Exception in Debug but not in Run mode

[mukarev]

Hi folks,

currently I'm implementing a client for jWebsocket.

I got a strange error.

If I try my implementation in debug mode, I get an JavaScriptException because of a null value. If I run it in run mode there's no problem - everything's working fine.

Exception like this:

The exception seems to occur because of "jthis" is nulled in some invoking JavaScript methods.

So my question -> is this a problem of my implementation or could it be an error in the debug plugin? Don't know where to look at.

Thanks in advance.
