Problems with Apache Commons Validator

Question

Hello there,
I got a quiet big problem using the a.m. validation framework. When defining a validation rule for a property like this:
<formset>
<form name="testForm">
<field property="firstName" depends="isEmail">
<arg0 key="testForm.firstname"/>
</field>
</form>
</formset>
and instanciating my validator as follows:
Validator validator = new Validator(resources, "testForm");
validator.setParameter(Validator.BEAN_PARAM, name);
everything works fine! I get a correct ValidatorResult object with a correct validation value.
But as soons as I define a second Validation on the same property like this:
<formset>
<form name="testForm">
<field property="firstName" depends="isEmail,isBlankOrNull">
<arg0 key="testForm.firstname"/>
</field>
</form>
</formset>
Nothing works anymore. When iterating over the ValidatorResults object I only get one ValidatorResult object for "isEmail" with a wrong validation value. There should be two working ValidatorResult objects for "isEmail" and "isBlankOrNull"?!?!
Are two validation method in the depends-Attribute not allowed (although it is defined in the standard)?
You can assume, that the used validator class is conform to the given org.apache.commons.TestValidator!
For any help, thx in advance!

Hey Aaron,
Could you post your code for your <field>...</field>?
Here is an example from: http://www.jsn-server3.com/struts-documentation/userGuide/dev_validator.html
<field
    property="firstName" indexedListProperty="dependents"
    depends="requiredif">
  <arg0 key="dependentlistForm.firstName.label"/>
  <var>
    <var-name>field[0]</var-name>
    <var-value>lastName</var-value>
  </var>
  <var>
    <var-name>field-indexed[0]</var-name>
    <var-value>true</var-value>
  </var>
  <var>
    <var-name>field-test[0]</var-name>
    <var-value>NOTNULL</var-value>
  </var>
</field>
<field
    property="dob"
    indexedListProperty="dependents"
    depends="requiredif,date">
  <arg0 key="dependentlistForm.dob.label"/>
  <var>
    <var-name>field[0]</var-name>
    <var-value>lastName</var-value>
  </var>
  <var>
    <var-name>field-indexed[0]</var-name>
    <var-value>true</var-value>
  </var>
  <var>
    <var-name>field-test[0]</var-name>
    <var-value>NOTNULL</var-value>
  </var>
</field>
<field
    property="coverageType"
    indexedListProperty="dependents"
    depends="requiredif">
  <arg0 key="dependentlistForm.coverageType.label"/>
  <var>
    <var-name>field[0]</var-name>
    <var-value>lastName</var-value>
  </var>
  <var>
    <var-name>field-indexed[0]</var-name>
    <var-value>true</var-value>
  </var>
  <var>
    <var-name>field-test[0]</var-name>
    <var-value>NOTNULL</var-value>
  </var>
  <var>
    <var-name>field[1]</var-name>
    <var-value>insureDependents</var-value>
  </var>
  <var>
    <var-name>field-test[1]</var-name>
    <var-value>EQUAL</var-value>
  </var>
  <var>
    <var-name>field-value[1]</var-name>
    <var-value>true</var-value>
  </var>
  <var>
    <var-name>field-join</var-name>
    <var-value>AND</var-value>
  </var>
</field>
</form>" Which is read as follows: The firstName field is only required if the lastName field is non-null. Since field-indexed is true, it means that lastName must be a property of the same indexed field as firstName. Same thing for dob, except that we validate for date if not blank.
The coverageType is only required if the lastName for the same indexed bean is not null, and also if the non-indexed field insureDependents is true.
You can have an arbitrary number of fields by using the [n] syntax, the only restriction is that they must all be AND or OR, you can't mix. "
Hope that helps,
Nate
