Hello everyone!
I’ve been experiencing problems with every 8.1.x release when using Push.
Already tried both automatic and manual modes, all transport options and still failing.
If I hide a component(Button, Label, TextField, etc) using setVisible(false) method, and the UI.getCurrent.push(), everything works as expected.
On the other hand, if I use setVisible(false) on a Layout, it loses all format when pushed to client and the View has to be refreshed.
Multiple client-side exceptions are shown as well. The main one being:
Error updating connector hierarchy java.lang.IllegalStateException: An extension can not be moved from one parent to another.
Also:
com.vaadin.client.communication.MessageHandler
SEVERE: Error sending hierarchy change events
com.google.gwt.event.shared.UmbrellaException: Exception caught: (TypeError) : ax(...) is null
Caused by: com.google.gwt.core.client.JavaScriptException: (TypeError) : ax(...) is null
No server-side exceptions are thrown.
This works perfectly on 8.0.7
Any ideas?
