We show all errors in a list using ko.group's
errors
method. We have some observableArrays in the view model for which we created computeds filtering them. That caused validation messages to appear twice. The reason was that group's traverse (when using deep) follows eachko.observable
andko.computed
inherits fromobservable
.Therefore I have added an knockout extender 'ignoreInValidationGroup'.
This extender can be used to flag a Knockout Observable to be ignored in validation groups.
When the extender is set the observable will not be added to validation groups.
Rules added to a flagged obserable still apply but the errors are not shown in any group.
