I am using zk ce version 6.5 and i have a problem. My login/index pages is being loaded twice.

when i on logout button call this:

Executions.createComponents("login", center, null);

above page has two fields and i am using MVVM approach.

Now it loads fine, but as soon as i enter the username in the textbox or enter the password in textbox, page is automatically refreshed. I have checked in my code, i am not calling the above method anywhere else in a process here.

Please tell me why on textbox/password textbox i am getting this behaviour for the loginpage. once it's reloaded twice, it gets the username and takes me to home page. now i logout and same scenario.

for two times, i am getting call to this method, once is obvious, bacause on logout i called it, but on entering any text in textbox and removing the focus from it. then this method is again called.

@AfterCompose public void afterCompose(@ContextParam(ContextType.VIEW) Component view){ Selectors.wireComponents(view, this, false); }

I have inspected my code too, there is no event on any of the textfield.

Please have in mind, that most of the people here spend their free time for answers. Without having looked too much into your question, it may help if you simplify the code in a way that somebody can also run it in its own environment.
