Which web framework are you using? If it's Struts 2, the manager is
injected via the setXXXManager method in your action. However, it's
only injected when running in the server since the Spring Plugin
facilitates this. For your tests, you should manually call
setXXXManager. The tests generated by AMP should do this for you. If
they don't, it may be a bug.

hi all:
The following code is my model class. Specially, the key property
"regionId" is a String, not a Long type.
When I use "mvn appfuse:gen -Dentity=DRegion " to generate all the
code and
run "mvn integration-test",
there is an Excepion :
java.lang.NullPointerException
at com.huaat.webapp.action.DRegionAction.list(DRegionAction.java:38)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

sun.reflect.NativeMethodAccessorImpl.invoke

Then I check the code DRegionAction.java in line 38: dRegions =
dRegionManager.getAll();
Obviously , the dRegionManager is NULL ! I check every config
files ,
the dRegionManager bean
was added correctly, including in applicationcontext.xml. like
this:
<!--DRegionManager-START-->
<bean id="dRegionManager"
class="org.appfuse.service.impl.GenericManagerImpl" autowire="byName">
<constructor-arg>
<bean
class="org.appfuse.dao.hibernate.GenericDaoHibernate">
<constructor-arg value="com.myproject.model.DRegion"/>
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
</constructor-arg>
</bean>
<!--DRegionManager-END-->
now the question is, why the dRegionManager is not injected in my
DRegionAction ?
and why every thing is ok when the model key property chang to Long,
instead of a String ?
thanks advanced!
