My main WebView's method for opening windows is controlled via

Why create a second WebView? Just make the decision in your main
WebView using the WebPolicyDelegate method
-webView:decidePolicyForNavigationAction:request:frame:decisionListener:
and send the listener an -ignore message (from
WebPolicyDecisionListener protocol) if you decide to open the link in
an external browser.
Here's an example:
// <WebPolicyDelegate>
// if the user clicks a link it loads the url in an external web
browser
// if a page is loaded progammatically (via loadHTMLString:baseURL:
for example) then that link is opened by the WebView
- (void)webView:(WebView *)sender decidePolicyForNavigationAction:
(NSDictionary *)actionInformation request:(NSURLRequest *)request
frame:(WebFrame *)frame decisionListener:(id
<WebPolicyDecisionListener>)listener
{
if ([[actionInformation objectForKey:WebActionNavigationTypeKey]
intValue] != WebNavigationTypeOther) {
[listener ignore];
[[NSWorkspace sharedWorkspace] openURL:[request URL]];
}
else
[listener use];
}
If you only want to use the external browser when the user tries to
open a new window use
webView:decidePolicyForNewWindowAction:request:newFrameName:decisionListener
: instead.
