DOMException in onrender when column name has a space

[DanielRose]

Create a column definition where the column name has a space, and add an onrender function:

{ name: "or der", label: "Order", onrender: function(task) { return task.order; } }

This throws a DOMException, because the generated querySelector does not properly escape the column name:

Uncaught DOMException: Failed to execute 'querySelector' on 'Element': '[data-column-name=or der]' is not a valid selector.

In the codebase:

  function onrender(item, rowNode, view) {
    var columns = view.getGridColumns();

    for (var i = 0; i < columns.length; i++) {
      var column = columns[i];

      if (column.onrender) {
        // find cell node for current column
        var cellNode = rowNode.querySelector("[data-column-name=" + column.name + "]"); // <---

@DanielRose, thank you for reporting the bug! It seems to be working that way since the 7.1 version.
I added it to the internal bug tracker. The dev team will fix the bug in the future, but I cannot give you any ETA.
As a workaround, you can try using the underscore symbols instead of the spaces.
