After six months with the application running without a single change the \[code\]OnSelectedIndexChanged\[/code\] method is not being run any more.\[code\]<asp:RadioButtonList ID="RBL_Comentario" runat="server" Visible="False" OnSelectedIndexChanged="RBL_ComentariSIC" AutoPostBack="true" CssClass="naoimprime"> <asp:ListItem Value="http://stackoverflow.com/questions/14073152/homologar">Obfuscated</asp:ListItem> <asp:ListItem Value="http://stackoverflow.com/questions/14073152/retornar">Obfuscated</asp:ListItem></asp:RadioButtonList>\[/code\]The visibility is later turned on and works as expected. When I check one of the buttons the page is posted but the method is not run. I can see in Firebug the \[code\]__doPostBack\[/code\] running with the correct \[code\]eventTarget\[/code\] just before submitting:
But the RadioButton element is not posted:
I tried IE8, IE9 and Firefox 10. Any hints? What could prevent the html element from being posted? I was thinking about some change in the anti virus software but don't know how to debug that as I can't disable it.
