[grails-dev] Applying actions to controllers with doWithDynamicMethods

Hi,
I'd like to be able to apply an action to the controllers in an application
via a plugin. I've read that in order to do this you've got to define a
get'MyActionName' method on the controller and return a closure from the
method - is this correct?
I've tried this using the follow code:
def doWithDynamicMethods = { ctx ->
application.controllerClasses.each { cClass ->
println "Controller class = $cClass.name"
cClass.metaClass.getHello = { ->
def hello = {
render "Hello"
}
return hello
}
println cClass.metaClass.methods*.name
}
}
When I look at the methods that have been added to the controller I can see
my new getHello method defined, but when I attempt to call the action I get
a 404 - 'The requested resource is not available'.
Can anyone give me any pointers to where I might be going wrong?
Thanks in advance,
rob

Unless something has changed, you can't dynamically add actions
because Grails looks for a real closure property using bean
introspection. Could your plugin not simply provide its own
controller(s) and actions?

Hi Peter,
Thanks for the info.
Yes, my plugin could provide it's own controller(s) and actions. TBH, I was
just exploring the capabilities of the doWith* closures and thought that
this might a simple way to do it.
Cheers,
