It's a bug; the API shouldn't be throwing exceptions. Please file a bug at http://bugs.webkit.org.

Hi,

When I call the following method:

[dataSource subresources]

from inside the following method:

- (id)webView:(WebView *)sender identifierForInitialRequest: (NSURLRequest *)request fromDataSource:(WebDataSource *)dataSource

of my WebResourceLoadDelegate, I get the following error (the error occurs for 98 out of 105 calls to the previous method for a specific webpage):

*** WebKit discarded an uncaught exception in the webView:identifierForInitialRequest:fromDataSource: delegate: <NSInvalidArgumentException> *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil

Is this normal because I'm not supposed to ask for the subresources until everything is loaded? Or is it a bug?

Many thanks,
Martin.
