But if I would like to have just one rule to overwrite error messages generated by two rules and display just one error message? For example: - one rule - built-in 'email' to initially check if email is ok - second rule - callback to check something more complex (for example if email is in DB or something). Is it good way to do it? Can I put both rules into one callback rule calling buil-in rule first? -- Best regards, Sebastian
