Spring usage of typeMismatch messages - data-binding

Question

I have done some searches on the web and in stackoverflow to see how to handle the following message that I get on one of my screens:
Failed to convert property value of
type [java.lang.String] to required
type [java.lang.Long] for property
'qtyToShip'; nested exception is
java.lang.IllegalArgumentException:
Could not parse number: Unparseable
number: "a"
From research and from looking at the web I assumed that adding the following to my errors.properties file would produce the desired results:
typeMismatch.shippingCommand.qtyToShip=1. Invalid value for Qty To Ship, accepts only numbers.
typeMismatch.qtyToShip=2. Invalid value for Qty To Ship, accepts only numbers.
shippingCommand.qtyToShip=3. Invalid value for Qty To Ship, accepts only numbers.
qtyToShip=4. Invalid value for Qty To Ship, accepts only numbers.
typeMismatch.java.lang.NumberFormatException=5. Invalid value for {0}, accepts only numbers.
typeMismatch.java.lang.Integer=Must specify an integer value.
typeMismatch.java.lang.Long=Must specify an integer value.
typeMismatch.java.lang.Float=Must specify a decimal value.
typeMismatch.java.lang.Double=Must specify a decimal value.
typeMismatch.int=Invalid number entered
typeMismatch=Invalid type entered
I add integer values to the message to determine which one would show up.
Now at the top of my JSP I have the following:
<center>
<spring:hasBindErrors name="shippingCommand">
<c:if test="${errors.errorCount > 0 }">
<h4>Following errors need to be corrected:</h4>
<font color="red">
<c:forEach items="${errors.allErrors}" var="error">
<spring:message code="${error.code}" arguments="${err.arguments}" text="${error.defaultMessage}"/><br />
</c:forEach>
</font>
</c:if>
</spring:hasBindErrors>
</center>
The above is outside my Form, inside my Form I have the following (testing out ideals)
So the results is that when I run my code to trigger the error, I see that inside my form I get the following message:
1. Invalid value for Qty To Ship, accepts only numbers.
Which comes from this: typeMismatch.shippingCommand.qtyToShip
The outside of the form displayes:
Invalid type entered
What I do not understand is why am I able to display the correct message inside my form but not outside?
In the controller I have added the following:
#Override
protected void initBinder(HttpServletRequest pRequest, ServletRequestDataBinder pBinder) throws Exception
{
NumberFormat numberFormat = NumberFormat.getInstance();
pBinder.registerCustomEditor(Long.class, "qtyToShip", new CustomNumberEditor(Long.class, numberFormat, false));
}
Thanks

Perhaps error.code doesn't guarantee to return the most specific message code. Try to pass error message as a whole:
<spring:message message = "${error}" />
