Velocity in errorMessage of validator?

[levi]

Hi,

How do we use velocity expressions in the errorMessage?

E.g. something like this (doesn't seem to be working?):

	<validators>  
                <validator type="serverCustom">  
                    <serverCondition><![CDATA[ 
                        $value <= $dataSources.StockItem.fetchById($record.itemId).quantity 
                    ]]></serverCondition>  
                    <errorMessage>We don't have $value in stock, only $dataSources.StockItem.fetchById($record.itemId).quantity</errorMessage>  
                </validator>  
            </validators>

btw, there is no field 'errorMessage' explained here:

The errorMessage is not a Velocity context, just a simple text substitution context. See the DMI validation example for how you can make values available for use in the errorMessage (specifically the call to addErrorMessageVariable()).
