"TypeError: Cannot read property 'type' of undefined" when deleting cells while cursor is over resizable column border

[ascott18]

1. With column resizing enabled, highlight two or more cells.
2. Without releasing your left mouse button and while your cursor is close enough to a column border to trigger a resize cursor, press the Delete key to delete the cells.
3. Observe the following error:

Uncaught (in promise) TypeError: Cannot read property 'type' of undefined
    at computeMap (index.es.js:273)
    at Function.get (index.es.js:268)

This is because pluginState.activeHandle is not being cleared/reset to -1 when its corresponding node is removed. Also because handleDecorations in columnresizing.js is not checking that table is not null/undefined before passing it to TableMap.get(table).

any possibility of this getting fixed? occurring for me as well when hovering over the resize cursor and undo'ing the history by pressing ctrl + z

[ianmcateer]

the fix is here, just added a check for !table

function handleDecorations(state, cell) {
  let decorations = [];
  let $cell = state.doc.resolve(cell);
  let table = $cell.node(-1);
  if (!table) {
    return DecorationSet.empty;
  }
  let map = TableMap.get(table);

  let start = $cell.start(-1);
  let col = map.colCount($cell.pos - start) + $cell.nodeAfter.attrs.colspan;
  for (let row = 0; row < map.height; row++) {
    let index = col + row * map.width - 1;
    // For positions that are have either a different cell or the end
    // of the table to their right, and either the top of the table or
    // a different cell above them, add a decoration
    if (
      (col == map.width || map.map[index] != map.map[index + 1]) &&
      (row == 0 || map.map[index - 1] != map.map[index - 1 - map.width])
    ) {
      let cellPos = map.map[index];
      let pos = start + cellPos + table.nodeAt(cellPos).nodeSize - 1;
      let dom = document.createElement("div");
      dom.className = "column-resize-handle";
      decorations.push(Decoration.widget(pos, dom));
    }
  }
  return DecorationSet.create(state.doc, decorations);
}
