Make TouchKit more push-aware

Currently when using push, touchkit might get confused as to whether the connection is online or offline. TouchKit should be made aware of the state of the push connection to behave correctly.

Was this resolved in Vaadin 7.6 + TouchKit 4.1?

Not sure. Most likely when you disable Touchkit's own offline support and use Frameworks offline support, then yes. Don't know what is the case with TK's offline mode on. Any way to verify this?

I have the situation: Wed Feb 10 17:29:17 GMT+200 2016 com.vaadin.addon.touchkit.gwt.client.offlinemode.OfflineModeEntrypoint INFO: Dispatching: SERVER_AVAILABLE -> BAD_RESPONSE flags=false true true

According to: com.vaadin.addon.touchkit.gwt.client.offlinemode.OfflineModeEntrypoint.dispatch() line 259: logger.info("Dispatching: " + lastReason + " -> " + reason

• " flags=" + status.forcedOffline + " "
• status.networkOnline + " " + status.serverReachable); So, status.forcedOffline # false, status.networkOnlinetrue, status.serverReachable = true But my app go offline, because at the end of dispatch() method we have: } else { // Offline cases status.serverReachable = false; goOffline(reason); } Is it correct behavior? If It's just flags and actual status we set from reason, then ok. And one more question, how can I know exactly cause of BAD_RESPONSE? As I see in com.vaadin.addon.touchkit.gwt.client.communication.TouchKitConnectionStateHandler, there are several cases of this reason.
