I have upgraded a huge project we have, from Kendo UI 2017 to the latest version.
I managed to fix all the incompatibility issues that I had with the latest version and now it's ready to go live.
In the final regression tests our customer found a bug and now we are stack and cannot deploy the project.
Here is the problem:
In the DropdownList, if you type something and then press the clear button, the change event is firing two times. One with the value that you typed before and then one again with an empty value (the right one). The biggest problem is that there is no way to determine that the first event is coming from the clear button and not from the user, so I cannot find any workaround this.
I searched and I found that this started after this change.
You can check this dojo for a reproduction of the problem.
Steps:
Type "it" in the dropdownlist,
Wait for the items to popup
Don't select any item but press the clear button of the dropdownlist
You can see the attached image the wrong events.
If you select a version after 2019 R3, the change event is firing twice. If you select an older version the change event is not firing at all.
I can understand a change event with an empty value and I don't have any problem with that, but the first event is totally wrong.
Is there any quick solution to this so we can catch the deadline and deploy the new version of our project?
Thank you for your time,
John Dendrinos
