I tried changing StringType to int. did nothing. This confuses me a little. The properties of the object can be modified and keeps their state on the client. but all changes are lost on the server. since it is stateless one would think that the "original" values also would be lost, and why isnt the client object values passed to the server for method invocation. thank god for Apress Books and vacation coming up :) Anyway, i solved this by having a local class with the same properties and my custom ToString. If it' stuck, DO NOT pull harder!

Yes, you will need to create a copy of the list yourself. While, List<T> does not implement ICloneable, ArrayList does. But even so, it's only a swallow copy. Take care, Tom ----------------------------------------------- Check out my blog at http://tjoe.wordpress.com
