I found an error in the code.
The error gives when we use the Event of supposed click of an item in the list of the query.
I solved the problem by removing the call from the event on OnChange_TextInput
Hi Eduardo!
Thank you for reaching out and for wanting to contribute to the component.
However, the OutSystems UI team earlier released a version of the OutSystems UI library which has a new widget named "DropdownServerSide".
I believe this new widget will have better implementation across all different devices, and since OutSystems UI is an OS supported forge component, issues identified on its widgets can be reported to the same team and OS will work on fixing those.
I also accepted your request to join the team, but I must enforce that I see this component as really outdated and was considering deprecating it due to the reasons I mentioned above.
Kind regards,
Nuno
