Re: [flexcoders] [CUSTOM COLLECTION SERIALIZATION - BLAZEDS]
Hi Seth, Thanks for the quick reply Seems like the problem was a bug with BlazeDS. Like I mentioned, the custom objects inside of the collection (Country for example) are working fine just the custom collection type I created that was not. The did some digging in BlazeDS code and I verified that during serialization they were checking if the given instance was a Collection before Checking if it was Externalizable. On the trunk version of BlazeDS (3.0.1) this is already fixed and Externalizable is the first type checked during serialization. I hope they get 3.0.1 out soon.

Using [RemoteClass] requires that you have a hard dependency on this custom AS collection class in your app in order for mxmlc to generate the necessary registerClassAlias call during Flex app init; if you don't have an explicit variable of this type in your app, just create a dummy variable during startup that is thrown away and gc'ed and it should do the trick.

I'm using BlazeDS. I implemented IExternalizable and Externalizable both ends but I still always get back a ArrayList instead of my custom implementation. The objects inside of the collection are bound correctly, only the collection that remains. Any hints about this? Regards, João

Hi João, You can download the BlazeDS 3.2 release (milestone build) here: http://opensource.adobe.com/wiki/display/blazeds/download+blazeds+3 That should contain the fix you mention.
