Re: [JELLY] Key listeners

[Sean Ferguson]

Thanks for the tip on using j:new.  I really wish there was some good 
documentation on Jelly.

One thing I think I should point out that may or may not be a bug is 
that if I put the code inside the declaration of the textfield, it 
doesn't catch events.

<textField var="customerId" text="" columns="10">
  <core:new var="keyAdapter" className="JellyKeyAdapter"/>
  ${customerId.addKeyListener(keyAdapter)}
</textField>
But if I move the code block outside of the declaration, it works fine.
<textField var="customerId" text="" columns="10"/>
<core:new var="keyAdapter" className="JellyKeyAdapter"/>
${customerId.addKeyListener(keyAdapter)}
I know I don't understand fully how Jelly works, but I would have 
thought it would work both ways.

Again, thanks for you help!

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.


Jexl doesn't support new, and all method calls must be prefixed with the 
object on which they are called.  However, you can do something like this:

<textField var="customerId" action="${load}" text="" columns="10">
 <j:new var="keyAdapter" className="com.foo.bar.JellyKeyAdapter"/>
 ${customerId.addKeyListener(keyAdapter)}
</textField>
