Sorry if this is somewhere else and I missed it, but I have a Custom
Widget that I need to be able to add multiple times to another custom
widget I am creating. I do not seem to understand something about this
process and so I get the following errors:
"Different parents for double associations"
"The other component is added to a parent component more than once."
So basically, the first one gets nuked and only the second one shows
up. What am I missing? Can someone please assist me in understanding
what is wrong. Thank you so much in advance. Below is the code:
public class FirstClass extends Composite
{
public FirstClass()
{
Image image = new Image("img/picture.png");
AbsolutePanel element = new AbsolutePanel();
element.add(image, 0, 0);
initWidget(element);
}
}
public class SecondClass extends Composite
{
public SecondClass()
{
HorizontalPanel element = new HorizontalPanel();
VerticalPanel elementA = new VerticalPanel();
element.add(elementA);
VerticalPanel elementB = new VerticalPanel();
element.add(elementB);
elementA.add(new FirstClass());
elementB.add(new FirstClass());
initWidget(element);
}
}
