Here is the code in my widget plugin:

-(id)initWithWebView:(WebView*)w {
	NSLog(@"Entering -initWithWebView:%@", w);
	[w setFrameLoadDelegate:self];
	self = [super init];
	return self;
}


This is not a good thing to do.

Taking over as the frame load delegate for the WebView you're inside is an inappropriate thing for a plug-in to do. Those APIs are for the object creating the WebView. As a plug-in implementer just a visitor in someone else's WebView (DashboardClient's, to be specific), so you should not overwrite the delegate with your own.

As a plug-in, you are already able to get at the host page's window object at the moment you're created. So even if wasn't a bad idea, it's too late to hook up a frame load delegate, the "window object available" message has already been sent.
