TypeAhead Widget not working with some Validators, like HiddenUnless

[jbtwist]

Describe the bug
When you combine TypeAhead Widget with attributes for validators added at render_field function, it won't work because those validators won't be added

To Reproduce
Steps to reproduce the behavior:

1. Go to any registration form (in my case, I went to RegistrationFormForm)
2. Add a first (A) StringField with HiddenUnless validator and TypeaheadWidget
3. Add a second (B) StringField only with HiddenUnless validator
4. Activate the field that triggers the HiddenUnless, it will only work on B.

Expected behavior
I expect the HiddenUnless validator (and other extra validators) to work in combination with Typeahead widget.

Additional context
I'm not sure if this issue is afecting to more widgets. For example I think it is afecting to the ckeditor_widget, but I have not tested it.

I don't think we are using this combination anywhere in Indico, are we? The client-side validators that add magic like HiddenUnless are somewhat fragile when it comes to non-standard fields (anything that's not a standard form field but makes heavy use of JS), so unless this is breaking anything in the core I think it's unlikely that we are going to fix this (but a PR is welcome as long as it's not likely to break anything)

[jbtwist]

Yes, I am preparing the PR that fix this, I don't think It will break anything because it is mostly copied from the Date-Widget logic, and it would fix an Issue at the UN side.

OK, thanks! Please open the PR against the 3.0.x branch.

I cannot push a new branch to the proyect, can you tell me why can't I and how to add my PR then please?

[ThiefMaster]

We're using the standard workflow pretty much all projects on github uses, so you need to fork the repo and push the branch to your fork...

oh, ok, tyvm
