Can't use the application: PushAtmosphereHandler onStateChange (7.5.5)

Jon Inazio Sánchez Martínez
7 years ago Sep 15, 2015 7:56am

I'm testing charts on vaadin and I've recently developed a brand-new application using vaadin 7.5.5 and several add-ons.

Today, I'm facing a problem which prevents me from using the application itself. In Google Chrome, after typing credentials within my login form, the application starts loading something I don't know (without pressing any key or button).

Looking my logs, I've realised that something unknown happens (which shouldn't happen). I attach the whole log, but the problem remain on the bottom:

After cleaning cachè and commenting Async and Push mode:

<!--         <init-param> -->
<!--             <param-name>pushmode</param-name> -->
<!--             <param-value>manual</param-value> -->
<!--         </init-param> -->
<!--         <async-supported>true</async-supported> -->

Now works... But perhaps I'll be needing it...
