[Aerogear-users] Qustions about Push and Cordova

Hello I am trying to get started with Cordova and Aerogear push. When I try to run a simple cordova app I get the following: !JavaScript ERROR: Plugin PushPlugin.messageChannel is not supported !JavaScript ERROR: Plugin PushPlugin.register is not supported How then do you test that the push is working? Second question - apologies if this sounds dumb - am completely new to mobile. Can a push message contain json or xml, or does it have to be simple text? Thanks Anton
