RE: [flexcoders] complex Remote Objects

Hi,
 
Maybe you left it out in your example, but do you have the DataGridColumn tags? Like so:
 
<mx:DataGrid width="436" height="100%">
                <mx:dataProvider>
                    {person.phones}
                </mx:dataProvider>
        <mx:columns>
        <mx:Array>
            <mx:DataGridColumn headerText="number" width="125" labelFunction="zip"/>
            <mx:DataGridColumn headerText="info" width="125" columnName="name1" />
            <mx:DataGridColumn headerText="type" columnName="type" />
        </mx:Array>
        </mx:columns>
</mx:DataGrid>
 
Perhaps you should show us the piece of code that sets the dataProvider of the DataGrid. I think the problem lies there.

Hi Peter,

I still have the problem with my complex Remote Objects. Here is some code and other stuff:

Output:
DataGrid

Implementation in MXML:

                <mx:dataProvider>
                    {person.phones}
                </mx:dataProvider>
           </mx:DataGrid>

Input in person from remote method:

I attached the JavaVOs and the AsVOs as file.

I still don't know why I'm not able to access person.phones (person.addresses doesn't work too ). If I go through person.phones and do if(person.phones[i] instanceof OgoPhoneVO) I get true. 
I tried implicit getters / setters, but this wasn't a real success. As mentioned in "developing rich clients with macromedia flex" on page 470 in the grey box, implicit getters/setters should not be used with RemoteObjects.

After 2 days trying I don't have any more idea. I bet I am making a tiny mistake, but I can't figure out what it is.

If you've used Object.registerClass on both Phones and Person classes there should be no problem with them being returned in an Array (that is, the Flash Player creates the Phones instances during deserialization no matter how deeply nested).

When you say:

"There are objects in ApplicationPerson.phones but it seems the information which type of objects are in it is gone."

How do you test that this type information is lost? You could add a method to the Phones class, such as:

class Phones{
    public var number:String;
    public var info:String;
     
    public function test():String {
        return ("My info is: " + info);
    }
}

Then call .test() on an Array member that is supposed to be of type "Phones" - if the call succeeds then you have an instance of Phones, if not, then perhaps you just have a generic Object.

If the call did succeed, then perhaps you've uncovered a bug (possibly in DataGrid and its interaction with deserialized objects)? Let me know how the test goes and I'll pass on to QA to test.

Subject: [flexcoders] complex Remote Objects

Hi List,

I use some complex Remote Objects. Let me give an example:

class Phones{
    public var number:String;
    public var info:String;
}

class Person{

    public var   name:String;
    public var firstname:String;
    public var phones:Array;

}

These are only example classes. In my app they are more complex and of
course I uses Object.registerClass().

The phones array in the Person class contains some Phones Objects. Let's
say I have a Person object ApplicationPerson in my app and
ApplicationPerson is filled with values by a remote call. There is
absolutely no problem to access ApplicationPerson.name and
ApplicationPerson.firstname, but when I try to fill a DataGrid with
ApplicationPerson.phones nothing is shown. There are objects in
ApplicationPerson.phones but it seems the information which type of
objects are in it is gone.
The only possibility I found to access ApplicationPerson.phones is to
put a getPhones method in the class Person in which I cast every item in
phones. getPhones could look like this:

public function getPhones():Array{
    var ret:Array = new Array();
    for(var i=0; i < phones.length; i++){
        ret.push(Phones(phones[i]);
    }
    return ret;
}

Is a explicit getter-method the onliest chance to deal with complex
Remote Objects or is there a possibility of "deep-cast" Flex does on its
own?
