Demonstration API definition

                example: success

Extracted the dist folder from swagger-UI and added the followingswaggerEx.yaml file to it:

In the index.html folder I made the following change:

  // Build a system
  const ui = SwaggerUIBundle({
    url: "swaggerEx.yaml",
    dom_id: '#swagger-ui',
    deepLinking: true,
    presets: [
      SwaggerUIBundle.presets.apis,
      SwaggerUIStandalonePreset
    ],
    plugins: [
      SwaggerUIBundle.plugins.DownloadUrl
    ],
    layout: "StandaloneLayout"
  })

Expected Behavior

As in swagger 2.0, I expected that the required parameters would be validated such as:

Current Behavior

With the new UI I see that the required parameter validation does not occur and the call keeps loading but never gets executed. Here is a screen shot with that behavior:

Context

We are trying to document our API using Swagger. Right now the documentation part works but if we want to provide user with the ability to try out the API we cannot do that because of this issue.

Thank you.

@owenconti can you take a look?

[shockey]

It'd be great to have this fixed before Friday's release.

[owenconti]

Looking into it now.

[zaheena]

Thank you for the fix!

Hi, @owenconti , @webron , @shockey !
Topic starter's example still not working on https://editor.swagger.io. After _Try it out -> Execute_ Id path parameter is not highlighted in red. This is normal?

[shockey]

@bronekrab, the issue is a little different: the required warning isn't showing, but the execute state isn't running away either.

that being said, i see it too - i'll reopen this.

[shockey]

This will be fixed (again) in tomorrow night's release.

Thanks for the heads up on the regression, @bronekrab!
