I tried to implement a solution, inspiured by the source code of the
Zone component. It works (almost). The problem is that the afterLoad
block is empty for the dynamic request.
Can anybody see, at a first glance, what I am missing?
Next question would be: how can I force the update after loading? My
suggestion would be something like
renderSupport.addInit(" ??? ");
Thanks,
Andy
@SupportsInformalParameters
public class AfterLoadContent {
@Mixin
private DiscardBody discardBody;
@Inject
private Request request;
@Environmental
private RenderSupport renderSupport;
@Environmental
private ClientBehaviorSupport clientBehaviorSupport;
@Inject
private ComponentResources resources;
@Parameter(required=false, allowNull=false,
defaultPrefix=BindingConstants.LITERAL)
private String id;
@Parameter(required=true, allowNull=false,
defaultPrefix=BindingConstants.BLOCK)
private Block afterLoad;
@Parameter(required=true, allowNull=false,
defaultPrefix=BindingConstants.BLOCK)
private Block initial;
public Object beginRender(MarkupWriter writer) {
if(request.isXHR()) {
return afterLoad;
}
if (!resources.isBound("id")) {
id = renderSupport.allocateClientId(resources);
}
Element e = writer.element("div", "id", id);
resources.renderInformalParameters(writer);
e.addClassName("t-zone");
clientBehaviorSupport.addZone(id, "show", "highlight");
return initial;
}
public void afterRender(MarkupWriter writer) {
if(!request.isXHR()) {
writer.end();
}
}
from the template:
Initial
AfterLoad
Update Zone

Hi,
I need to build a page that dynamicly loads parts of itself after the
initial render in the browser. Those parts are the result of longer
running computation and can't be included when the page is rendered for
the first time.
I remember that a third party component that achieves something very
similar (dynamcly reloading parts, triggered automaticly) already
exists. But I don't know where I read about it (mailing list, wiki,
other sources) and cannot find it again.
Does anybody now what component I am talking about or has any pointers
how I can achieve my goal?
Andy
