Hi Hans,
=20
I was able to reproduce the problem in a very simple Jelly script. See =
it below:
=20
<?xml version=3D"1.0"?>
<j:jelly xmlns:j=3D"jelly:core" xmlns:sw=3D"jelly:swing" =
xmlns:log=3D"jelly:log">
  <sw:action var=3D"exitAction" name=3D"Exit">
      <log:info>EXIT action!</log:info>     =20
  </sw:action>
  <sw:frame title=3D"Jelly Swing" var=3D"frame" location=3D"100,100" =
size=3D"450,300">
  </sw:frame>
  ${frame.show()}
</j:jelly>

Whenever I run this script, the action is always executed in the first =
place.
Any help will be appreciated.
Thanks,
Dario

	I cannot reproduce this behavior of having action tags executed =
immediately.
	I've checked in a test for this behavior as well (which passes).
=09
	My guess is that you're defining the action tag incorrectly, could you
	attach a Jelly snippet that reproduces the problem?

	Hi Paul,
=09
	Thanks for the tips.
	However I am still having problem getting the swing to work. :-(
	I tried to use the code snippet about the System.exit, but it didn=B4t =
work.
	Regarding the CardLayout, I couldn=B4t find its tag in the jelly swing
	documentation. Do you happen to have an example about how to use it ?
=09
	One thing I=B4ve noticed when using Jelly Swing is that any action you =
define
	in the jelly script is always executed as of the script startup, even =
though
	an event is not triggered yet. Do you know if this is an expected =
behaviour
	? I thought any action would be executed only if an event associated to =
it
	was activated.
=09
	Regarding your reloadable strategy, I think it would be great to have
	something like that. We can discuss it later if you wish.
=09
	Thanks a bunch.
	Dario

	You might give a try with a CardLayout, or ?

=09
	Would the following work ?
	<j:invokeStatic className=3D"java.lang.System" method=3D"exit">
	        <arg>0</arg>
	</j:invokeStatic>
	There is also a quit in the swing-demo.

=09
	This is not easy, I feel. I've been working on reloadable swing
	components for a while where a script would be run again in order to
	populate the pane but I didn't come with a final solution.
	I know that you can get a similar effect by doing a bit more method
	invocations and variable assignments.
	   ${pane.remove(xx)}
=09
	My intent for reloadable component is, indeed, to have each component
	behave as a browser frame and request to re-run a population-script
	along a target.
=09
	Just thinking out loud, I seem to encounter that the following might be
	enough:
=09
	<sw:frame>
	  blabla
	   <sw:panel var=3D"myList"/>
	  </sw:frame>
=09
	and somewhere else (e.g. as a child of action:
=09
	<sw:target name=3D"panel">
	   <sw:label>casdasa</sw:label>
	   ....
	</sw:target>
=09
	That is, we would introduce a "target" element that would allow an
	component to be cleared than repopulated by its content...
	This seems suddenly pretty easy to implement compared to the
	"reloadable" kind of things I expected. Would it fit your task ?
