MonoTouch: Calling UIWebView.LoadHTMLString Once Web Page is Loaded

When a UIWebView contains an external web site using LoadRequest, then the LoadHtmlString() is called, you get this error. Is there a way around this?

It's hard to be sure without seeing some sample code but since UIWebView.LoadRequest is not reentrant you should take care to ensure LoadHtmlStringis not called until the request has finished loading (they likely share some logic and potentially the same limitation).

My own sample did that (instinctively since I learned the reentrancy limitation recently) and works without any issue.
