Close button in pop-up header

Hi all,

I work on Web dynpro 7.2 and I want to have a close button in the header of some pop-up that I have.

Corresponding to this issue, I 've found that document that talking about pop-up : http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/a04870c5-749b-2b10-06ba-d25515ef39e3?QuickLink=index&overridelayout=true&35665408432492.

The problem is that the author of this document use "IWDWindowViewElement" to add the close button but it works only with SAP Netweaver 7.1.

A workaround for this issue is to add a standard button in the pop-up view, but it's not really what I want.

Regards,

Nicolas
