Hi,
I am trying to follow the server push guide at:
http://zkoss.org/smalltalks/zk3.0rc/zk3.0rc.dsp

In a zscript file (included from a zul page), I am calling a new Thread (class from the guide):

desktop.enableServerPush(true);
MyThread thread = new MyThread(hbox);
mythread.start();

In my Thread class, I get the following error, however

Exception in thread "Thread-35" java.lang.IllegalStateException: Components can be accessed only in event listener

This also happens when trying to run the demo on that same web page. Am I doing something out of order/wrong? I run Executions.activate(_desktop) from within the 'MyThread' class.

Thanks,
Brendan

Sorry, i'm new to ZK - I'm not sure what you mean? Is there a possible issue with the code I posted above? I enabled server push on the desktop before calling
start() on the new thread, as I have seen in many examples, but it still throws that error, whether with the demo code or my code.

Thanks,
B

Hi Brendan,

Please make sure you don't do any modification to ZK components after invoking Executions.deactivate(_desktop); //you cannot access ZK components from now on

And take a look at this example,
