Application-context messaging

[Thibault]

Hello,

I'm developping a flex program for android. Our company allready has a flex program for desktop. So I can easily use some pieces of that code.

But I have a small problem with this:
In my application-context.xml I want to add messaging in the top of the file.
like this:

<objects xmlns="http://www.springactionscript.org/schema/objects"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns:messaging="http://www.springactionscript.org/schema/messaging"
         xsi:schemaLocation="
        http://www.springactionscript.org/schema/objects http://www.pranaframework.org/schema/objects/spring-actionscript-objects-1.0.xsd
        http://www.springactionscript.org/schema/messaging http://www.pranaframework.org/schema/messaging/spring-actionscript-messaging-1.0.xsd">

When I now want to run my program I get this error:

Error: No namespace handler found for node '' with URI 'http://www.springactionscript.org/schema/messaging'
	at org.springextensions.actionscript.ioc.factory.xml.parser.support::XMLObjectDefinitionsParser/parseCustomNode()[C:\projects\se-springactionscript-as\spring-actionscript-core\src\main\actionscript\org\springextensions\actionscript\ioc\factory\xml\parser\support\XMLObjectDefinitionsParser.as:357]

	at flash.net::URLLoader/onComplete()

Does somebody know why I can't use this for my mobile development?

Kind regards,

Hey Thibault,

are you sure that the actual XML in your configuration is valid? We haven't done any testing yet with the new Mobile functions of the SDK, so this might indeed be a bug related to that. But looking at the error message it seems as if a node without a name has been encountered.
Can you show us the full XML config, just to make sure?

cheers,

Roland

Hello,

Well I didn't had that fault before I added messaging, so I don't think there is a fault in my XML.

Here you can see the full XML:

I've done some testing to:
First test : only objects en nothing else
Second test : object with the first object
Third text : objects and only the messaging blocks

In this 3 cases I got this error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Hope this helps. And thank you for the help!

Figured it out. You need to add a namespacehandler for the messaging context

applicationContext.addNamespaceHandler(new MessagingNamespaceHandler());
