In JSR303 § 4.2 ConstraintViolation, there is the following note: “From rootBean and propertyPath, it is possible to rebuild the context of the failure” The chapter continues with several examples of these Node/Path objects. Unfortunately the specification doesn't make any further statements about how JSF or any other toolkits *should* infer what components are in violation, but the spec is framework agnostic afterall… > b) Validation in 2 phases > This is due to the fact that you need all the field values in the > model before you can do any multifield validation. > > Within the Process Validation phase, the JSF validations on a single > field takes place (required, within limits, etc ...).

Yes this makes sense, I just wanted to clarify I wasn't doing something wrong, missing configuration, etc. I think it is acceptible for the user interface that the more complex validations happen in a second pass. -- Gerald Turner Email: [email protected] JID: [email protected] GPG: 0xFA8CD6D5 21D9 B2E8 7FE7 F19E 5F7D 4D0C 3FA0 810F FA8C D6D5
