[Dynapi-Help] Extending DynDocument

[Mani D. <MDo...@SE...>]

Hi all,
I am able to extend the DynLayer into a different class
and intialize that class. But i am not able to extend the
DynDocument. something like this,

function Workbench(session, frame)
{
	this.mSession = session;
	
	this.mDynDocument = DynDocument;
	this.mDynDocument(frame);
}
Workbench.prototype = DynDocument.prototype;

Browser throws an error saying "'document' is null or not an object".
BTW, Can some one send me some tutorials from RichardInfo.com or other
dynapi sites, if somebody has them downloaded. no site in the Most 
Visited Links seem to work. Any suggestion would be of great help.

thanks in advance,
mani
