[SOLVED] Sencha Extjs 7.7.0: pop-over is not displayed in grid component that contains combo box editor (cell editor)

In extjs version 7.7 pop-over is not displayed in grid component that contains combo box editor (cell editor)

While this problem does not exist in the previous version 7.6 .

There is also this problem in the example of the Kitchen Sink (Classic).

This bug will be fixed in the next version, but Sencha does not have an ETA.

Until issue gets fixed in the official framework , please use the below override as a temporary workaround.

Ext.define('null', {
    override: "Ext.view.Table",
    focusPosition: Ext.emptyFn,
});
