Hey John, Thanks for your advice, the example you gave me should handle what I need to do.

Since your property is a setting is a String, you want to make your choices a list of the possible Strings to which to set it. Try something like this... final Map<String, String> choiceMap = new HashMap<String, String>(); choiceMap.put("1001", "Choice 1"); choiceMap.put("2004", "Choice 4"); choiceMap.put("305", "Choice 5"); List<String> choices = new ArrayList<String>(); choices.add("1001"); choices.add("2004"); choices.add("305"); DropDownChoice ddc = new DropDownChoice( "ddc", new PropertyModel(theItem, "type"), choices, new IChoiceRenderer() { public Object getDisplayValue(Object object) { return choiceMap.get(object.toString()); } public String getIdValue(Object object, int index) { return object.toString(); } }); jk --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
