Okay
I've decided to let the renderer do the work of rendering parent and
children. Moving on from that I'm having trouble understanding where I
want to add child components. Doing this in the renderer seems wrong
as I want to have different validators associated with components
depending on a which country the component is being created for..
I want to do something like
if("EN".equals(mycomponent.getCountry ()) {
//add UIInputs according to this country.
}
I'm just unsure which method in UIComponent I want to do this in.
This is the kind of use case where Shale's[1] "view controller" API becomes useful. The prerender() method is a perfect place to do this sort of thing -- it is called immediately before rendering, even on the initial display of a page.
You can do the same thing yourself without Shale, but it's quite a bit more work -- define a PhaseListener that listens for Render Response phase, and set things up in the beforePhase() method. But it's a lot easier to let the framework call you at the right time.
