Resource Grid issue when unfolding node

Gantt
#1

I initially created a resource datastore and then filled it with some resources. The display works and calculates everything correctly.

Then I have reset the gantt with clearAll() and removed all tasks. This also removed all resources from the resource datastore.

Now I loaded new tasks, which automatically bring new resources with them, which I saved in the resource datastore. The display works fine at first:

But when I try to unfold department 3, I get the following error:

Hello Yannick,
Unfortunately, I couldnā€™t reproduce the issue:

And it is hard to suggest what might be wrong as I donā€™t see your code. Please, reproduce the issue in the snippet, then click on the ā€œShareā€ button and send me the link. Or send me an HTML file with all the necessary Javascript and CSS files.

Hello ramil,
I was able to reproduce the error in your snippet, here is the link:

It is important that you load different resources and not the same resources every time!
Try the following steps:

  1. Open/Close/Click some resources in resource grid
  2. Clear data
  3. Load resources
  4. Open/Close/Click some resources in resource grid
  5. Clear data
  6. Load resources
    And so onā€¦

The snippet again gives me the following error message:

Hello Yannick,
Thank you for sending the snippet. Looks like the issue occurs because Gantt wants to unselect a resource and if there are different IDs, it fails.
I will add it as a bug in our internal tracker, and the dev team will fix it.
Unfortunately, I cannot give you any ETA, but here is a workaround:
Unselect the row before using the gantt.clearAll() command:

gantt.getDatastore("resource").unselect()

Here is the updated snippet:

Hello ramil,

It looks good. Since I use the unselect method I donā€™t get an error anymore.
Nevertheless I still have the question: When will there be a documentation of the datastore api?

Hello Yannick,
Unfortunately, I cannot give you any ETA, but I reminded the dev team about it.

Hello Yannick,

The dev team fixed the bug with the resource ID selection:
https://docs.dhtmlx.com/gantt/whatsnew.html#7012
Now, if you select a resource and load a new resource dataset, clicking on another resource row doesnā€™t cause an error.
You can check how it works in the following snippet:
