Serialization of validator functions that accept arguments

[udos86]

Validators that accept an argument like Validators.maxLength cannot be serialized at the moment.

Will probably introduce a breaking change to solve this.

Hi @udos86,
This is great improvement, however, it seems like there is not way to provide custom validators. By "custom validator" I mean a simple functions, which I previously just included in validators array. As far as I understand currently ng2-forms just picks validators function from @angular/forms/Validators, it means that there is no way to use custom validators.

@DavyJohnes

In order to use custom validators please provide them via NG_VALIDATORS / NG_ASYNC_VALIDATORS at first (see http://blog.thoughtram.io/angular/2016/03/14/custom-validators-in-angular-2.html).

But there is a bug, you're right!

[udos86]

@DavyJohnes Please have a look at 8ddf56c. This fix allows you to reference any custom validator given that it's provided via NG_VALIDATORS or NG_ASYNC_VALIDATORS.

@udos86 thanks a lot, will try to use this new approach.

[udos86]

@DavyJohnes You're welcome! Thank you for letting me know about the bug.

@DavyJohnes I've added a little guide in the README.md: https://github.com/udos86/ng2-dynamic-forms#custom-validators
