Crashing when changing the selection of parent.

[reenaphilip]

Rarely i am getting the below crash.
'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (10) must be equal to the number of rows contained in that section before the update (10), plus or minus the number of rows inserted or deleted from that section (2 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

I am using sampleTreeView.collapseNoneSelectedRows = true

How to fix this?

Any updates ?

Is this library maintaining?
Please update so that I can use it in my project.
Here is the scenario of crash

1. Set sampleTreeView.collapseNoneSelectedRows = true
2. Select a parent node without children
3. Select a parent node with children. This will open the child nodes.
4. Select another parent node with children .
   Now the app crashes.
   the crash log is
   'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (10) must be equal to the number of rows contained in that section before the update (10), plus or minus the number of rows inserted or deleted from that section (2 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

I am directly adding the files instead of using pod.

Please update or else I am compelled to change the implementation

@reenaphilip Hi! If it is still relevant for you, I found the answer

CITreeViewController's collapseRows method

func collapseRows(for treeViewNode :CITreeViewNode, atIndexPath indexPath:IndexPath) {}

contains the following code

if treeViewNodeChildren.count > 0 {
    treeViewControllerDelegate.willCollapseTreeViewNode(treeViewNode: treeViewNode, atIndexPath: indexPath)
    setCollapseTreeViewNode(atIndex: indexPath.row)
}

You should change it to

if treeViewNodeChildren.count > 0 {
    treeViewControllerDelegate.willCollapseTreeViewNode(treeViewNode: treeViewNode, atIndexPath: indexPath)
}

setCollapseTreeViewNode(atIndex: indexPath.row)

It works for me with sampleTreeView.collapseNoneSelectedRows = true, hope it will hep you.
