Flex ResourceBundle get keys -> `content` doesn't provide key-value pairs any more

Question

I need to access key-value pairs from a properties file, well a substring of the key and the value to be exact, but that shouldn't change anything.

When you check the Adobe docs and help pages such as this one http://help.adobe.com/en_US/Flex/4.0/UsingSDK/WS2db454920e96a9e51e63e3d11c0bf69084-7f2c.html (last paragraph) you can see that Adobe mentions that the ResourceBundle's content property contains key-value pairs from the given bundle.

The ASDoc of the ResourceBundle also says: "The subclass overrides this method to return an Object that contains key-value pairs for the bundle's resources." However, the ASDoc also says that this property applies for Flex 3.

Anyway, the content property (type Object) doesn't seem to store key-value pairs, as I only get the value, not the key though.

I'm kinda lost here, if anyone has some information regarding this, please shoot!

The ASDoc for ResourceBundle says that this class and it's API is available since Flex 3. So the documentation is still valid for Flex 4 and beyond.

Make sure you are using a "for in" loop rather than a "for each" loop. The "for in" loop iterates over the property names of an Object, while the "for each" would iterate over the values.

This code creates a ResourceBundle and iterates over the properties:

var rb:ResourceBundle = new ResourceBundle("en_US", "bundleName");
rb.content["foo"] = "Bar";
rb.content["hello"] = "Howdy!";

for (var key:String in rb.content)
{
    trace("the key is: ", key);
    trace("the value is: ", rb.content[key]);
}

While iterating, each key is stored in the var key and it's value can be retrieved from the content Object using content[key].

In a real application, w/a real resource bundle file, you retrieve the resource bundle from the resource manager (from the docs you linked to):

var rb:ResourceBundle =  ResourceBundle(resourceManager.getResourceBundle("en_US", "RegistrationForm"))

And then you should be able to iterate over it's content as above.
