Sincerly, Celine Hi,

I am pulling an XML file from a server, and i want to serialise the”tw:twproject” into TwprojectVO, but i don’t know which types of properties i can make in the TwprojectVO class. here is an example of my XML file which can change(not static):

can you give me an idea.

With AIR you can save any ActionScript object to a file. You can save anything from simple objects to arrays of value objects. However there is a catch: when the object you stored has a type (let’s say for example VOPerson), then  when you retrieve it is safe to cast to the original type. But if you save an ArrayCollection of VOPerson, then when you retrieve them you will have an ArrayCollection of Objects. More on this here.

Thus, when you do: temp = item; you get the warning because the two variables have different types. I wrote an article on saving ArrayCollection to disk in AIR. And what is happening, is that the type of the items is lost when you read the array from disk. You could use my function I am giving in this post. By the way, you can see for yourself what is happening if you launch the project in debug mode and you place a break point where you assign the item to the temp.

One question...i'm not pulling an XML file from a server...i have an ArrayCollection which is saved to the desktop which acts as the dataprovider for my datagrid. I have modified the serialToVO function b/c i'm not working with any XML...all i did was remove the 2nd for loop...but i keep getting an error...any advice would be great. Thanks. private function serialToVo (collection:Object, claz:Class):ArrayCollection { var arr:ArrayCollection = new ArrayCollection(); for each (var item:Object in collection) { var temp:Object = new claz() temp = item; arr.addItem(temp); } Mihai, thanks for the tute.

But, what I found while working on Flex applications that grows and need maintenance is that is more simple and cleaner to work with typed objects instead of proxy objects. That is to wrap the data rows in an value object class. Thus I can beneffit of Flex Builder code completion and compile time errors. Well ideally it would be to send the data from server directly as AS objects (using remoteing and AMF).
