Subject Re: [JELLY] Key listeners
Date Tue, 22 Jul 2003 22:43:40 GMT
I have no experience writing test cases, but I can take a look at it.

Question, is this the only way to get key listeners on a component?  I'd 
really like the ability to add a key or focus listener that can use jexl 
or bsf in the xml.
