Editor misbehaves after entering link

[wwwald]

Running Trilium 0.45.4 on Windows 10.

Quite regularly, I notice that the editor becomes partly unresponsive and does not save entered text anymore, usually right after entering an internal link by typing @. I need to refresh Trilium (Ctrl+Shift+R) to get it working normally again.

The JS Console shows these exceptions:

VM426:5 Uncaught TypeError: Cannot read property 'getStyle' of null

    |     property 'model' -> object with constructor 'Fl'

    at JSON.stringify (<anonymous>)
    at window.onerror (glob.js:60)

Any clue what could be causing this?

Hello, I noticed this as well. I think it's a CKEditor bug, although I can't say that with certainty ...

Well, there is issue ckeditor/ckeditor5#4959 on circular references and JSON.stringify... but it's been open since 2017.

Do you think that this is the same problem we're seeing here?

Adding another example of CKeditor not handling URLs very well! Seems to be a similar symptom but not sure if the root cause is the same. (It won't save a document if I try to enter additional info to a previous bullet point after I add a link - but it does work if I add information in an unrelated field).

Looking up the error codes result in https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-model-nodelist-offset-out-of-bounds and https://ckeditor.com/docs/ckeditor5/latest/framework/guides/tutorials/implementing-an-inline-widget.html#fixing-position-mapping

Unfortunately I am not entirely familiar if this issue can be fixed in Trilium or if I should open a new issue over at CKEditor, but hope this helps a bit!

For anyone else suffering from the same issue, using ctrl + k to enter links is also a possibility (and possibly cleaner). :)

Trilium 0.45.7 Linux Server.

Hi, I'm suffering from this too. For me the error seems to me Uncaught CKEditorError: t.viewItem.parent is nulland refers to https://ckeditor.com/docs/ckeditor5/latest/framework/guides/support/error-codes.html#error-t.viewItem.parent. But I have also experienced the model-nodelist-offset-out-of-bounds error mentioned by @WKSu. Seems to happen to me both in Firefox (server edition) and in the desktop edition.

I don't see this erratic behavior anymore with the new 0.48 version.

The 0.48 release notes mention that CKEditor was updated to version 30 - I'm guessing that that has solved the problem above.

Time to close the issue?

Thanks for confirmation, closing.
