Bug in GORMSessionFactoryDefinitionParser

In GORM of Grails 1.1, I found this bug.
if you define context.xml like this.

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
 <property name="sessionFactory" ref="sessionFactory" />
</bean>
<gorm:sessionFactory base-package="org.grails.samples"
  data-source-ref="dataSource" message-source-ref="messageSource" transaction-manager-ref="txManager">
 <property name="configLocations" value="classpath:hibernate.cfg.xml" />
 <property name="hibernateProperties">
  <util:map>
   <entry key="hibernate.hbm2ddl.auto" value="update" />
  </util:map>
 </property>
</gorm:sessionFactory>

An attribute transaction-manager-ref is not necessary, for Grails will create transactionManager (org.springframework.orm.hibernate3.HibernateTransactionManager), but whether you provide your transaction manager, you will see this exception.

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'transactionManager' is defined

In found in GORMSessionFactoryDefinitionParser on line 213.

   targetRegistry.registerAlias("transactionManager", transactionManagerRef);

I thought this line intend to give transactionManager being an alias of transactionManagerRef.
It should be

   targetRegistry.registerAlias(transactionManagerRef, "transactionManager");

Problem from using JPA in grails with maven

I got this problem when i called $mvn grails:run-app.

It seems javax.persistence does not exist in maven dependencies of grails-maven-archetype 1.0.
To fix this problem, I added ejb3-persistence in pom.xml.

    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>ejb3-persistence</artifactId>
      <version>1.0.2.GA</version>
    </dependency>
