getChildCount returns 0 at encodeBegin

Hi,

I wonder why this happens,

public void encodeBegin(FacesContext context) throws IOException {
        log.debug("ChildCount:" + getChildCount());
}

public void encodeEnd(FacesContext context) throws IOException {
        log.debug("ChildCount:" + getChildCount());
}

For example in the jsp page, component's number of children is 3. At
encodeBegin log gives me 0 but at encodeEnd it gives 3.

Also when I override getRendersChildren to return true, encodeBegin log
gives 3 this time.

I'll be glad if you help me out,

Regards,

Cagatay,

Don't know if this is of any help to you, but Facelets also corrects
the component tree rendering problem if you can use Facelets.

Hi,

Thanks to Ed Burns, I've learned that this is a JSF issue, at first jsf
creates the component tree "during rendering components", in JSF 1.2 they've
fixed this by first creating the tree and then rendering it.
