Delete methods applied to objects, but Hibernate filter not executing

[mamsterla]

I have a large project in which I would like to apply logical deletes (due to financial integrity issues). I have added the @LogicalDelete annotation to the classes and collections that apply. I can see that the domain objects are altered in the database to include the deleted property. When I call delete() I can see the value in the database change to 1 indicating a successful logical delete.
However it appears that the Hibernate filter is not being used at all. I have turned on SQL logging and I do not see the deleted = 0 appended to any of the queries on my domain classes. I am using criteria queries in controller classes or service classes typically. I have added debugging and I can see that the logicalDeleteHibernateFilter is defined and enabled. I am at a loss to see why the Hibernate filter is not being applied when all else seems to be working.

Env. is Grails 2.3.8
Database is MySQL5

I created a trivial project with a single Domain class and a single Controller with two actions. It shows that the logical delete occurs, but the subsequent list shows the deleted object.

Here is the Domain class - Squid.groovy:

package logicaldeleteproj

import com.nanlabs.grails.plugin.logicaldelete.LogicalDelete

@LogicalDelete
class Squid {

Integer squidCount

static constraints = {
}

}

Here is the Controller class: SquidController.groovy:

package logicaldeleteproj

import grails.converters.JSON

class SquidController {

def index() {
    for(int i = 0; i < 10; i++ ) {
        new Squid(squidCount: i).save()
    }
    def output = [squid: Squid.list(), squidCount: Squid.count()]
    render output as JSON
}

def delete() {
    if (params.del) {
        def deadSquid = Squid.findBySquidCount(params.int("del"))
        deadSquid.delete()
    }
    def output = [squid: Squid.list(), squidCount: Squid.count()]
    render output as JSON
}

}

Just create a fresh project with the standard Grails 2.3.8 grails app-create
Then add:
compile ":logical-delete:0.1"
to the BuildConfig.groovy
Then run and go to the page:
http://localhost:8080/LogicalDeleteProj/Squid
Followed by
http://localhost:8080/LogicalDeleteProj/Squid/delete?del=3

You will see from the dump that the Squid object is present in the Squid.list even though the deleted field is present and set to true.
