I have an exception (that doesn't affect the overall application behaviour) that I cannot locate exactly in my code and that seems to come from the GXT events system. I'm not sure it is a bug, but it would be good at least to know what does it mean.

No way to give you the context, the page where it happens is huge and there is no information on the point where it happens exactly:

You have a value in your store that has the displayfield data set to null.
