Typed or Copied Content Replaces Custom Alert Block Instead of Staying Within It

[lamtuanamc]

Description:
I have customized a block type "alert" followed by a custom block on the BlockNote homepage.
However, every time I type '-', '*', '+', '1.' or copy a text segment within the same editor, it replaces the "alert" block instead of placing the content within it.

Steps to Reproduce:

1. Create a custom "alert" block as per the documentation.
2. Type '-', '*', '+', '1.' or copy and paste a text segment within the "alert" block.
3. Observe that the content replaces the "alert" block instead of staying within it.

Expected Behavior:
The typed or copied content should remain within the "alert" block instead of replacing it.

Actual Behavior:
The "alert" block is replaced by the typed or copied content.

I agree this is undesirable. It should probably be fixed here:

BlockNote/packages/core/src/blocks/ListItemBlockContent/BulletListItemBlockContent/BulletListItemBlockContent.ts

Line 49 in bea361e

if (getCurrentBlockContentType(this.editor) !== "inline*") {

(and in the code for related shortcuts)

@YousefED If I remove this line, won't the regular text lines be unable to trigger the creation of a list? Or is there a way to check so that other blocks are not affected?

You might want to call getBlockInfoFromPos instead and check if the block type is part of the default blocks:

const { contentType } = getBlockInfoFromPos(
  this.editor.state.doc,
  this.editor.state.selection.anchor
);

if (contentType.name in defaultBlockSpecs) {
  return true;
}
