Thought I should bring this to attention since it’s a weird issue and the solution isn’t obvious when googling.
The issue is - In MOSS an Ajax-Partial postback, causes the page to loose its page title. Like shown below
So whats the fix?
Appaprently additional spaces between the <title> and the <asp:ContentPlaceHolder> cause this issue.
The solution is to remove the spaces.
<title id=”onetidTitle”><asp:ContentPlaceHolder id=”PlaceHolderPageTitle” runat=”server”/></title>
