You are absolutely right.
This is the code (or what is left of it, and still is not working..)
The following class is called from the class XXX.
The class returns a verticalPanel with all kinds of widgets on it,to
keep my functions grouped together.
The calling code is:
public VerticalPanel expensesPanel(Vector vectorMonthPosts ) {
VerticalPanel expensesBody= new VerticalPanel();
InputPanelWidget panelInput = new InputPanelWidget();
VerticalPanel newDataPanel = panelInput.InputPanelWidget();
expensesBody.add(newDataPanel);
return expensesBody;
}
I omitted other calls to other classes for brevity
The InputPanelWidget class looks like this..

import com.google.gwt.user.client.ui.*;

of the page..
}

}

String didItWork="success";
if (didItWork.equals(result)) {
Window.alert("Succesfully inserted!");
} else {
Window.alert("uh-Oh!?!");
}
}
}
}
I deleted practically all the code, but the problem still persist.
However when I'm not calling this class, the error is gone..So it must
be something in the code. The java code is compiling fine..
Thx for any help..
