Blank on Facebook Feed Dialog

[sidestepper]

Hello, I've been trying to use this to implement Facebook to a mobile app. Authorizing the user through the Auth dialog worked just fine - but I keep getting a blank screen when I try to display the Feed dialog. The same URL generated and dropped into a browser does seem to work. I am going to continue looking to see if it is a Facebook security issue of some sort, but was curious if possibly the page was just not being rendered correctly - what are some of the limitations of the web view if any?

Feed Dialog URL is generated as: http://m.facebook.com/dialog/feed?access_token={Access Token}&app_id={App ID}&from={Authroized User}&to={Selected Friend ID}&link={Post Link}&name={Post Name}& description={Post Description}&redirect_uri={My Redirect Page.aspx}

Thanks in advance for any assistance

Was tearing my hair out about this, but got to the bottom of it - this can be closed. The issue was using spaces in some of the parameters. Guess it's one of those cases where escaping the URL really is important - but if anyone runs into this don't escape the entire URL, just the parameters that get sent.
