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>

Re: custom validator question
Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
Specify the second field as <var>
<field property="myFirstDate" depends="date,dateCompare">
<var>
<var-name>datePattern</var-name>
<var-value>dd/MM/yyyy</var-value>
</var>
<var>
<var-name>compareDate</var-name>
<var-value>mySecondDate</var-value>
</var>
</field>
Then in your custom validation method:
String datePattern = field.getVarValue("datePattern");
String compareDateProperty = field.getVarValue("compareDate");
String compareDate = ValidatorUtils.getValueAsString(bean,
compareDateProperty);

RE: custom validator question
Posted by claire knowles <cl...@digitalbridges.com>.
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
Claire
