+ * Binds a Tiger enum in a combobox and supports i18n.
+ * The i18n key of an enum is the full classname + "." + enumfield.
+ * For example:
+ * x.y.Season.WINTER = Winter
+ *
+ * configuration happens like this:
+ *
+ * <bean id="binderSelectionStrategy"
+ *
class="org.springframework.richclient.form.binding.swing.SwingBinderSelectionStrategy">
+ * <property name="bindersForPropertyTypes">
