Leaking PropertyModel

Hi,

I am finding that the dispose method of the property model either doesn't get called at all, or gets called sporadically, and I end up with an ever increasing number of propertymodels in memory (they do get disposed upon application shutdown).  Furthermore, upon adding an item to a collection, property models are added for all existing items in the collection in addition to the new add, giving an exponential increase in property models when you have a grid with constantly changing high count collections.

Sample that reproduces this behavior will be sent to support e-mail shortly.

Thanks,

D'Arcy
