I've got a problem (I think I found a bug) with GWT 1.4.60 when
copying data-classes that were received from a servlet. I have a proof-
of-concept and can send it to anybody being interested (I don't want
to attach it to this message to save bandwith).
Here the Entry-point in short form:
public void onModuleLoad() {
// create GUI-elements and add them to the root-panel, some of
them
// are declared as global variables to allow to access them later
ServerFunctionality.Util.getInstance().getTestData(new
AsyncCallback() {
public void onSuccess(Object result) {
data = (TestDataClass) result;
refreshValues();
}
public void onFailure(Throwable caught) {
Window.alert(caught.getMessage());
}
});
}
private void refreshValues(){
label.setText(data.name);
label_1.setText(Integer.toString(data.value));
label_2.setText(Boolean.toString(data.truth));
TestDataClass copy = new TestDataClass(data);
label2.setText(copy.name);
label_3.setText(Integer.toString(copy.value));
label_4.setText(Boolean.toString(copy.truth));
}
Here is the source of TestDataClass:
public class TestDataClass implements Serializable {
public TestDataClass(){
// nothing to do
}
public TestDataClass(TestDataClass source){
this.name = source.name;
this.value = source.value;
this.truth = source.truth;
}
private static final long serialVersionUID = 1L;
public String name;
public int value;
public boolean truth;
}
The servlet ServerFunctionalityImpl is simply instantiating
TestDataClass
and fill in some values
When running the whole thing in Hosted Mode, everything works fine,
when pressing the Compile/Browse-Button I see the following values
in the Browser:
Text name
Number 5
Boolean true
Copy of Text
Copy of Number 0
Copy of Boolean false
WTF?
Best regards, Lothar
