RE: custom validator question

[claire knowles]

I had a custom validator 'futureDate' for which I needed to pass in a
date and time which were 2 different form fields, to check that the date
was in the future.

I passed 2 different values into a custom parameter using two args and
vars:

<form name="form">
<field property="emailDate" depends="required, mask, futureDate">
        <msg name="mask" key="errors.invalid"/>
      <arg0 key="form.emailDate"/>
      <arg1 key="form.emailTime"/>
      <var>
        <var-name>mask</var-name>
        <var-value>${dateMask}</var-value>
      </var>
      <var>
            <var-name>time</var-name>
            <var-value>emailTime</var-value>
      </var>
</field>
</form>

In the custom validator I retrieved the two values using:

public static boolean validateDate(Object bean, ValidatorAction va,
Field field, ActionErrors errors, HttpServletRequest request)
    {
        String value;

        if (isString(bean))
        {
            value = (String) bean;
        }
        else
        {
            value = ValidatorUtil.getValueAsString(bean,
field.getProperty());
        }

        String propertyTime = field.getVarValue("time");
        String valueTime = ValidatorUtil.getValueAsString(bean,
propertyTime);

        . . . . .

Hope this helps

Subject: custom validator question


I'm creating a custom validator to enforce a <= relationship between 2
date fields and am having a problem.

A validator method gets a Field arg for the field with which it's
associated in validation.xml, but I need to also get the Field object
for the other date field. I need this so that I can get its property
name for display in an error message. (I'd also like to be able to get
the field's datePattern.) I can't figure out how to do this.

Any help would be much appreciated!

Here's the relevant part of my validation.xml file:

      <form name="ActivityViewForm">
        <field
           property="starting"
           depends="date">
          <arg0 key="ActivityViewForm.starting.displayname"/>
          <var>
            <var-name>datePatternStrict</var-name>
            <var-value>MM/dd/yyyy</var-value>
          </var>
        </field>
        <field
           property="ending"
           depends="date,date1LEdate2">
          <arg0 key="ActivityViewForm.ending.displayname"/>
          <var>
            <var-name>datePatternStrict</var-name>
            <var-value>MM/dd/yyyy</var-value>
          </var>
          <var>
            <var-name>date1</var-name>
            <var-value>starting</var-value>
          </var>
        </field>
      </form>
