 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.

  Hello,
 
  I'm using the InlineFrame class to display an IFrame. Now the IFrame
  is added in a dialog prompt, which is not visible by default. The user
  has to click a certain link to see the IFrame in the dialog prompt.
 
  Unfortunately the browser loads the URL defined in the source
  attribute, no matter if the IFrame is visible or not. In my opinion,
  it would be better to load the content only if the iframe is visible.
 
  A solution to achieve this goal is explained here:

  ayed
 
  But for some reason the onComponentTag(ComonentTag tag) is declared
  final in the InlineFrame class.
  I don't understand why the method is final and I'm a bit clueless how
  to proceed.
 
  Hopefully someone can help me.
 
  Thanks,
