Hi All,

How to read the children data from the ArrayCollection at the java end.

Explanation:

I have an ArrayCollection with children and I am passing this as a
dataprovider to the ADG (as HierarchicalData).


private var dpHierarchy:ArrayCollection = new ArrayCollection([
{Region:"Southwest", children: [
{Region:"Arizona", children: [
{Territory_Rep:"Barbara Jennings", Actual:38865, Estimate:40000},
{Territory_Rep:"Dana Binn", Actual:29885, Estimate:30000}]},
{Region:"Central California", children: [
{Territory_Rep:"Joe Smith", Actual:29134, Estimate:30000}]},
{Region:"Nevada", children: [
{Territory_Rep:"Bethany Pittman", Actual:52888, Estimate:45000}]},
{Region:"Northern California", children: [
{Territory_Rep:"Lauren Ipsum", Actual:38805, Estimate:40000},
{Territory_Rep:"T.R. Smith", Actual:55498, Estimate:40000}]},
{Region:"Southern California", children: [
{Territory_Rep:"Alice Treu", Actual:44985, Estimate:45000},
{Territory_Rep:"Jane Grove", Actual:44913, Estimate:45000}]}
]}


And I am passing this ArrayCollection to the Java method. I did not find any
method to read the children from the ArrayCollection.

And also, How to convert HierarchicalData type to Java.

Please help me to resolve this issue.

Thanks,
Giri

Hi,

If you are using Remoting of BlazeDS to invoke the Java method from Flex,
ArrayCollection will be converted to ArrayList on the Java side. The ArrayList
will contain the Objects you are passing. In your case as you are not mapping
your objects to the Java classes, the objects will be received as objects of
the type Object to the Java method.

Hope this helps.

Hi,

You can find details on how to map AS objects to Java objects at the URL
below.
