

    I had to come back and report that after being contacted by Sergey at Jetbrains, I tried to reproduce the problem. He asked for the GSP that was causing problems and I went about trying to figure out which GSP it was so I could send it to him.

    I tried about 50% of the pages in my app and not once could I reproduce the situation I mentioned above on Jan 29. It’s only been a few days and I didn’t change much, if any, code between Jan 29 and today. The only significant event between those two dates was that I rebooted my machine.

    On Jan 29, I could not get this feature to work at all. Today, I cannot reproduce the problem and IDEA stops on any breakpoint I set, on any GSP.

    If I can reproduce the problem, I’ll come back to report my results, but for now, I’ll chalk it up to some weird environmental thing.

    Being able to stop on a breakpoint in a GSP is really nice for some problems. I’m looking forward to using this feature.

    If the problem appears again attach the stacktrace, please. (You can get it using command ‘jstack’)
