Another "not really a bug, but should be fixed, though" issue.

I set my node images like that:
Code:
tree.getStyle().setNodeCloseIcon(myResources.joint_minus());
tree.getStyle().setNodeOpenIcon(myResources.joint_plus());
Yes, those icons (+ and -) are added but they don't replace the default ones (gxt triangles are still there):
