SiteMapNode.AddNode() "...is not a valid virtual path." error.

[Dheeraj]

I just started using customized SiteMapProvider inherited from
StaticSiteMapProvider and overriding BuildSiteMap().

I want to use this Provider to be source to a treeview. I want one of
those links to be a javascript link, like:

"Alert Me" should alert a javascript Alert.

Can anyone please help me how do I insert a Node with javascript link
in it.

I appreciate your help.

Thanks
