I am using a grid panel which gets its data from a php file on the server via JSON. Therfore I crated a HttpProxy (proxy: new Ext.data.HttpProxy({ url:...). Works fine.
My problem is the way back. When my handler calls the remove function of my datastore, EXT is calling my HttpProxy URL automatically. Via Firebug I can see that this happens with POST method and with some JSON code. Unfortunately I don't know how to process this data in my php file since the $_POST variable is empty. I couldn't find any examples.
