[Gantt Chart] Demo Error - $ is not defined
gantt-chart
Reactive icon
Forge asset by Tan Vo Minh
Application Type
Reactive
Service Studio Version
11.55.26 (Build 64206)

Hello,

While trying to run the demo provided I ran into the error "$ is not defined" as soon as the screen loads. I have elementary knowledge on JavaScript and was not able to find the issue.


Any ideas?


Best Regards,

Juliano Prisco

Hi Juliano,

The component relies on jQuery, which was previously included in the OutSystemsUI scripts. However, starting from version 2.14.0, OutSystemsUI no longer includes the jQuery library by default. 

To restore the component's functionality, you can manually add a jQuery script to the module’s Scripts folder. I tested it with jQuery version 3.7.1, and it worked as expected. 

You can find an updated version of the component attached below.
