Hi @ismirsehregal

Did you identify the reason for which I commented out the line? Because I don't want to restore this line if I don't know this reason.

Hi Stéphane, it seems you haven't actually commented it out. The (commented) line was added with this commit (triggered by this issue) (see the diff - nothing was deleted. Maybe it was just for testing and you haven't noticed any difference?).

However, if you rather want to keep using the select_node.jstree and deselect_node.jstree events instead of changed.jstree, we could add listeners for select_all.jstree / deselect_all.jstree as an alternative solution. Although, I haven't noticed any issue using changed.jstree and it seems to be the recommended way as it covers all cases.

Hi Stéphane, have you had the chance to test this? Cheers

My main laptop is dead. Now I only have an old one (with Windows 7) and I don't like to work on this one. But I will.

Okay - thanks for the update! Please let me know if there is anything I can do to help. Cheers

Yes you can ;-) Tell me whether there's a nice IDE for R that works with Windows 7. I really miss RStudio.

Uh 🙈... that's bad.

Maybe you can downgrade:

..or once I installed RStudio Server on a Raspberry Pi 😅

Hi Stéphane, I just wanted to leave a frindly reminder, that it would be really helpful if this is merged (or the alternative approach mentioned above is implemented).

Cheers
