I instantiate my Iframe in the panel's onBeforeRender() to ensure there's a
page to attach the iFrame to.
I think the oncomponenttag() happens before the onBeforeRender() which means
that if i do:
tag.put("target", myIFrame.getMarkupId());
myIFrame is null.
So, where can I instantiate my Iframe to ensure I can pass it's ref. to the
panel's oncomponenttag method?
Sorry if i'm missing something obvious...
Thanks
