How to override a Plone event subscriber
overriding, plone
Solution
When you specified the overrides.zcml, you also need to register the zcml override in buildout? Take a look at: http://developer.plone.org/components/zcml.html?highlight=zcml#overrides It'd be something like: zcml = my.package-overrides
Additionally, you can try using the z3c.unconfigure package: http://pypi.python.org/pypi/z3c.unconfigure
Problem
I need to extend a Plone product (Products.Poi) with a second product. In the extension product i need to override a subscriber event of the original. I tried to subscribe in an override.zcml an event with the same name but the second event don't override the first but all two are execute. Here http://plone.org/products/dexterity/documentation/manual/five.grok/core-components/events seem that is not possible: Unlike adapters, you cannot override an event subscriber by using a more specific interface. Each and every applicable event subscriber will be executed when an event is fired. Someone has a trick? Thanks Alex
