Issue/Introduction

If you try to drag an instance in a Hierarchy in the Timeline view, a "forbidden" icon appears in the investment. After releasing the mouse, the action is in progress and remains unless you click on a new position for that instance. If that new position changes the parent/child structure of the hierarchy, you get the following error:
'Attribute(s) 'parentTask' are not supported.' or 'Attribute(s) ‘nextSibling’ not supported.'.

Steps to Reproduce:

1. Create a new hierarchy (e.g.: type: Investment)
2. Import some investments to the hierarchy.
3. Navigate to the Timeline view.
4. Drag any item (hold the mouse button) by the investment name. The mouse cursor will turn into a 'forbidden' icon.

Expected Results: The drag and drop action does not start, i.e.: it is 'forbidden' (OR: drag and drop action starts and continues while holding the button only).

Actual Results: The drag and drop action starts, and even after releasing the mouse button, it continues (again unexpected) unless it is actually clicked again to a new

position.

5. Move the instance so that it is a child of an existing instance.

Expected Results: Move action should not have started (OR: the instance is now a child instance).

Actual Results: 'Attribute(s) 'parentTask' are not supported.' error is displayed.
