DefaultMessageSourceResolver

Hello,

I think this usage should be possible, so please let me know if this
isn't supported.

I am writing some custom validation in onBindAndValidate, and am
rejecting a field in a map.  The specific code is:

errors.rejectValue("accepted['"+agencyName+"']",
~  "errors.required", new Object[] {
~    new DefaultMessageSourceResolvable(
~      new String[]{"signatureCommand.accept.dept."+agencyName})
~  }, null);

My bean looks like:

public class Command {
~  public Map getAccepted();
}

However, when I attempt to reject the field accepted['tax'], I receive a
NPE:

java.lang.NullPointerException
~        at
org.springframework.validation.DefaultMessageCodesResolver.resolveMes
sageCodes(DefaultMessageCodesResolver.java:103)
~        at
org.springframework.validation.BindException.resolveMessageCodes(Bind
Exception.java:163)

org.springframework.validation.BindException.rejectValue(BindExceptio
n.java:152)
~        at
com.hic.eboss.web.SignatureController.onBindAndValidate(SignatureCont
roller.java:143)

This is because the Class of accepted['tax'] was not found (because its
value is null).  There was a similar problem w/ null values in a Map
with the registering of custom property editors.

I believe that DefaultMessageCodesResolver should just handle the case
where the Class is null.

Hope that helps,
Thanks!
Seth
