draft-js Cannot read property 'getIn' of undefined ( getUpdatedSelectionState )

Question

I have this error with draft-js with draft-js-plugins-editor

STRANGE BEHAVIOR: it only happens, when I refocus to first line of editor after writing, when trying to set for eg. the header of first line to H1 it changes previous focused line

ERROR: Uncaught TypeError: Cannot read property 'getIn' of undefined

This is my component:

  UnderlineButton,
  HeadlineOneButton,

  HeadlineThreeButton,
  UnorderedListButton,
  OrderedListButton,
  BlockquoteButton,
} from 'draft-js-buttons'




export default class TextArea extends Component {

My component looks like this:

Answer 1

I meet the same problem. It looks like because call editorState.getBlockTree(anchorBlockKey).getIn(...) in getUpdatedSelectionState.js the editorState.getBlockTree(anchorBlockKey) is undefined whenever the block type is unstyled.

I have no idea how to fix it, so make a work around solution like this:

const headerOne = '<h1>Title</h1>';
const blocksFromHTML = convertFromHTML(headerOne);
const state = ContentState.createFromBlockArray(
    blocksFromHTML.contentBlocks,
    blocksFromHTML.entityMap
);
this.state = {
    editorState: EditorState.createWithContent(state)
}

But there will be another problem when you press enter new line will be H1 either.
