Hello,

There is actually problems with drools 5.3 and jbpm 5.2. We get errors like:

 ERROR context.GrailsContextLoader  - Error executing bootstraps: Error creating bean with name 'transactionManagerPostProcessor': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Invocation of init method failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.codehaus.groovy.grails.orm.hibernate.cfg.GrailsAnnotationConfiguration]: Constructor threw exception; nested exception is java.lang.NoSuchFieldError: INSTANCE

I have tried to run drools-gorm example and plugin validation tests and get the same error on 2.1.0 of grails.
Note that I had to exclude hibernate-annotations to get the app to run.
Any idea why this would be happening?
The tests all successfully pass in 1.3.9 not sure why this is failing.

I'm try to run Drools Gorm under Grails 1.3.7 + Java 1.7 64 bits and one error appears when i try to run-app :
Dialect error 1.7

I am getting some errors trying to install the plugins for grails 2.2:

drools-gorm;0.5.6: java.text.ParseException: inconsistent module descriptor file found in 'http://grails.org/plugins/grails-drools-gorm/tags/RELEASE_0_5_6/drools-gorm-0.5.6.pom': bad organisation: expected='' found='org.grails.plugins';

Does anyone know how to resolve this in Grails 2.2

According to the 'Secure Data Binding With Grails' post http://spring.io/blog/2012/03/28/secure-data-binding-with-grails/ transients properties of Domain classes doesn't take part in constructors of class. So this plugin doesn't work in Grails> 2.0.2. What is the best way to resolve it?
