Web Dynpro Debugging

Hi,

can anyone tell me whether of not it is possible to add Watchpoints in the Web Dynpro debugger. I found the Add Java Watch Expression, but how do I make a watchpoint out of that?

Example:

I only what to break when a counter hits 10. How can I achieve this in the Web Dynpro debugger? ... please provide concrete code ...

Any help is greatly appreciated.

THANKS
