Pb with single category embedded view

Hello everybody,

My problem is the following :

I created a page with an embedded view.

This embedded view is categorized and uses the single category property (as Username in entry).

If i try, with a Notes 7 client, to use the “Collapse all” button in this view, a problem occurs: data dissapears, the embedded view becomes empty.

If i select another view in my database then reopen the embedded view, data is visible again.

I found, on the DeveloperWorks site, something about this problem but it told that it is fixed (from Notes 6.5.5 : SPR# GPKS63TBWA).

For me, it seems that it’s not fixed.

Could you help me to solve my problem or tell me who I must inform?

Thanks in advance for all of your replies.
