There are workarounds, please open a feature request for this.
you might try overriding:
protected void setFigure(IFigure newFigure) {
if (figure != null) {
unregisterVisuals();
IFigure parent = figure.getParent();
int index = parent.indexOf(figure);
Object constraint = parent.getLayoutManager().getConstraint(figure);
figure = newFigure;
parent.add(figure, constraint, index);
registerVisuals();
} else
super.setFigure(newFigure);
}

Randy,
What do you think about adding something like this to the API for Figure
and EditPart? Certaily could be handled by subclasses, but perhaps handy
enough to consider making more readily available. What do you think?
public int getChildCount(Class c) {
int i = 0;
Iterator iter = children.iterator();
while (iter.hasNext()) {
if (c.isAssignableFrom(iter.next().getClass())) {
i++;
}
}
return i;
}
