Error using JSON editor with array of $ref objects

[scottohara]

One of my end users has reported a problem when using type: "array" in the schema of a request body parameter.

On closer inspection, the error only appears when the jsonEditor is set to true.

The error is:
Uncaught TypeError: Cannot read property 'required' of undefined, and occurs in the following line in lib/jsoneditor.min.js:

s.required && Array.isArray(s.required) && e.schema.required && Array.isArray(e.schema.required) && (n.required = e.schema.required.concat(s.required)));

(s is the undefined reference. s is assigned a few lines above as s = this.types[t]; and the problem seems to be that this.types is an empty array - [])

Below is a reduced YAML example that should demonstrate the issue.

1. Set jsonEditor to false and the API renders correctly
2. Set jsonEditor to true and the above error occurs

The same problem. It's real cool feature. Guys, are you going to fix it? Thanks

One of my teammates reported this last week and wanted to show another hand that we are affected also.

it works if maximize jsoneditor.min.js and simplify ternary operator in 2583 line to view:

n = i({}, e.schema), n.type = s
// was:
// "string" == typeof s ? (n = i({}, e.schema), n.type = s) : 
// (n = i({}, e.schema, s), n = e.jsoneditor.expandRefs(n), s.required && Array.isArray(s.required) && e.schema.required && Array.isArray(e.schema.required) && (n.required = e.schema.required.concat(s.required)));

But I don't know what the meaning of these lines. Anyway thanks for Swagger UI.
JSON editor in swagger ui is not like as editor on official page http://editor.swagger.io/ (there is 'Try this operation')
Does anybody know how to integrate json editor from oficial page to project?

It seems that this issue can be resolved by updating to the latest version (v0.7.28) of the JSON editor. (Version currently used in this project is v0.7.22)/

Pull request coming shortly....
