IOS registered file/MIME type - not working on new VM

[GoogleCodeExporter]

Using the old VM and a registered MIME type I am able to get a file URL via 
Display.getInstance().getProperty("AppArg", null). Now under IOS and the new VM 
it returns null.

Steve, can you evaluate this? 
Its based around this functionality:

Need more info.  I followed the instructions on this blog post to add a custom 
URL to my app:
http://www.codenameone.com/blog/intercepting-urls-on-ios-android

My ios.plistInject build hint was:
<key>CFBundleURLTypes</key>     <array>         <dict>             
<key>CFBundleURLName</key>             <string>com.codename1.issue1156</string> 
        </dict>         <dict>             <key>CFBundleURLSchemes</key>        
     <array>                 <string>myapp</string>             </array>        
 </dict>     </array>

I have attached my test case.

If I open the app cold by entering a url like myapp://ggg in safari, it 
correctly reports the URL in the AppArg property.  If the app is already 
running in the background, and I open a URL in Safari, the start() method is 
not called, but I can click the button to see that the AppArg has been applied 
correctly.

Please provide a test case.  I'll reopen this issue when one is received.

I really do not know what to give as a test case. This is very simple.

<key>CFBundleDocumentTypes</key>
    <array>
        <dict>
            <key>CFBundleTypeName</key>
                <string>MyApp MyFile</string>
            <key>LSHandlerRank</key>
                <string>Owner</string>
            <key>CFBundleTypeRole</key>
                <string>Editor</string>
            <key>CFBundleTypeIconFiles</key>
                <array>
                    <string>myfile.png</string>
                </array>
            <key>LSItemContentTypes</key>
                <array>
                    <string>de.sae.test.myfile</string>
                </array>
        </dict>
    </array>
<key>UTExportedTypeDeclarations</key>
    <array>
        <dict>
            <key>UTTypeDescription</key>
                <string>MyApp MyFile</string>
            <key>UTTypeConformsTo</key>
                <array>
                    <string>public.data</string>
                </array>
            <key>UTTypeIdentifier</key>
                <string>de.sae.test.myfile</string>
            <key>UTTypeTagSpecification</key>
                <dict>
                    <key>public.filename-extension</key>
                        <string>myfile</string>
                    <key>public.mime-type</key>
                        <string>application/myfile</string>
                </dict>
        </dict>
    </array>

I did another test - by opening my file in Apples mail apü. The funny thing is 
- it works if the app ist started anew. Then the start() method is called and 
Display.getInstance().getProperty("AppArg", null) delivers the right thing. If 
one then opens the file again the app is opened, the start() method is called - 
but Display.getInstance().getProperty("AppArg", null) gives the old value, 
whatever it was before.
Which consecutive file openings it works well.
I tested it. It is always the second time after restart of the app where 
Display.getInstance().getProperty("AppArg", null) fails to give the file that 
was opened. Any idias on that?

It looks like I was testing something different  (custom URL schemes).    For 
your test case, please also post some code showing how/when you are checking 
for "AppArg".

Sorry that was my fault, I assumed this would be identical.

I see the problem.  The start() method is called before the URL callback 
occurs, so when you check the AppArg at the beginning of your start() method, 
it hasn't been set yet.   You can verify this by adding some sort of delayed 
action (e.g. through a Button action event) to be able to check the AppArg at 
will, and you'll see that it actually does get set even when the app was just 
being loaded from the background.  

The correct way to detect the loading of a file/URL is to implement the 
URLCallback interface.  See the test case I have attached for an example.

Steve, I'm not sure the URLCallbackInterface is the way to go since the 
behavior here is iOS specific. Unfortunately I can't think of a decent way to 
solve this because of the race condition where the app is launched and the 
callback is sent later.

The behavior on IOS and on Android is very different. It would be nice to have 
a description of how to handle this on both platforms.

There is also an issue under Android - see
