ko validation with ko 3.4.0 and ko.options.deferUpdates = true;

[jorgevinagre]

Hi there

The sample at http://jsfiddle.net/KHFn8/5424/ doesn´t work as expected when ko deferred updates are set globally.

I´ve tried this:

1. Fill one of the mandatory fields
2. Click submit
3. Click reset
4. All error messages disappear and the validation message for the filed at number 1 appears

Is this a bug on ko validation?

Thanks

Actually this is because of knockout deferring updates until it needs to render. In this case, it seems that showAllMessages run before the updates on the observables are done. Not sure who's fault it is and what's the expected behaviour though...

I've updated you example with a non working version and a working version.

As a quick fix, you can make your example work by running ko.tasks.runEarly(); just before resetting the validation (i.e. showAllMessages(false);).
