getTreeFromFlatData prevent children to be overriden in trav function

[pinkbunny1]

getTreeFromFlatData() the children property when the root parent has children where one of them can be subParent. for example where folder has many reports and subFolder which has its own reports.

When flat list item parentId refers to id of another item in the flat list but it also has children property and value of its own, it should be added to the children list instead of overriding it.

When running this data with getTreeFromFlatData(), you can see that object with id 7, its children is replaced with id 8 which has parentId as 7. But it should be that the children of id 7 should have its original children value intact and add the object id 8 into its children's list.

Hi, @pinkbunny1
Is this related to the sorting not being correctly rendered using the getTreeFromFlatData function?
I have the issue where moving nodes at the same level are not correctly sorted after you refreshed the browser, take this as an example, you have the following tree:

-- parent
    |__ children_1
    |__ children_2

and let's say you move children_2 from its position, like this:

-- parent
    |__ children_2
    |__ children_1

after moving the node, I'm able to update the node in the DB, but once I refresh the browser the tree is reverted back as it originally was, like this:

-- parent
    |__ children_1
    |__ children_2

To load the tree I'm using the getTreeFromFlatData to transform the DB data into tree data.
I cannot get this working. Doesn't matter what I do, the sorting is never saved in the database.
