Webdynpro freestyle with IFRAME component

Hi all,

from my FPM application i have called a freestyle webdynpro application to show Webgui URL inside an IFRAME component.

The URL works correctly but i have a compatibility problem with it.

If i run an external window from webdynpro abap there are no problems, instead if URL is displayed inside IFRAME component all matchcodes are showed in a wrong format.

Example file is attached. (with matchcodes problems...)

How can i resolve this problem with IFRAME component?

Thanks in advance.

Regards.

Dario.
