Hi joshi, thanks for your response. I have a class which extends GenericForwardComposer<component>. In this class I had written a common method to fill the combobox without using renderer(just appeneding items). I am using this class as parent class for all my controller classes. I will invoke this method from respective controller to fill the comboboxes. Now I want to apply the atuodrop option. For doing this I had modified my code as below

public void fillComboBox(Combobox combobox, List<ValueLabel> list) {
    combobox.setModel(new SimpleListModel(list) {
        protected boolean inSubModel(Object key, Object value) {
            String idx = key.toString();
            ValueLabel myItem = (ValueLabel)value;
            return idx.length() > 0 && myItem.getLabel().startsWith(idx);
        }
    });

    combobox.setItemRenderer(new ComboitemRenderer () {
        public void render(Comboitem item, Object data, int count) throws Exception {
            ValueLabel valueLabel = (ValueLabel)data;
            item.setLabel(valueLabel.getLabel());
            item.setValue(valueLabel.getValue());
        }
    });

}

But the above code is not working.

Hi Joshi, I am not getting any issue, the execution was entering into inSubModel method but not going into the render method. Why it was skipping at that line I didnot understand. Is there any thing wrong in my above code.
