RE: Difference between ValidatorForm and ValidatorActionForm
Hi, ValidatorActionForm - This class extends ValidatorForm and provides basic field validation based on an XML file. The key passed into the validator is the action element's 'path' attribute from the struts-config.xml which should match the form element's name attribute in the validation.xml.

Difference between ValidatorForm and ValidatorActionForm?
I kind of understand it. ValidatorForm validates the form and ValidatorActionForm validates the form based on action path. But why would you prefer one over the other? I mean you can achieve almost the same effect with either. Thanks! - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Difference between ValidatorForm and ValidatorActionForm?
Yansheng, Since ActionForms are intended to be reused across multiple actions, you might have different validation requirements depending on the context that the ActionForm is being used. One Action might require a certain field but that field may not be required for another Action that is using the same ActionForm. Hope this helps. -Original Message- From: Yansheng Lin [mailto:[EMAIL PROTECTED] Sent: Thursday, June 26, 2003 11:52 AM To: 'Struts Users Mailing List' Subject: Difference between ValidatorForm and ValidatorActionForm?

RE: Difference between ValidatorForm and ValidatorActionForm?
So do you have to do anything differently in your validation.xml? Also, where can I find some documentation on this? - Keith -Original Message- From: Butash, Bob [mailto:[EMAIL PROTECTED] Sent: Thursday, June 26, 2003 12:59 PM To: 'Struts Users Mailing List' Subject: RE: Difference between ValidatorForm and ValidatorActionForm?

RE: Difference between ValidatorForm and ValidatorActionForm?
Keith, I'm currently reading Programming Jakarta Struts by Chuck Cavaness. It has been a really good book so far and gives you a strong foundation to build on. In you validation.xml file for the form element's name attribute you need to give the action's name that you want the validation rule to be in effect for. Example validation.xml entry: formset form name=/rootSelection field property=rootPath depends=required arg0 key=formFields.rootPath/ /field /form /formset Example Action Mapping: action path=/rootSelection type=com.eds.bluesphere.propertywizard.component.RootPathSelectionProcess name=rootSelectionForm scope=request validate=true input=/jsp/rootPathSelectionDisplay.jsp /action The ValidatorActionForm will obtain the ActionForm name from your ActionMapping. Hope this helps. -Original Message- From: Kamholz, Keith (corp-staff) USX [mailto:[EMAIL PROTECTED] Sent: Thursday, June 26, 2003 1:05 PM To: 'Struts Users Mailing List' Subject: RE: Difference between ValidatorForm and ValidatorActionForm?

Re: Difference between ValidatorForm and ValidatorActionForm?
The core difference is what will be used as reference when running the validation lets say you have an form object that spans 3 actions ( is shared by ) and all of them have validate = true in the struts-config.xml if you use ValidatorForm to then all of the validation rules you specify will be run. which may or may not be good.. if you use ValidatorActionForm then you can break up the validation rules into chuncks based on the action that was run. The only difference in the validation setup is wether your form entrie referes to the form object or the action. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
