When using Struts-menu 2.3, I created my own version of the
VelocityMenuDisplayer and removed the code to disallow menu components
based on user role - instead, I handle the display of what is allowed for
each user role directly in Velocity using:
#if ($displayer.isAllowed($menu))
This has the advantage of not resetting the application scope menu each
time a user with a different role logs in.
I can do this again for Struts-menu 2.4 by creating my own
VelocityMenuDisplayer class once more and removing the call to:
updateAllowedComponents(menu);
However, in Struts-menu 2.4 it seems that Velocity is only initialised if I
use the supplied
net.sf.navigator.displayer.VelocityMenuDisplayer
Code in:
net.sf.navigator.menu.MenuRepository
specifically checks for this particular displayer:
if (displayerMapping.getType().equals(VelocityMenuDisplayer.class
.getName())) {
if (servletContext == null) {
log.error("ServletContext not set - can't initialize
Velocity");
} else {
VelocityMenuDisplayer.initialize(servletContext);
}
}
It's reasonable that we only want to initialise this once, but tying it to
a specific displayer type seems a bit restrictive.
