Hi,
according to your code, you define a local variable display_url in the layout of your page but without setting any value:
<% DATA:     display_url    TYPE  STRING. %>
<iframe src="<%= display_url %>" width="100%" height="500px">
  </iframe>
I guess, you have also a page attribute or local variable in your eventHandler named display_url.
So the local definition in the layout overrides the global page attribute an its value.
Use just the page attribute to set the value on initialization and display it in the layout.
Best regards,
