- if you load components object instead of pageManager you will get the same result

What is the expected behavior? after saving and loading pages object, it convert whitespace to "null" and it shows "null" instead of whitespace.
What is the current behavior?
And to see nulls on the page u should export page using grapesj-export plugin .
and exported page will look like this :
in brief, this is what cause the issue :
{ "type": "textnode", "content": null },
this issue appeared only in the latest versions grapesjs>v0.18.4
Note This issue is not from my server or even source code of the component itself

Hi @joukhar is it happening with the latest version?
I'm able to see nulls in the export code if I use your exact JSON example (that should be fixable), but I'm unable to generate those textnodes with nulls by using your HTML example, can you create a reproducible demo for that use case?
Not sure in which case the textnode might be null but for sure we can prevent that...
thanks for the replay, if you need demo so please give me some time until i make one , i will comment again when im finished it the problem happens only when u store it and load it, but when u drop the component for the first time nothing happened
Thanks for reporting this, @joukhar.
Great question about textnode with content "null" is rendered as "null" not whitespace. The recommended approach with ProseMirror is to use the event-driven API.
Start here:
- Check the GrapesJS documentation for your specific module
- Look for the
on()event listener method - Most operations can be achieved by listening to editor and component events
Common patterns:
// Listen for changes
editor.on('change', () => console.log('something changed'));
// Component lifecycle
editor.on('component:mount', (c) => console.log('component ready', c));
editor.on('component:update', (c) => console.log('component updated', c));
If you're still stuck:
- Share a minimal CodeSandbox reproduction
- Include what you've already tried
- Mention your GrapesJS version
