Hi everybody.
I'm trying to edit an entity via a beaneditform which has some other
entities inside. I'll write down a simple case so that it's easy to
understand the issue.
The tml file has the following line:
This object member is an EntityB object:
public class EntityB{
private String sb;
public String getSb() {return sb;}
public void setSb(String sb) {this.sb = sb;}
private EntityA ea;
public EntityA getEa() {return ea;}
public void setEa(EntityA ea) {this.ea = ea;}
}
EntityA is a simple class:
public class EntityA{
private String s1;
public String getS1() {return s1;}
public void setS1(String s1) {this.s1 = s1;}
private int i1;
public int getI1() {return i1;}
public void setI1(int i1) {this.i1 = i1;}
}
Finally, the page class has the following code:
@Property
private EntityB member;
@Inject
private BeanModelSource beanModelSource;
@Inject
private ComponentResources resources;
public BeanModel getModel(){
BeanModel result =
beanModelSource.createEditModel(EntityB.class,
resources.getMessages());
result.add("string1",new EntityBPropertyConduit1());
return result;
}
And the EntityBPropertyConduit1 class is as follows:
public class EntityBPropertyConduit1 implements PropertyConduit {
@Override
public Object get(Object instance) {
EntityB myObject = (EntityB) instance;
if(myObject.getEa()==null){
return new String();
}
return myObject.getEa().getS1();
}
@Override
public void set(Object instance, Object value) {
EntityB myObject = (EntityB) instance;
String myValue = (String) value;
if(myObject.getEa()==null){
myObject.setEa(new EntityA());
}
myObject.getEa().setS1(myValue);
}
@Override
public Class getPropertyType() {
return String.class;
}
@Override
public <T extends Annotation> T getAnnotation(Class<T> arg0) {
// TODO Auto-generated method stub
return null;
}
}
With all of this, I get the error
The data type for property 'string1' of
project.example.entities.EntityB@21ec03 is null.
What am I missing?. I though once you give the beanmodel the
propertyconduit, it knows how to deal with the property...
