When using the select form we cannot pass the items as a Collection of Map, the items must be a java bean.

For example in this case the countries variable is a List of Map objects

<form:select path="countryCode" items="${countries}" itemLabel="description" itemValue="country_code"></form:select>

The itemLabel "description" and itemValue "country_code" should be the keys of the Map, but the page gives the following error

org.springframework.beans.NotReadablePropertyException: Invalid property 'country_code' of bean class [org.apache.commons.collections.map.ListOrderedMap]: Bean property 'country_code' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

.....

Should the method doRenderFromCollection in the class OptionWriter check to see if the item is a instance of Map and extract the values of the Map instead?

If you agree with this change I can provide a patch.

Thanks
