RE: [FormProc-developer] multi-validator

[Anthony E. <me...@an...>]

FormProc doesn't support multiple validators for an element in the
manner which you have shown below.  To use multiple validators you
should use a FormValidatorGroup.  A FormValidatorGroup can hold any
number of FormValidators.  And since the FormValidatorGroup is a
FormValidator itself you can nest form validators.

The type mapping for the FormValidatorGroup is specified in the
formproc.xml file.  I have used the word "group" in the example below.

Thus the proper configuration would be:

<formproc:element name="age">
  <formproc:validator type="group">
    <formproc:validator type="rule">
      <rule>org.formproc.example.IsIntRule</rule>
      <formproc:error lang="en">Valid age must be
integer.</formproc:error>
    </formproc:validator>
 		
    <formproc:validator type="expression">
      <pattern>^(2[0-9])$</pattern>
      <formproc:error lang="en">Valid age must be between
20-29.</formproc:error>
    </formproc:validator>

  </formproc:validator>   

  <formproc:message lang="en">Valid age required.</formproc:message>
 
</formproc:element>


If you are still having problems then please mention which version of
FormProc you are using in any future messages.

Sincerely,
Anthony Eden
