onClick() called after model is loaded

["Zheng, Xiahong" <Xi...@FMR.COM>]

Is onClick() called during the process of page rendering? My page has
some components with visibility controlled by model attributes. If the
model is loaded before the onClick() method is called, the page will not
render correctly unless I force a reload again to reflect the state
change made by onClick() method. Is it a way to get onClick called
before the page rendering? I also notice the addStateChange method, but
now sure how to use it. Can someone help? Thanks. -XZ

visibility of components is checked before onclick for security
reasons - eg you should not be able to click a link that is not
visible. if you use your model inside isvisible() override it will
potentially get loaded with stale data, you have two options:

1) instead of overriding isvisible() override onbeforerender() and
call setvisible()
2) as the last thing you do in onclick() call detach() on the
component that has isvisible() overridden
