    Graph Validator

    srinivas nandula Newbie

      I am using rich graph validator hoping to validate an object. The graph validator is an interface with one method called validateGraph which takes in an object and validates it.

      The default implementation for this interface is org.richfaces.validator.FacesBeanValidator.

       

      This class implements both the Validator interface and the GraphValidator interrface and the corresponding methods implemented.

       

      when my application is invoked, i observed that the validate method is being invoked rather than the validateGraph method. Why is this the case? when i used rich:graphValidator in my JSF Application, i would logically assume that the method validateGraph should be invoked correct?

       

      Can someone help me understand how i can get the validateGraph method invoked?

       

      Many thanks for this help.

          Why are you using rich:graphValidator to validate a single object? surely the idea is to use it to this to perform

          bean validation in the process validations phase when all components (that are children of the graphValidator tag)

          have passed validation.

           

          For a single object is it not more straightforward to just use a custom validator? It would be easier if you'd post

          some code up really.

            I am using graph validator because i am doing cross field validation as well on the object. With JSF2 if i want to use Hibernate validator and perform cross field validation, i see that graph validator is the only way to go or use SEAM. We are already using webflow for navigation, so i am not sure SEAM can be used in that context.

             

            I am trying to read carefully how graph validator works and it could be this.

             

            Graph validator validates all the fields first using Bean validator. If any of the values are not validated. it throws an error. Once those errors are corrected, it probably does the object validation at that poing and all my @AssertTrue annotated methods will be validated. Am i right to think like that?

             

            Even if  the  implementation is to work as i assume above, i am having issues with the validate value method. I have 2 buttons on the same page which require different validation groups. i am able to assign validation groups correctly to the graph validator based on the button click. But the validation messages i see on my page are not consistent every time i click the button. Sometimes 4 messages show up with validation errors. If i click the same button again, this time, i get only one message. Same groups are being validated, but validations are different. I am not sure why this happens.

             

            Here is my code. Hopefully it can be understood.

            The Section identified in BOLD are the 2 button actions. I am updating the validation groups on button click. This works fine. I can see that the validator is using the right groups.

            When i click the "Details" only the routing number field should be validated. For this i created the RoutingNumberValidation group.

            When i click the "OK" Button all the fields should be validated. For this i created the CaregiverStipendValidation group.

             

            This is how it works.

             

            1. I Click the Details button, only the routing number field gets validated and i get that validation message. (Routing number is invalid)

            2. I do not correct the error, but immediately click the OK button. I get 4 validation messages. on the dates, routing number and bank name. None of the assert true methods are validated at this time

            3. i still do not correct the error, but click the OK button again. This time, i only get one message saying End Date is invalid.

             

            In both cases 2 and 3 i already confirmed that the group being used is the CargiverStipendValidation. Why am i getting 4 validation messages one time and 1 validation message the other time, when i click the same button? This is my problem. For all the above invocations the validate method on the GraphValidator is being invoked. Not the validateGraph method.

             

            I hope i make sense.
