add javascript declaration to header - like richfaces does

[holger_p]

Hello,

i noticed that richfaces adds the necessary javascript / ressources to the head section of the document.

This behaviour i need to reimplement for my own custom jsf component.
In 2 month i can switch to cdk which will ?solve the problem? but currently i have to work without.

i noticed the classes :
AbstractInsertRenderer.java and HeaderResourcesRendererBase are involed somehow, but i can see where actually the resource is inserted in the head section.

Can you tell me how richfaces does this? (is the filter involed maybe?)
Just some hints so i can find out myself somehow.

Thx very much,
Holger

Any richfaces developer here that can maybe give me a hint how richfaces does its job with adding javascript resources to head?

Thx very much,
Holger

Holger,

That happens in one of three parsers, invoked by filter. E.g.: org.ajax4jsf.webapp.nekko.NekkoParser.ViewStateFilter#insertResources(). All parsers implement org.ajax4jsf.webapp.HtmlParser interface, you can find them by invoking "Open hierarchy" command in your IDE.

Also these class code: org.ajax4jsf.context.ViewResources maybe helpful to know what resources are collected.

ah ok, so the filter is envolved and starts the insertion, i assumed the filter finally does the job but wasnt sure.

Hey thx very much, helped me a lot - me sure i can implement same behaviour for my app :-)

Btw: Richfaces is really nice.

Bye,
Holger
