@contentful/field-editor-rich-text re-rendering problem

[giovanni-caiazzo]

Hi all,
I am using @contentful/field-editor-rich-text in a contentful app, version 2.1.0 and I have some problems with rerendering.
Basically I am rendering a set of tabs and each tab has an instance of @contentful/field-editor-rich-text:

<ConnectedRichTextEditor
sdk={sdk}
value={accordion.content}
onChange={(e: any) =>
setGlobalData((prevState) => {
    const newState = [...prevState];
    newState[idx].content = e;
    return newState;
})}
minHeight={"300px"}
/>

When the component first renders it works great, but as soon as I change tab, the editor disappears and never reappears even when I return to the original tab. When the page is reloaded the editor reappears, only to disappear again as soon as a new tab is selected.
I also tried to render all the editors together without tabs: what happens is that all the editors have the content of the last rendered editor, which is not ideal.

Here is the full Field component

const Field = () => {
  const sdk = useSDK<FieldExtensionSDK>();
  const [globalData, setGlobalData] = useState<AccordionData[]>(
    sdk.field.getValue() || [{ title: "", content: emptyRTF }]
  );
  const [currentTab, setCurrentTab] = useState("accordion-0");

  useEffect(() => {
    sdk.window.startAutoResizer();
  });

  useEffect(() => {
    if (globalData && sdk.field.getValue() !== globalData) {
      sdk.field.setValue(globalData).then();
    }
  }, [globalData, sdk.field]);

  return (

        You can create more than one accordion in this component. Use "Add
        Accordion" to create one. If you want to delete a particular accordion
        you can use the "Delete Accordion" button of the relative Accordion.

Is there something I'm doing wrong when rendering the editors? Or is this a bug of the editor? Version 1 did not have this problem using the same code structure, but it did have problems selecting the text and changing it.

Hi, I encountered the same issue with basically the same use case. After some debugging I tracked down the issue to the ids of the respective ConnectedRichTextEditors. Internally they are passed to the Plate component, which requires the ids to be unique. I was able to fix the issue by passing a unique id to our custom ConnectedRichTextEditor implementation which replaces the internal id calculation.

Unfortunately there doesn't seem to be a fix available without rewriting the internal rich text editor logic.

Thank you so much @niclaszllaudi for pinpointing the issue in the codebase. I have used patch-package to make it work. This however is NOT a solution to the issue and if the devs want us to make a PR I would happily do it. For now my project is not blocked though, which is great.

Can you share more about your use case @niclaszllaudi & @giovanni-caiazzo ?

For the internal ids calculation we use the entry key + field id + the locale code. So, in theory, it should only clash if you are rendering the same entry field for the same locale twice. Is that the case for you?

[giovanni-caiazzo]

Hi @z0al. In my use case I have a contentful app that is rendering a json field as a collection of rich text fields, each accessible with its own tab. I used patch-package to add a new prop to ConnectedRichEditor in order to add a custom ID appended to the ID you are creating like you described.

[niclaszllaudi]

Hi @z0al, we want to render two ConnectedRichTextEditor instances within the same field. This results in both being assigned the same id, causing the issue.
