Have you tried using a StateObjectFactory?

Subject: Re: ASO and hivemind.xml
The situation is :
I create class that extends ApplicationServlet and I specify it as the
tapestry main servlet in web.xml. In this class I call a class that
initialise some "application objects" such as list of element common to
everybody from the database.
My class also set a bean member and implement the get/set method.
I also specified this class as an ASO as you told me to do Geoff and I put
the inject tag in my Home.page.
At the loading of the application, my "application object" is loaded
normally and contains all the list.
When I call the Home.page, the inject seems to work and the pageBeginRender
is called normally. I call getMyASO() I declared abstract, but when I try to
get the "application object" it is null!!
I think Tapestry recreate an instance of MyASO instead of directly get the
first loaded :
web.xml
...
<servlet>
<servlet-name>dm</servlet-name>
<display-name>DM Initialization servlet</display-name>
<servlet-class>dgt.dm.controller.DossierManagerApplication
</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>
...
hivemodule.xml
<?xml version="1.0" encoding="UTF-8"?>
<module id="dgt.dm.controller" version="06.02.01" package="dgt.dm.controller
">
<contribution configuration-id="tapestry.state.ApplicationObjects">
<state-object name="dossierManagerApplication" scope="application">
<create-instance class="dgt.dm.controller.DossierManagerApplication"/>
</state-object>
</contribution>
</module>
DossierManagerApplication.java
public class DossierManagerApplication extends ApplicationServlet {
private ApplicationSettings appSettings = null;
public ApplicationSettings getAppSettings() { return appSettings; }
public void setAppSettings(ApplicationSettings appSettings) {
this.appSettings = appSettings; }
private InitServlet is = null;
public void init(ServletConfig arg0) throws ServletException {
super.init(arg0);
String webRootPath = getServletContext().getRealPath("/");
is = new InitServlet();
is.init(webRootPath);
appSettings = is.getAppSettings();
// NOT NULL WHEN I DEBUG
}
...
HomePage.page
...
<page-specification class="dgt.dm.pages.HomePage">
<inject property="dossierManagerApplication" type="state"
object="dossierManagerApplication"/>
</page-specification>
HomePage.java
public abstract DossierManagerApplication getDossierManagerApplication();
public abstract void
setDossierManagerApplication(DossierManagerApplication
dossierManagerApplication);
public void pageBeginRender(PageEvent event) {
DossierManagerApplication dossierManagerApplication =
getDossierManagerApplication();
ApplicationSettings appSettings =
dossierManagerApplication.getAppSettings();
// IS NULL
setRequesters(appSettings.getRequesters());
setLanguages(appSettings.getLanguages());
}
Thanks for help...
