Error in sidebar when using conditions to show/hide field

[JoeriE]

Bug Description

I've a collection with two linked taxonomies. One taxonomy should only be visible if the other collection has a certain value, example:
Expertise categories has entries: expertise, news and projects
Expertise tags should only be visible if expertise categories has value expertise.

I've added this as a condition in the cp:

But then the sidebar breaks because of an javascript error:
Sidebar before

Sidebar after

Javascript error
SyntaxError: Unexpected token ':' at _default.passesCondition (Validator.js:209) at Validator.js:62 at underscore.js:926 at underscore.js:255 at Function.v.each.v.forEach (underscore.js:186) at Function.v.filter.v.select (underscore.js:254) at Function.v.reject (underscore.js:262) at v.each.v.<computed> [as reject] (underscore.js:1639) at _default.value (Validator.js:62) at _default.value (Validator.js:33)

Environment

Install method (choose one):

Hi there! I've just attempted to re-produce this issue and I don't seem to get the console error or the fields hiding from my sidebar. For reference, here's the two fields I tested with in my blueprint.

      -
        handle: show_hello
        field:
          options:
            'yes': 'Yes'
            'no': 'No'
          multiple: false
          clearable: false
          searchable: true
          taggable: false
          push_tags: false
          cast_booleans: false
          display: 'Show Hello'
          type: select
          icon: select
          listable: hidden
      -
        handle: hello
        field:
          input_type: text
          antlers: false
          display: Hello
          type: text
          icon: text
          listable: hidden
          if:
            show_hello: 'equals yes'

Would you be able to share the two fields from your blueprint that are causing issues so I can see if I can reproduce with the same field names etc?

@damcclean Here's the blueprint of the two fields:

      -
        handle: expertise_categories
        field:
          type: terms
          taxonomies:
            - expertise_categories
          display: 'Expertise categories'
          mode: select
          max_items: 1
      -
        handle: expertise_tags
        field:
          type: terms
          taxonomies:
            - expertise_tags
          display: 'Expertise tags'
          mode: select
          listable: hidden
          if:
            expertise_categories: 'equals expertise'

Thanks!

Thanks for providing the fields! I can confirm, the issue also occurs for me as well. It seems like an issue with the Validator class which deals with the conditions.

If you remove the if part, it obviously starts working again.

Should have spotted this sooner. This issue is a duplicate of #2534.
