[Mentions] cannot remove mention with backspace

If I try to delete mention, this error occurs:

Uncaught Invariant Violation: Unknown DraftEntity key.

I’ll try to create sample project later, if it’s necessary.

I had the problem while working on a fork of the project. I had accidently run npm install in a plugin directory. There was two versions of draft-js: one in the root of the project, one in the plugin directory. So when I was creating a new entity in the /doc folder, it was creating an entity in the root draft-js library, and in the plugin it was trying to retrieve it from the local draft-js lib. I just deleted the local node_modules (in the plugin dir) and it worked.

@MarkNijhof,I got this error too.As @theuniverse said ‘the root cause is there are 2 modules of “DraftEntity” in the project’.My project had two modules.I find draft-js in ‘draft-js-mention-plugin/node_modules’ ,so, webpack build draft-js twice in bundle file.

You could update your draft-js as draft-js-mention-plugin use. These are dependencies draft-js-mention-plugin used.

  "dependencies": {
    "decorate-component-with-props": "^1.0.2",
    "draft-js": ">=0.8.1",
    "find-with-regex": "^1.0.2",
    "immutable": ">=3.8.1",
    "lodash.escaperegexp": "^4.1.2",
    "react": ">=15.2.1",
    "react-dom": ">=15.2.1",
    "union-class-names": "^1.0.0"
  },

so, I update draft-js to ‘>=0.8.1’

"dependencies": {
    "antd": "2.0.1",
    "chai-shallow-deep-equal": "^1.4.4",
    "classnames": "2.2.0",
    "deep-equal": "1.0.1",
    "draft-js": ">=0.8.1",
   …
}
