Ted, Regarding field validations, can you provide any reason why the validwhen validator is not provided in Struts 2? . I think this is a step backwards from Struts 1 where we could easily manage conditional validation (validate fieldb only if fielda & fieldc meet some condition)
Also, the validators in Struts 1 returned true/false for success/failure, and we had the option of adding messages or not ; but in Struts 2 the only way to tell a validation failed is by the presence of errors on the field. Both of these limitations (if you will) make conditional validation (without error message for the condition itself) almost impossible. Hope i'm not missing anything here. Please let us know your thoughts Thanks, Joseph On 8/30/07, Ted Husted <[EMAIL PROTECTED] > wrote: > > Struts 2 uses a hierarchical approach to validation which could be > used to support a multi-page workflow.
