I am using GWT-RPC to populate Ext-GWT TreeGrids with data from a server. I am using 4 callbacks to populate 6 TreeGrids. As the callback onSuccess function modifies the TreeGrid by inserting rows, the TreeGridView needs to render the rows. The callback class is called MainPnlSummaryTablesAsyncCallback.
For some reason, when it needs to determine the TreeGridView's scroller's offsetHeight via JSNI, onSuccess or onFailure is called on another instance of the callback in the stack trace. A copy of the stack trace I encountered is below. Isn't this really weird? Why is this happening? FYI I am using Ext-GWT 2.0.1 and GWT 1.7.0 and I am using hosted mode browser to debug this, although I am pretty sure that this is an issue for web mode.
