ComboBoxItem - not showing list

Hi all,
I make simple grid, but is not working.

code:

public class TableInfo extends DynamicForm {
    private static final MysqlEditorInfoConstants CONSTANTS = GWT.create(MysqlEditorInfoConstants.class);
    private SelectItem collationBox;
    public TableInfo() {
        private ComboBoxItem collationBox;
        collationBox = new ComboBoxItem("collationBox", CONSTANTS.tableCollation_text());
        collationBox.setValueMap("Cat", "Dog", "Giraffe", "Goat", "Marmoset", "Mouse");
        collationBox.setHint(CONSTANTS.tableCollationHelp_text());
		String[] values = CONSTANTS.mysqlEngineTypes_array();
		LinkedHashMap<String, String> valueMap = new LinkedHashMap<String, String>();

		for (int i=0;i<values.length;i++) {
			valueMap.put(i+"", values[i]);
		}
		collationBox.setValueMap(valueMap);
	collationBox.setShowHint(true);
	collationBox.setWidth(200);
	setFields(new FormItem[] { nameItem, collationBox, engineBox, commentArea});
    }
}
public interface MysqlEditorInfoConstants extends Constants {
	String[] mysqlEngineTypes_array();
}

MysqlEditorInfoConstants.properties :
mysqlEngineTypes_array=MEMORY\\,MyISAM\\,BLACKHOLE\\,MRG_MYISAM\\,CSV\\,ARCHIVE\\,InnoDB

when I run it, all fields is in one line. look here http://2.2ajtaci.appspot.com/
can you tell me what I do wrong ?

Im try it with

collationBox.setValueMap(CONSTANTS.mysqlEngineTypes_array());

but result is same,

thanks

Im do it.

mysqlEngineTypes_array=MEMORY\,MyISAM\,BLACKHOLE\,MRG_MYISAM\,CSV\,ARCHIVE\,InnoDB
engineBox.setValueMap((String[])CONSTANTS.mysqlEngineTypes_array());

but when I run it in local server in eclipse, then collationBox is not showing.
