I do this in the beforeRenderTemplate(),and works fine!
boolean beforeRenderTemplate() throws IOException, ServletException {
if (!isLogined()) {
if (appState == null) {
appState = new AppState();
}
appState.setErrCode("00100");
appState.setPrePage("index");
global.getResponse().sendRedirect(
global.getHTTPServletRequest().getContextPath()
+ "/errorMessage");
}
return true;
}

No, I'm pretty sure you can't.
Read the documentation again, and look at:
ComponentPageElementImpl.RenderPhaseEventHandler.handleResult()
It seems to confirm that returning a component will render that
component and then _continue_ with the rendering phases for the
current component.
Render phase methods are completely separate from the event handlers
for page navigation events. All options are on the page I linked to:
http://tapestry.apache.org/tapestry5/tapestry-core/guide/pagenav.html
Cheers,
Nick.
