Hi, I follow the documentation about un-selecting an item in a treeview, like this: 

 

ktv.select($());

After, if I call ".select()", there's no node returned.  And, if I search for k-node-selected", there's also none.

BUT

the node with id "(id-of-treeview)_tv_active" is still there.  And, because we used it for some query, we got errors.

When we create a treeview from a div called <div id="test"></div>

The selected node gets its ID set to id="test_tv_active".

First, I don't think you should use an "id" for that.

And, you can fix the "unselect" by also removing the id from that item when we un-select it.

Hi Frederic,

Thank you very much for the feedback. We always appreciate any feedback that could be helpful to improve our widgets.  

The "treeview_tv_active" id is not removed when there is a focused node. Here is a Dojo example where the selection is cleared on a button click. As you will see even if the "bar 2" node is selected and then the selection is cleared, the first parent node will be focused. 

In case you need to remove the _tv_active id, you could do it by using the jQuery removeAttr method as below:

$("#treeview_tv_active").removeAttr("id", "treeview_tv_active")

I hope the above helps. Let me know in case you have additional questions or comments on the matter.

Regards,
Neli
