Yeah, it looks like this error occurs when you have an association tag for a property (in this case a one-to-many or many-to-many) and there is no corresponding property on the Java class which is getting serialized back from the client. Unfortunately the diagnostics for that error don't tell you the destination or the property (which I just fixed in the code) but if you turn the debug log on, you'll see what items are being modified in the batch and can probably figure it out from that.

I am getting a fairly consistent error in my logs... [Flex] 01/28/2008 10:56:06.277 [ERROR] [Service.Data.General] Failed to create collection property: null It doesn't seem to be crashing things, but i figure it can't be good. My only thought is that this could be caused by some transient properties that are in some classes, but are referenced in my destinations. This was our way around the lack of inheritance in 2.5.1 destinations, but perhaps we have caused problems with this. I would be interested in how I could dig deeper into what is causing this error.
