Hello, My service has got a webmethod with an object as param. This object contains an array of another object, which contains an array of another object, which contains 2 attributes. The service receives the first object with his array, but the array is full of null objets. At the client side, no object is null. I don't understand. Any idea ? Is there a limit of depth ? Thank you. Fred. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4044412#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
