TreeMightBeCyclic

Text

Tree is {0} levels deep. This might indicate that the accessibility tree is cyclic, and thus it would appear to be infinite.

Type

Error

Description

The element tree is cyclic and the tree depth might be infinite.

This issue causes problems for people who rely on a screen-reader and keyboard for navigation because there will be no apparent limit to the traversal of elements in the target application.

Possible causes

Multiple elements, or their parents, are custom controls that do not implement tabbing correctly. For example, the MSAA State property is not updated correctly.
