Autocomplete issue with "(" and "&" characters

[tamsler-valtech]

Expected Behavior

A user can enter the characters:

• "(": Open parenthesis
• "&": Ampersand

Actual Behavior

These keys work as arrow down "(" and arrow up "&". The reason is this:

• In Ascii, 38 decimal represents ampersand, whereas the keyCode on KeyboardEvents is arrow up
• In Ascii, 40 decimal represents open parenthesis, whereas the keyCode on KeyboardEvents is arrow down

Reproduce Scenario (including but not limited to)

Using a Swiss German keyboard layout, add an Coral.Autocomplete field with some items and try to enter either "(" or "&" in the text field. If you have a suggestion list, these keys will navigate up and down the list.

The exact line of code responsible for this:

coral-spectrum/coral-utils/src/scripts/Keys.js

Line 385 in 9e2cc7f

comboListeners = this._keyListeners[event.key.charCodeAt(0)];

This also happens in AEM 6.5.8 and probably all 6.5 versions.

Thanks for the Analysis. I was also able to reproduce this on cloud-210600, so it affects AEM Cloud installations as well.
