Error message with treeview on Debug version

[Duy-NV-Niteco]

Hi everyone,

Currently, i am working on CC 2015 Debug version.

I meet a message like the attached image.

After debugging, it relates to funtion GetChildIndex()

But i dont know where i am wrong?

Did anyone meet this one before?

Thanks.

Hi Duy-NV-Niteco,

I think there is an error in your implementation of ITreeViewHierarchyAdapter. The function ITreeViewMgr::IsNodeExpanded tranverses from its node up to the root node to check if all nodes are expanded, but the functions of ITreeViewHierarchyAdapter are not consistent, i.e. GetChildIndex(parent, child) returns -1 or an index, but GetNthChild(parent, index) does not return the same child node.

InDesign checks this consistency of ITreeViewHierarchyAdapter in debug mode.
