Now why didn't I think oft hat. Thank you Martin.

Maybe we can remove the final declaration in the next release (if there is no 
objections)

Cheers,

Betreff: Re: Loading content of IFrames only when displayed

Hi,

You can use custom Behavior that removes the 'url' attribute in its
#onComponentTag() and adds 'data-url' instead.
Component#onComponentTag() is executed before Behavior#onComponentTag() so it 
should work OK.
