Bug 189999 [PropertiesView] [PropertiesView] Setting 1 value causes very slow recursive refresh
I have a properties with a hierarchy. Everything is read-only except for the leaf nodes. Setting a value takes about 5 seconds on my Core2Duo and seems to have possibly gotten even slower in RC2. This stems from the call to PropertySheetEntry.refreshFromRoot in the setValue method. Why should 1 value cause a total refresh? If other values were dependent, shouldn't they have listeners? This is a big problem for me as it will be very hard for my users to be productive with such a slow interface. I realize its late to get something in for 3.3. If there is a workaround, I would really like to know about it so I don't have to reimplement the property view.

    private void addColumns() {
        
        TreeColumn[] columns = tree.getColumns();
        for (int i = 0; i < columnLabels.length; i++) {
            String string = columnLabels[i];
            if (string != null) {
                TreeColumn column;
                if (i < columns.length) {
					column = columns[i];
				} else {
					column = new TreeColumn(tree, 0);
				}
                column.setText(string);
            }
        }
        tree.addControlListener(new ControlAdapter() {
            public void controlResized(ControlEvent e) {
                Rectangle area = tree.getClientArea();
                TreeColumn[] columns = tree.getColumns();
                if (area.width > 0) {
                    columns[0].setWidth(area.width * 40 / 100);
                    columns[1].setWidth(area.width - columns[0].getWidth() - 4);
                    tree.removeControlListener(this);
                }
