Hi, I'm currently trying to modify the error message for converter errors in z3c.form. For instance, if I have an Int() field and input characters there, the message is: The entered value is not a valid integer literal. So, I'd like to write a message such as "Please enter numbers only". I tried now to register a custom error class like this: ------------------------ IntErrorMsg = error.ErrorViewMessage( u'Please enter numbers only.', error=zope.schema.ValidationError, field=IPerson['personnumber']) zope.component.provideAdapter(IntErrorMsg, name='message') ------------------------ The problem with this is, that the error I need to create the error class for, seems to be a zope.schema.ValidationError. This way, all errors are reported with the error class above, which is bad. So, is there a more specific error class for converter errors (I could not find one)? Or is there a better way to solve my problem? Best Regards, Hermann -- hermann@qwer.tk GPG key ID: 299893C7 (on keyservers) FP: 0124 2584 8809 EF2A DBF9 4902 64B4 D16B 2998 93C7
