Trimming White Space
Joel Trunick
Is there some clever way to trim white space from text fields, beginning
and end without coding each one?

To achieve this I used a ValidField component with a subclass of
StringValidator (see below). Overkill if all
you want to do is trim whitespace, but I need to enforce string lengths.
package com.logitel.vxt.valid;
/* Extends StringValidator to trim() input field. */
import org.apache.tapestry.valid.StringValidator;
import org.apache.tapestry.valid.ValidatorException;
import org.apache.tapestry.form.IFormComponent;
public class TrimmedStringValidator extends StringValidator
{
public Object toObject(IFormComponent field, String input) throws
ValidatorException
{
return super.toObject(field, (input==null?null:input.trim()));
}
}

You could use a custom IValidator attached to ValidField's to do this,
I believe.
