Hahahah, I didn't realize the embedded java code was jexl.  :)

I tried just adding my key listener and it didn't work.

Here is the code
  <textField var="customerId" action="${load}" text="" columns="10">
    ${addKeyListener(new JellyKeyAdapter())}
  </textField>

Where JellyKeyAdapter() is a class I have in the same directory as my 
jelly file.  Jexl complains of a parse error.
