@globdug,
Usually, the cyclic tree error means that the task has equal id
and parent
parameters or some child task is listed as the parent task:
https://docs.dhtmlx.com/gantt/faq.html#cyclicreferenceerror
However, in DHTMLX Gantt there is an invisible root task that is a parent of all tasks on the root level.
So, when you add a task with the 0
ID, it is assigned to the invisible root task, and its parent
value becomes 0
. So, it creates the cyclic tree.
To have a task with the 0
ID, you need to change the root_id
config:
https://docs.dhtmlx.com/gantt/api__gantt_root_id_config.html
Here is an example in the snippet: https://snippet.dhtmlx.com/vle0qtkd
Hello, I'm trying to import data from XML exported from MS Project.
Project's tasks ID start from 0, but if task ID is equal to 0 in the JSON file then I got the error "Error: Invalid tasks tree. Cyclic reference has been detected on task 0".
Is this a bug or an expected beheaviour?
Best regards, Emanuele
