I have something like that in my code. I use a
com.google.gwt.user.client.ui.LayoutPanel
<g:center>
<g:LayoutPanel ui:field="placeholder" />
</g:center>
and in java code :
@UiField
LayoutPanel placeholder;
public void setPlaceHolder(IsWidget w)
{
placeholder.clear();
if (w != null) {
placeholder.add(w);
}
}
Hope it will help,
Alexandre.
