Problem with "oneOf"

Here is a scheme I am trying to use…

{
  "title": "Configuration",
  "type": "object",
  "properties": {
    "triggers": {
      "type": "array",
      "format": "tabs",
      "title": "Triggers",
      "items": {
        "title": "Trigger",
        "oneOf": [
          {
            "title": "Twitter",
            "type": "object",
            "properties": {
              "track": {
                "type": "string"
              }
            }
          },
          {
            "title": "Instagram",
            "type": "object",
            "properties": {
              "tags": {
                "title": "Tags",
                "type": "array",
                "format": "table",
                "items": {
                  "title": "tag",
                  "type": "string"
                }
              }
            }
          }
        ]
      }
    }
  }
}

In the editor, If I switch an “Trigger” from “Twitter” to “Instagram”, I still see a property from the Twitter schema (“track”). I don’t think that should be displaying at all, but it is also not displaying correctly. Is this a bug? In any case is there any way to get around this problem?

You can see what I mean here… http://jeremydorn.com/json-editor/?schema=N4IgLglmA2CmIC4QGECGZXQJ4GcwAJkB7AOwDMIBzAVwCd0JSQAacLAB3iSICMArWAGMwLEO1pFOtSLByJQYWlUqxachAo5cQqWvSyiyRWgFt0icKh5zWkGNoAqSyirWiosE+oVQ4Fp8qqoqSwAPJkiADaPvb+AO5QYEG2Wha8AsKi4pKqMt7g9IIA1vJsnBZ4SiSUogAmsoJK7JBMSMQmZvj10BAmHrX4PXj4RGT4SaY440TjhUUAdCAAvivMMX5IAJIkeKiU9CaiYKnc/EIirNlSeaUYlPl2GyAOezZl2rr6hsZmIkgYPD8rHqOEaEGajBIFgAMhBhmAABawfAI1A4BF3KZgGaKVDFRasagkCAAR2osE2SS8iEU5NYHmpGnAvm0dyOJxAlQg1WWKyWAF0+UsgAAA==&value=N4IgLgTglg5jCmEDOIBcBtUkCGBjA1miCAL4C6JQAAA=&theme=bootstrap3&iconlib=bootstrap3&object_layout=normal&show_errors=interaction

In the dropdown, change twitter to instagram.

It’s not a bug, but it is really unintuitive behavior. By default, JSON Editor tries to keep the value of oneOf fields when you switch between schemas if possible.

You can fix this in one of two ways:

1. Make the track property invalid for your Instagram oneOf schema by setting additionalProperties to false.

{
  "title": "Instagram",
  "type": "object",
  "additionalProperties": false,
  "properties": {
    "tags": {
      "title": "Tags",
      "type": "array",
      "format": "table",
      "items": {
        "title": "tag",
        "type": "string"
      }
    }
  }
}

1. Turn off this default JSON Editor behavior by setting the option keep_oneof_values to false during initialization.

new JSONEditor(element, {
  schema: {...},
  keep_oneof_values: false
});
