[CLOSED] WebService Proxy crashes when I try to pass a Hidden field for <AutoLoadParams>
When I used the code below for the <AutoLoadParams> it works because I get the value of '6' in my Handler.ashx page.
ERROR: "Microsoft JScript runtime error: 'App.hdLineId' is null or not an object"
.aspx
.Handler.ashx
<AutoLoadParams>
<ext:Parameter Name="lineID" Value="6" Mode="Raw" />
