Is ExtJS4beta2. The circuit such
Ext.grid.GridPanel in it Ext.data.Store to refer on Ext.data.Model in model Ext.data.AjaxProxy with (api) in it Ext.data.JsonReader and Ext.data.JsonWriter.
The similar circuit in an example here.
If I delete a line in GridPanel then it I do Sync() the server answers success:false that Ext with GridPanel deletes the data and in Ext.data.Store isn't present and stores them there in the field Ext.data.Store.removed. How to me to force Ext if the server on request to delete has returned success:false to leave a line in GridPanel?
