allOf required property not composing properly #1390
Description
If you take the following swagger definition:-
{
"swagger": "2.0",
"info": {
"title": "An API Definition",
"version": "0.1"
},
"paths": {
"/users": {
"post": {
"operationId": "getUser",
"produces": [
"application/json"
],
"parameters": [{
"name": "newUser",
"in": "body",
"required": true,
"schema": {
"$ref": "#/definitions/newUser"
}
}],
"responses": {
"201": {
"description": "Details of the user"
}
}
}
}
},
"definitions": {
"user": {
"type": "object",
"required": ["username", "firstName", "lastName"],
"properties": {
"username": {
"type": "string"
},
"firstName": {
"type": "string"
},
"lastName": {
"type": "string"
}
}
},
"newUser": {
"allOf": [{
"$ref": "#/definitions/user"
},
{
"type": "object",
"required": ["email", "roles"],
"properties": {
"email": {
"type": "string"
},
"roles": {
"type": "array",
"items": {
"type": "string"
}
}
}
}
]
}
}
}
Then newUser is a composite of user and the additional properties defined on newUser. In the Swagger Editor the UI shows this correctly.
However, it should also compose the required property which it is failing to do. user states that username, firstName, and lastName are required, and newUser states that email, and roles are required. However, it is only marking those on newUser as required.
This should be a super-set of these.
