[cosmo-dev] how to configure javascript debugger

Hi Vaibhav

The core Web UI developers all use Firebug when developing in Firefox.  
As you've noticed, Firebug can be somewhat buggy, but with a few  
tweaks it yields what is probably the most flexible debugging  
environment currently available for a large application like ours.

Probably the biggest bug blocking current debugging workflows is this:


Essentially, Firebug's algorithm for detecting eval statements is  
pretty primitive, and isn't able to detect the main dojo.require eval,  
leading to a useless debugger. This can be fixed by using an entirely  
un-packaged codebase for debugging.

To do this, you should first head into $COSMO_ROOT/cosmo-js and run

mvn package;

Next, follow the instructions here:


finally, head into $COSMO_ROOT/cosmo/src/main/webapp/js and do:

mv dojo dojo-original;
ln -s ../../../../../cosmo-js/dojo-src/dojo

The next time you load the application you should have more luck  
setting breakpoints.

Please feel free to ask more questions if you have trouble,
