Problem Solved:
After rooting around in my ApplicationResources.properties file I found
a misspelling in my message name. I would have expected the framework
to catch the error in the lookup similar to what happens in other areas
of struts when a message resource cannot be found. Typically a message
tells you that XXX.title could not be found. Perhaps this test is done
within the validation framework and my bypass caused an unforseen
problem.

I am using the Validation Framework within struts and I need to
perform
some validations that I cannot do using the framework. I have created
an ActionForm
that extends ValidatorForm and in my validate method I first call
super.validate. Once the errors have been returned I then perform my
own
additonal validations
and add to the errors object returned from the super.validate. I then
return the errors object from my validate routine. All appears to
work
ok if I use the standard
struts errors tags to present the errors on the page. However if I
use
the tags that come with the validator i get the following exception
only
when processing errors
that I created:

I am sure it is the way I am creating the additional errors but it
looks very straightforward.
Here are the tags I am putting in my JSP page:
<validator:errorsExist>
<bean:message key="errors.header"/>
<validator:errors id="error">
<li><bean:write name="error"/></li>
</validator:errors>
</validator:errorsExist>
Here is a sample of how I am creating my error
errors.add("password",new
ActionError("enrollmentform.error.password.maskmsg"));
Any tips would be appreciated.
