Hi Bryntum team, I'm having a problem with the "Id collision" error.
Currently I am using the Tree Grid format like the example here: https://www.bryntum.com/examples/grid/tree/.
First, I used the sample here: https://bryntum.com/examples/scheduler/grouping/ then in my code there was only resourceStore.add (array_resources) when the data was added. But since switching to TreeGrid I get "Id collision" error. I've been looking for some solutions to fix this problem, but it's not done yet. I know ID must be unique so I want that when I execute add() function you can check if ID exists or not?. If yes then execute, if not then stop? Is this possible?

You can simply run getById to find out if the record already exists before you add?

@mats Thanks a lot. You saved my day
