Hi Koshi,
Generally, having the component tree vary dynamically is not done with
JSF. If you want a choice of two different components, then typically
you define both of them in the page, then use the "rendered" property to
ensure that only the one you want is output.
There is certainly no JSF tag in standard JSF or Tomahawk that allows a
random component to be inserted into the tree. I don't initially see why
it wouldn't be possible to do this, but it certainly isn't common JSF
practice AFAIK.
If you *did* want to create such a component, I can imagine one that has
a single child; on encodeBegin it evaluates its value expression, sets
that component as its child then passes on the encodeBegin call. All
other component methods would get delegated down to the child as normal.
Regards,
Simon

I have a managed bean with a method that returns a UIComponent,
sometimes a commandLink or a outputText.
public UIComponent getComponent ()
{
UIComponent link ;
if (this.isAction ()) {
link = new HtmlCommandLink ();
link.setTitle (this.title);
MethodBinding method = FacesContext.getCurrentInstance
().getApplication ().
createMethodBinding (this.value, null);
link.setAction (method);
}
else {
link = new HtmlOutputText ();
link.setValue (this.title);
}
return link;
}
Then, in the view i imagine something like that
:
<t:component value="#{managedBean.component}" />
is this possible or i have to create a custom component ???
thanks in advance, and sorry for my english mistakes.
