second if you really want to you can delegate back to the component. create a subclass of pagelink that implements the strategy and in the general strategy you can forward the security check back to the component.

Hi,
I just started looking at IAuthorizationStrategy and the rest of the
security so i could have overlooked it but here is what i would like
to be able to do.
Specify a security check for each individual component to use (if
there is no check then don't bother). For instance i would like to
check all my pagelinks if they are allowed to go to there destination,
you might say that is easy take a strategy and put an if(component
instanceof PageLink){.......}. But on certain pages that same pagelink
class has to check for example if the user is an administrator, and so
there are several more exceptions to the default behaviour. As far as
i see it i have the following options:
1 use the strategy and build a really big and elaborate series of if statements.
somehow this just doesn't seem right to me.
2 the iactionauthorizer allows me to specify what to do for each
action. allowing me to create lots of actions like 'render A', 'render
B' and so on.
but i would like to use the same action over and over again and i
cannot override the default render action used for rendering.
3 use the metadata facility in component to supply addiotional info i
can then use to check in the strategy.
i would still need to program a lot of if statements in the
strategy, see point 1.
What i would like is the ability to set some sort of security check on
component (which has a similar interface as the strategy) and which
would allow me to do some extra stuff before going to the strategy. Or
just set the strategy on each individual component. The added
advantage of having a strategy per component is that if there is no
strategy apparently nothing needs checked.
Or am i missing something and is what i want already there, or should
i do things differently.
