public void setName(String name) {
this.name = name;
}
}
TT2.java
----------------------------
public class TT2 extends TT1 {
private String v2;
public String getV2() {
return v2;
}
public void setV2(String v2) {
this.v2 = v2;
}
}
CoercTest.java
-----------------------
public class CoercTest {
@Persist
private TT1 testObject;
@OnEvent(component="typeTO1")
public void onTypeTO1() {
setTestObject(new TT1());
}
@OnEvent(component="typeTO2")
public void onTypeTO2() {
setTestObject(new TT2());
}
public TT1 getTestObject() {
return testObject;
}
public void setTestObject(TT1 testObject) {

}
public void onSubmit() {
testObject = null;
}
public boolean isTestObjectNotNull() {
