Question

Please check the following JSFiddle: http://jsfiddle.net/rhulshof/6bd4g/4/

I’m experiencing 2 problems which I just can’t solve:

1. I’m unable to display the number of validation errors in the View. Self.errors() doesn’t seem to be an observable. Edit:: It works for the initial self.articles() rows; but just not for the rows added to the DOM later.
2. When adding two or more rows (articles), it says I have more validation errors than it actually has

Answer 1

I have a partial answer, you need to modify your validation configuration object

ko.validation.configure({
    decorateElement        : true,
    errorElementClass      : 'error',
    insertMessages         : true,  // had been set to false.
    parseInputAttributes   : true
});

That will cause the messages to occur.

I’m not very familiar with the the knockout validation plug in, but once it has an error, the count doesn’t go below 1 for some reason. Not sure why that is happening.

EDIT

The count of error messages being off by 1 is a bug. The first error message in the message list is “null“. It is discussed in issues log at https://github.com/ericmbarnard/Knockout-Validation/issues/99
