Hello all

On my page I have a tree view. The source is dynamic and serialized at runtime. When I select an item the selection property is correct set:

```python
[
  "1/0/0"
]

```

The moment I stop the preview mode (to design mode) and go back to preview mode the selection is not shown within the tree even though the selection property is still correct set. Do you have any advice or is this a known bug?

PS: I can also reproduce this behavior by just placing the tree view and use the example data.

In the Designer and the Browser

Can you describe the behavior of what happens in the browser ?  
In the first post you only mention going in and out of preview mode, which doesn't apply to browsers.

Opening the web page and clicking inside the tree view the selection is set, like on the picture above. When I do a reload of the page the selection is not shown even though the selection property shows correct values.

I've seen this same behavior. No help for it, that I know of.
