When i generate a groupbox with caption in zul, the Icon and the label are on the left side in caption.

<groupbox mold="3d" open="false">
<caption
label="ABCDEFG"
image="img/icon_check.png" />
</groupbox>

but when i generate a groupbox with caption direct in java, then the Label is on the left side and the icon on the right side

Groupbox group = new Groupbox();
Caption cap = new Caption("ABCDEFG");
cap.setParent(group);
Image img = new Image();
img.setSrc("img/icon_check.png");
img.setParent(cap);

group.setMold("3d");
group.setOpen(false);
group.setParent(tpmeeting);
