Hi,
I have an Editing page that I would like to use to edit different
object implementing the same class. If I switch the object I want to
edit I get a ClassCastException in the
CoercingPropertyConduitWrapper (see below).
I have created a simple scenario to reproduce this.
First there is a Base Page CoercTest that hast 2 ActionLinks that
lead to the ObjectEditPage
-----------------------------
public class CoercTest {
@InjectPage
private ObjectEditPage editPage;
@OnEvent(component="typeTO1")
public ObjectEditPage onTypeTO1() {
editPage.setTestObject(new TO1());
return editPage;
}
@OnEvent(component="typeTO2")
public ObjectEditPage onTypeTO2() {
editPage.setTestObject(new TO2());
return editPage;
}
}
----------------------------------
TO1 and TO2 both implement TestInterface
This is what ObjectEditPage looks like
-------------------
@Persist
private TestInterface testObject;
public TestInterface getTestObject() {
return testObject;
}
public void setTestObject(TestInterface to) {
this.testObject = to;
}
public Object onSuccess() {
testObject = null;
return CoercTest.class;
}
------------------------
the tml contains just a BeanForm to edit the "testObject"
Now if the user hits the first ActionLink on the CoercTest page,
and submits the form everything looks OK. But as soons as he then
hits the 2. ActionLink to edit an Object of the other SubType of
TestInterface he gets the following Exception
------------------------
java.lang.ClassCastException

----------------------------
Is there anything one can do to have EditingPages that can handle
more than one object type?
