Re: urlFor ResourceStreamRequestTarget returning null
thanks maarten, but i still can't get the url for the resource in the
renderHead method.
in the open flash chart example, there are two types of urls built:
- resourcereferences (easy peasy to get the url)
- resource, via RequestCycle.get().urlFor(OpenFlashChart.this,
IResourceListener.INTERFACE);
remember, my component is:
public abstract class SWFComponent extends WebMarkupContainer
implements IResourceListener, IHeaderContributor
in my case i need the url to a *resource*, so i tried:
a) RequestCycle.get().urlFor(SWFComponent.this,
IResourceListener.INTERFACE); or urlFor(IResourceListener.INTERFACE);
in the onBeforeRender method
=> it outputs the url to a *bookmarkable page* / not my resource:
?wicket:bookmarkablePage=:app.wicket.project.DocumentPage&wicket:interface=:2:docsPanel:viewer:flash::IResourceListener::
b) RequestCycle.get().urlFor(SWFComponent.this,
IResourceListener.INTERFACE); in the renderHead method
=> it outputs the url to another different *bookmarkable page* /
not my resource:
?wicket:bookmarkablePage=:app.wicket.document.DocumentDetailPage&wicket:interface=:10:detailPanel:viewer:flash::IResourceListener::
c) urlFor(IResourceListener.INTERFACE); in the renderHead method
=> *sometimes* it works.
this means *sometimes* it outputs
"?wicket:interface=:3:docsPanel:viewer:flash::IResourceListener:: "
(this is correct - it works) , but some other times it outputs "
?wicket:bookmarkablePage=:app.wicket.document.DocumentDetailPage&wicket:interface=:10:detailPanel:viewer:flash::IResourceListener::
" (this is not correct - it doesn't work).
this mysterious behaviour hasn't occured just once, it randomly
happened after compilation several times.
is this a bug or why does it behave like that? am i misusing the api?
should the resource, markup container and/or header contributor live
in different classes? suggestions?
thanks again

Re: urlFor ResourceStreamRequestTarget returning null
Posted by francisco treacy <fr...@gmail.com>.
ok, i solved my issue earlier by changing my IResourceListener in
favor of a plain old BookmarkablePage and this works fine now. as i
still think the behaviour i was experiencing is weird, i filed an
issue: https://issues.apache.org/jira/browse/WICKET-2204
additionally, the fact that urlFor ( ResourceStreamRequestTarget )
returns null still remains as a doubt.
so, roughly:
public class SWFPage extends WebPage {
private final String url;
public SWFPage(PageParameters params) {
getRequestCycle().setRequestTarget(new
ResourceStreamRequestTarget(new AbstractResourceStreamWriter() {
public void write(OutputStream output) {
try {
getResponse().getOutputStream().write( __ your byte array __ );
} catch (IOException e) {
throw new RuntimeException("Exception reading from bytes", e);
}
}
public String getContentType() {
return "application/x-shockwave-flash";
}
}));
}
used along with a Behavior that implements IHeaderContributor and
renders the needed javascript snippet to the html head works great.

Re: urlFor ResourceStreamRequestTarget returning null
Posted by francisco treacy <fr...@gmail.com>.
i updated to 1.4-rc2, but that didn't help.
right now, with exactly the same codebase, the url is being correctly
generated in my development environment - but outputting the bad url
in our continuous integration server version.
i set up several breakpoints in the WebRequestCodingStrategy class to
analyze step by step how urls are being built. but i have no idea when
it is going to start working differently again, and be able to
compare. i'm really puzzled.
hints anyone, on what could be causing this? so i can go debug there
thanks
