Here is what I did to resolve it...
you can include your static link to the javascript if you like, just follow it with another script tag as such (mind the spaces, have to do that so the forum allows it)
<s cript type="text/javascript">jQuery.noConflict();</sc ript>
This will force jQuery to return the $ back to the "original" library and you will need to use a direct jQuery reference from here on out.
Alternatively, set it through code (again, mind the weird spaces I've inserted so the forum allows it):
protected override void OnPreRender(EventArgs e)
{
if (!Page.ClientScript.IsClientScriptIncludeRegistered("jQueryScripts"))
Page.ClientScript.RegisterClientScriptInclude("jQueryScripts", "http://localhost/dnndev/desktopmodules/someModule/includes/jquery-1.2.3.min.js");
if (!Page.ClientScript.IsClientScriptBlockRegistered("jQueryConflictMode"))
{
StringBuilder script = new StringBuilder();
script.AppendLine("<s cript type=\"text/javascript\" language=\"javascript\">");
script.AppendLine("jQuery.noConflict();");
script.Append("</sc ript>");
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "jQueryConflictMode", script.ToString());
}
}
