Try to set your datascroller with ajaxSingle="false"
I have just tried it with ajaxSingle="false" unfortunatly I have the same result.
After refreshing the page by hitting F5 the hyperlinks works fine again.
The problem only occurs when using a rich:panel inside a h:commandlink element after using the datascroller.
When I remove the panel and only using h:outputText or h:graphicImage inside a h:commandlink element everythink works fine.
Is there a way to get this work some kind of panel?
Have you tried to check your page with tidy validator? ;)
You believe that divs inside a element is normal?
