I have gone through struts validator framework.
Currently we have to implement only client side validation using struts validator framework in our project.
We have requirement where we have one drop down with values YES and NO. When I select YES , then one text box is displayed and in this case only, contents of textbox becomes mandatory.
If I select NO, then contents of textbox is not mandatory.
I think , requiredif or validwhen can resolve my problem.
I have checked in struts documentation but it does not clearly specify , whether they are server side and which are client side validations [amongst the available in struts validator framework]
