is there any way to get referral group info from core messages widget

Most permission denied errors are shown directly and are not redirected via HTTP on the client side. You should be able to inspect $core_v2_page.Url to determine the current group in most cases.

HI Ben,

 $core_v2_page.ReturnUrl is giving " /msgs?MessageID=31: instead of the group. 

scenario is if user clicks add post link on a public open membership group, if user is not the member of the group Telligent core messages will come as access denied. 

Over on core messages widget if we look for $core_v2_page is referring to root instead of the group

In this case, a server-side redirect is used, so it appears that $core_v2_page.Url is also updated from its original value. It appears that this context is not available/persisted through the URL.

A potential work-around would be to set a cookie for the last-accessed group as the user navigates the site and read this cookie on the error page to implement your logic. This would normally have the correct value and would be subject to the same issues with reading URL values to detect the source context.
