Looks to me, based on the stacktrace, that you have a race condition. Based on the trace, it appears that you are updating an object after receiving data from the server. There are many things that can affect and effect this timing. Many GXT elements, especially older GXT versions, have properties that can not be modified until the element is attached the first time. So if the data comes back before the elements are attached and you attempt to update the widgets, this kind of thing can happen. That is the best I can say without looking at the code in question.
