Subject Re: How can I handle validation exception?
Date Wed, 11 Mar 2009 07:36:36 GMT
Thank you Andrus,

Yes, I do not throw the exception myself. But, how am I going to handle
the exception thrown by Cayenne? Or how can I retrieve the error message
from the validationResult when a ValidationException is thrown, so that
I can print it in the GUI?

Is the following correct?

    @Override
    protected void validateForSave(ValidationResult validationResult) {
      super.validateForSave(validationResult);

      if(getCompanyName().equalsIgnoreCase("")) {

          validationResult.addFailure(new ValidationFailure() {

                @Override
                public Object getSource() {
                    return this;
                }

                @Override
                public Object getError() {
                    return Company.CNAME_PROPERTY;
                }

                @Override
                public String getDescription() {
                    return "My error message";
                }
            });
      }
    }
