Yeah, I'm using Java 1.4.2 and I just couldn't get the injects in the
.page to inherit.
Following Derick's tip, I came up with this (if it helps anyone else),
which seems to work so far (although I'm not claiming it to be the best
way):
public abstract class Page extends BasePage implements
PageBeginRenderListener
{
private ApplicationStateManager stateManager = null;
public void pageBeginRender(PageEvent event)
{
if (stateManager == null)
stateManager =
event.getRequestCycle().getInfrastructure().getApplicationStateManager()
;
}
public Application getApplication()
{
return (Application) stateManager.get("application");
}
public Session getSession()
{
return (Session) stateManager.get("session");
}
public boolean getSessionExists()
{
return stateManager.exists("session");
}
}
Thanks for the tips!
/dev/mrg
PS. "application" = "global" and "session" = "visit" -- I renamed
everything to make sure I caught omissions/errors.

Subject: Re: Abstract superclass for pages with injection in T4?
ok - it seems you don't use jdk1.5. the .page file does not get
inherited.
The only solution I can see is copy/paste the <inject to all your .page
defs.
