If I try to use method select just after creation ComboBox throws a NullPointerException. For example the next code:
Code:
ComboBox comboBox = new ComboBox();
            comboBox.setStore(listStore);
            comboBox.setDisplayField("name");
            comboBox.setEditable(true);
            comboBox.select(1);
gives
Code:
[ERROR] Uncaught exception escaped
java.lang.NullPointerException: null
    at com.extjs.gxt.ui.client.widget.form.ComboBox.select(ComboBox.java:351)
PS. I have 3 items in the comboBox and it works well without using method select. But I need to select values.
