Property :: positionHierarchy - Select hierarchy for property handle
The function ensures that all property handles in a hierarchy are positioned, i.e. an instance is selected for all upper property handles and the calling handle itself. When no instance is selected in a property handle in the hierarchy, the function automatically tries to position to the first instance for those property handles.
The function returns false , when positioning the hierarchy failed and true when selecting the path terminated successfully..
Return value: Success ( bool )
The value is true when the function was executed successfully. Otherwise the value is set to false .
