beforeInterceptor added from plugin

[ihery]

Hello,

I'd like to add a "pre-action" behavior from a new grails plugin that
would look at all my controllers during startup. However I would like to
avoid extending a base controller (that would define the
beforeInterceptor logic) to keep my controllers untuched.

Here is my question : is it possible in a grails plugin to dynamically
add a "beforeInterceptor" to some actions. Can I use
doWithDynamicMethods for that purpose ?

Thanks,

Probably. The intention is to use Groovy-AOP for this, but as far as I
am aware, no one has tried it yet for this kind of thing. Check it out

I've tried adding afterInterceptors programmatically, and I didn't get
too far. It looks like Grails Controllers are stored as instances of
Spring's BeanWrapper. Since BeanWrapper doesn't know anything about
the metaClass, if an interceptor doesn't exist during compilation, the
BeanWrapper's isReadableProperty() for the interceptor will always be
false.

Check org.codehaus.groovy.grails.commons.DefaultGrailsControllerClass
line 235 to see what's happening there.
