Re: Struts2 Collection validation
If you want to validate generated fields, i mean a Collection you can do something like this. * Action class private List collection; public void setCollection(String collection) { this.collection = collection; } public String getCollection() { return collection; } List list = this.getCollection() ; for (int i = 0; i < list.size(); i++) { if(list.get(i).equals("")) addFieldError("collection[" + i + " ] ",getText("validation.required")); } by fgsantoyo Julio Alberto Jalón wrote: > > > I'm learning struts2 through the struts2-showcase application example. > From the "Person Manager" functionality I've learned how to send multiples > values from client to server using collections to manage these values, but > now I'd like to know how to validate these values using struts2 > validation.

RE: Struts2 Collection validation
thanks for the links gabriele If I had to make a suggestion to the xwork committers I would suggest their attribute configurations be a bit more specific so instead of Login-validation.xml configured as ... myContext true where by magic incantation and algorithmic manipulation a user object would reference field validations from User-myContext-validation.xml but is'nt this a bit more user-friendly.. true User-myContext-validation.xml this way a build / release manager can 'scan' the configuration file and understand this validator must be in the distro vs waiting for the app to be deployed to production and unsuspecting op gets NPE and then an email is posted to struts users ?

Re: Struts2 Collection validation
You may want to look at type conversion [1] and VisitorValidator [2] to validate those form fields. Also, please note that collection indexing is done with [square] brackets, like in: "persons[2].name" [1] http://struts.apache.org/2.1.2/docs/type-conversion.html#TypeConversion-AnadvancedexampleforindexedListsandMaps [2] http://struts.apache.org/2.1.2/docs/visitor-validator.html 2008/10/16 Julio Alberto Jalón <[EMAIL PROTECTED]>: > > May I didn't explain myself correctly.

Re: Struts2 Collection validation
May I didn't explain myself correctly. What I would like to know is how to validate multiple fields. I'll write an example. I have a form in a JSP which generate the field dynamically. E.g: ID First Name Last Name Where person is a List in the action class. Now, what I would like to know is how could I achieve this fields to be validated. For example, I would like that if the name is filled the last name should be also filled and both can only contains letters and blanks. Well, I don't want you to give me the complete solution ( the expresion or reg expresion), just want to know how I can refer all these fields from the MyActionClass-validation.xml. Hope I've explained better than in the first post. Please, help me. Thanks in advance. - Mensaje original De: Julio Alberto Jalón <[EMAIL PROTECTED]> Para: user@struts.apache.org Enviado: miércoles, 15 de octubre, 2008 12:32:05 Asunto: Struts2 Collection validation I'm learning struts2 through the struts2-showcase application example. From the "Person Manager" functionality I've learned how to send multiples values from client to server using collections to manage these values, but now I'd like to know how to validate these values using struts2 validation. I don't know what to put in *-validation.xml in order to validate these values. Should I use custom validation? Thanks in advance.
