Re: How to get "id" of the new inserted row, issued by RequestFactory "persist()"

I found the answer here http://groups.google.com/group/google-web-toolkit/msg/fa25840137b26e72:

But I'm still not sure I get the concept. If I use this way I can
access the persisted object in the onSuccess(...) method. But
EntityProxyChange UPDATE will fire *before* the Receiver gets the
result from the server.

I want to put the received task in a list and update a CellList. The
perfect way would be to put an add(Object) method in the Receiver and
some kind of setData() in EntityProxyChange UPDATE. But that won't
work because the data would be set *before* the persisted object has
been put in the list.

Its also not possible to move add(Object) to EntityProxyChange UPDATE
because you only have the ProxyId in there and would have to make
another request to the server in order to get the populated object.
