hi petros,
right... you can't use it in an onAction method (component event
method)
a possible solution is to save some informaton in a persistent
field (session or flash) that is then evaluated during the render
phase.
as you know, after each component event t5 performs a redirect
to initiate the page rendering. because of the statelessness of
t5 components/pages you have to somehow remember the
state info yourself if page/component rendering depends on a
previous component action.
hope this makes sense :)...
a simple example:
@Persist("flash")
private boolean renderScriptFlag;
void onActionFromLink()
{
renderScript = true;
}
void beginRender()
{
if(renderScriptFlag)
renderSuport.addScript(....);
}
g,
kris

Re: @Environment problem
Thanks Kris/Sven,
The version I am using is 5.0.13.
Kris, if I am understanding your explanation correctly this means I have
no
way of using this code
renderSupport.addScript("%s.show%s(%s);", window1.getClientId(),
isCenter()
? "Center" : "", isModal());
within an action method ?
PS: This is my original issue
http://www.nabble.com/t5components---Window-to18087605.html
Sorry if I complicated things by creating two different issues.
Sven, sorry about all these questions but my Javascript skills are very
limited.
