Very simple: add(new
DropDownChoice("requestStatus",Arrays.asList(ProcessingStatusType.values()),
... ));
the constructor javadoc:
http://static.ddpoker.com/javadoc/wicket/1.4-m2/org/apache/wicket/markup/html/form/DropDownChoice.html#DropDownChoice%28java.lang.String,%20java.util.List,%20org.apache.wicket.markup.html.form.IChoiceRenderer%29
the super class contructor:
http://static.ddpoker.com/javadoc/wicket/1.4-m2/org/apache/wicket/markup/html/form/AbstractChoice.html#AbstractChoice%28java.lang.String,%20java.util.List,%20org.apache.wicket.markup.html.form.IChoiceRenderer%29
The second parameter (Arrays.asList(ProcessingStatusType.values())) are
"The collection of choices in the dropdown". Your model will receive to
setter an item from this list of choices.
