Re: recognizing errors in embedded JS code

This might be something that the sdbg plugin can handle or should be able to handle in the long run..

Hi,

when using embedded JS code, I found that I sometimes do not recognize simple errors like this:

 private native JavaScriptObject makeAnnotation (int x,int y,int as,char c)

 /*-{

  var pi = i * cs + cs / 2;

 ...

  return (i);

 }-*/;

In this case, variable i is not defined. But there is no compiler or runtime error reported. It simply doesn't work and you get the (chrome) browser message "paused in debugger". When you continue debugging, you find yourself somewhere in exception handling code in Impl.java. Then, after setting additional breakpoints, you fnally see, what's wrong.

This process is time-consuming. How can you detect such simple errors sooner?

Thanks
Magnus
