Finding a component with a specific id

[Simon Kitching]

Hi,

From a custom renderer I need to be able to find a component with a 
specific id.

Page:
  <o:colSelector tableId="table1" .../>

  <t:dataTable id="table1" ...>
     ..
  </t:dataTable>

From the renderer for the o:colSelector I've tried:
  UIComponent table = facesContext.getViewRoot().findComponent(tableId);
  UIComponent table = component.findComponent(tableId);
  UIComponent table = component.findComponent(":" + tableId);
but had no luck.

The table is enclosed in a subview named "body", so the id actually gets 
output as "body:table1". I've tried all the above with that string too, 
and no luck.

Any ideas how I should locate that table component by id??
[And BTW, is it possible for a component in a naming container to have 
an id that is *not* prefixed by its NamingContainer parent's id?]


On a related note, looking at the source for UIComponent.findComponent, 
I see it calls _ComponentUtils.findComponent which is as follows.

    static UIComponent findComponent(UIComponent findBase, String id)
    {
        if (idsAreEqual(id,findBase))
        {
            return findBase;
        }

        for (Iterator it = findBase.getFacetsAndChildren();
          it.hasNext(); )
        {
            UIComponent childOrFacet = (UIComponent)it.next();
            if (!(childOrFacet instanceof NamingContainer))
            {
                UIComponent find = findComponent(childOrFacet, id);
                if (find != null) return find;
            }
            else if (idsAreEqual(id,childOrFacet))
            {
                return childOrFacet;
            }
        }

        return null;
    }

What's the point of that "instanceof NamingContainer"? Why doesn't the 
search recurse into NamingContainer children of findBase?

Thanks,

Simon
