Hi,
I am using Wildfly 8.1 and Vaadin 7.3.beta1.
I am starting an EntityManager in a @WebFilter and managing the transaction at that layer, that is folowing the entitymanager-per-request pattern recommended for the usage of the JPAContainer addon.
Before Vaadin 7 it was clear to me that for every event in the browser that had a listener in the server a simple HTTP Request will be made and it will go through my Filter, thus initiating a transaction before vaadin code gets executed, and properly finishing that entitymanager transaction after vaadin code executed.
But I am concernet now that Vaadin 7 supports push and might use websocket under the hood that my Filter might not allways be executed.
Will my filter run regardless of the transport being used when using @Push in the UI?
How does this work in Vaadin 7?
Thanks
