Description
For googlemaps this only happens the first time the application tries to load one of it's jspx pages.
For inputRichText, this happens each time.
Note that these pages are within panelTabSet (as per 1.7.0.Beta1 samples/component-showcase --jspx pages are same).
If the TreeNavigationBean is in Session-scope then the pages load properly, but curiously the backing bean for inputRichText is loaded twice.
Looks like some circumventing of the jsf lifecycle and is very noticeable when using standard request scope.
I am trying to create seam-comp-showcase with only the style bean as session-scoped, (and to use to test concurrentDomView=true)...this means that each session can have multiple conversations of seam-comp-showcase. For now, with TreeNavigation in session-scope, each window has to view the same state of the tree (no point to use concurrentDomView=true). Nice also to show that all our components can be used outside of Session scope.

The apparent abnormal behavior is due to the way InputRichText and GoogleMaps components inject their resources (javascript code) into the page. Because the resource references are inserted into the 'head' element of the page ICEfaces will send a 'reload' command to the browser (see ICE-2189 for a that). The references are inserted lazily, only when the component is instantiated the first time.
The first instantiation of InputRichTextBean is done by Seam, but because there's a page load triggered and the bean is page scoped a second instance will be created. The lifecycle is not shortcut, is just that a page load/reload doesn't contain any values that need to be applied so the related lifecycle steps are skipped.
The mentioned components could be refactored to inject their resources when the application starts if we need to avoid this additional page reload.
I have to put the navigation in session scope (or the context gets cleared since I get 2 jsf lifecycles). Curiously, when I put some debugging into phaselistener it shows the following:-

Suggestion:- do same with regular component-showcase first with standard request scope = false and then with standard request scope=true (use jsf1.2 and facelets to make as similar as possible).
