Vaadin Applet integration out of sync problem

Flow
1

Hi, I followed the link
here

In my applet, I extend AbstractVaadinApplet class and code:

  vaadinUpdateVariable("mydata", "somevalue", true);

In server part, I inherit the AppletIntegration class and override changeVariables() method :

@Override
    public void changeVariables(Object source, Map variables) {
        super.changeVariables(source, variables);
        if (variables.containsKey("mydata")) {
            String mydata = (String) variables.get("mydata");
        }
    }

However, when I call vaadinUpdateVariable() method, it results a “out of sync” problem showing on the Vaadin webpage. I have tried to use vaadinSync() method as well, but no luck.

Could you help me on this issue? Many thanks!

I do not get it, have the same issue. Can you explain the solution to me please?
The link above just links to the beginning of a huge forum entry, so I don’t know what exact post you mean!?!

Thanks!
