Passing complex object from JavaScript to Flex

Question

Is it possible to call a Flex function (defined with ExternalInterface.addCallback) and pass a complex object from Javascript?  The properties of the object are all simple types, but the object itself is an array of objects.  For example:
<script type="text/javascript">
var arrayOfObj = [ { one: "one", two: 2, three: "blah" }, { one: "xyz", two: "abc", three: 3.141 } ];
callSomeFunctionInFlex(arrayOfObj);
</script>
What would I do on the Flex side to make this happen?

Answer 1

Complex object passing works as expected in Blazeds. 
There are certain cases where you need to write custom bean proxy classes to marshall an object, but your case is very simple and will not require it.
Make sure that you set the full java package and class name in your remote alias statement on your client value object.  The class has to be fully qualified.  The AS value object also needs the correct import of the nested value object or you will get a compile error.
Make sure that the blazeds server has the full class path set to your java objects.
To debug, you can turn on Blazeds logging in the services-config.xml file like this:
   <logging>
        <!-- You may also use flex.messaging.log.ServletLogTarget -->
        <target class="flex.messaging.log.ConsoleTarget" level="DEBUG">
            <properties>
                <prefix>[BlazeDS]</prefix>
                <includeDate>false</includeDate>
                <includeTime>false</includeTime>
                <includeLevel>true</includeLevel>
                <includeCategory>false</includeCategory>
            </properties>
        </target>
    </logging>
