Context:
I'm a junior developer and I was assigned to a project that uses bryntum gantt. I have little experience in the business but I already understand some things. Before I was allocated to this project, several other developers modified the code. So there are several bugs and I need to resolve one in specific.
Version: Bryntum Gantt 2.1.4
The Problem:
When associating a resource, I can define the percentage value of that resource. However, when typing the value and leaving input, the box should be automatically marked and the value in the unit column("ALOCAÇÃO%") should add a '%' to the end. But this isn't happening.
From what I researched, this behavior should happen by default. Is it possible that a bug made by an old developer broke this functionality? Where to start looking for the bug?
