The Plugin Broker (Zend_Controller_Plugin_Broker) _should_ catch any
exceptions thrown by controller plugins. Well, not should, it does.
Perhaps this is an issue with how you're instantiating your plugins??

Thanks for the run down. Is it possible to throw an error in a plugin though?
So far the errorController has missed it.

if you are not allowed to view the page. I then want to handle that
exception via the errorController. I can wrap the $front->dispatch() in a
try / catch and catch the exception in the bootstrap, but then how do I
forward that onto the errorController, as the front controller has not
been
dispatched? I've read the manual and other posts and have not found an
answer nor an alternative method.
I think you may be misunderstanding the dispatching process of the front
controller. Here's a run down:
1. Request/Response/Router/Dispatcher initialization
2. routeStartup()
* call plugins registered with this hook
3. Routing
* Updates Request object based on matched information from
routing
4. routeShutdown()
* call plugins registered with this hook
5. dispatchLoopStartup()
* call plugins registered with this hook
6. preDispatch()
* call plugins registered with this hook
7. Dispatch action
8. action helper preDispatch()
9. action controller preDispatch()
10. action method
* UNLESS a _forward() or redirect has occurred
11. action controller postDispatch()
12. action helper postDispatch()
13. postDispatch()
* call plugins registered with this hook
/* repeat 6 - 13 as necessary */
14. dispatchLoopShutdown()
* call plugins registered with this hook
15. send response
The preDispatch hooks of action helpers and action controllers ad re
steps 8 and 9, respectively. The ErrorHandler front controller plugin is
registered basically right away.
In short, if you throw an exception in the preDispatch of a
controller/action it _will_ be caught by the ErrorHandler plugin, and
thus forwarded to the error controller.
