EntityManager is closed exception in SeamTest
I'm trying to get some basic CRUD functionality working in my application. I have a simple Entity called Category and a simple controller for it that inherits from EntityController. In my test I keep getting EntityManager is closed exceptions in the second test in my suite. I searched around quite a bit in the forums (both of them) and google without any hints.
Here's the exception:

Here's the controller: (as you can see there's not much to it at this point)
package com.grocery2dinner.actions;
import javax.ejb.Stateless;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Out;
import org.jboss.seam.framework.EntityController;
import com.grocery2dinner.model.Category;
@Stateless
@Name("catManager")
public class CategoryManagerAction extends EntityController implements CategoryManager
{
private static final long serialVersionUID = 1L;
@In(required=false) @Out(required=false)
private Category category;
private long id;
public String delete()
{
remove(category);
return null;
}
public String find()
{
info("Finding Category with ID: " + id);
category = find(Category.class, id);
return null;
}
public String save()
{
persist(category);
return null;
}
public String update()
{
merge(category);
flush();
return null;
}
public long getId()
{
return id;
}
public void setId(long id)
{
this.id = id;
}
public void destroy() {}
}Here's my Test:
package com.grocery2dinner.actions;
import javax.persistence.EntityManager;
import org.jboss.seam.mock.SeamTest;
import org.testng.annotations.Test;
import com.grocery2dinner.model.Category;
@SuppressWarnings("unchecked")
public class CategoryManagerActionTest extends SeamTest
{
@Test(dependsOnMethods={"testSave"})
public void testFind() throws Exception
{
new FacesRequest()
{
@Override
protected void invokeApplication() throws Exception
{
setValue("#{catManager.id}", 1);
invokeMethod("#{catManager.find}");
}
@Override
protected void renderResponse() throws Exception
{
Category cat2 = (Category) getValue("#{category}");
assert cat2.getName().equals("Food");
System.out.println(cat2.getCategory().getId());
assert cat2.getCategory().getId() == 1;
}
}.run();
}
@Test()
public void testSave() throws Exception
{
new FacesRequest()
{
@Override
protected void updateModelValues() throws Exception
{
setValue("#{category.name}", "Food");
Category cat = (Category) getValue("#{category}");
System.out.println("Category Name:" + cat.getName());
assert cat.getName().equals("Food");
}
@Override
protected void invokeApplication() throws Exception
{
invokeMethod("#{catManager.save}");
}
}.run();
new FacesRequest()
{
@Override
protected void invokeApplication() throws Exception
{
EntityManager em = (EntityManager) getValue("#{entityManager}");
Category found = em.find(Category.class, new Long(1));
assert found != null;
assert found.getId() == 1;
assert found.getName().equals("Food");
}
}.run();
}
}
It will run the testSave test just fine, but fails every time for the testFind. Thanks in advance for any help.
