Google Earth Community: Problem using view-based refresh.

I have a problem with view-based refresh. The problem is that it refreshes the complete tree structure when I only want to refresh a certain branch. The branch is a networklink on which the refresh is set.

It works fine when I use:
<refreshMode>onInterval</refreshMode>
<refreshInterval>1</refreshInterval>

but

<viewRefreshMode>onStop</viewRefreshMode>
<viewRefreshTime>1</viewRefreshTime>

refreshes the complete tree.

The document looks something like this:

<kml xmlns=\"http://earth.google.com/kml/2.1\">
<Document id=\"document\">
<name>My Application</name>
<Folder id=\"Entities\"><name>Entities</name>
<Folder id=\"Land\"><name>Land</name></Folder>
<Folder id=\"Air\"><name>Air</name></Folder>
</Folder>
<Folder id=\"Life form\"><name>Life form</name></Folder>
<NetworkLink>
<name>Dynamic</name>
<Link>
<href>http://www.bbbbb.com/dynamic</href>
<viewRefreshMode>onStop</viewRefreshMode>
<viewRefreshTime>1</viewRefreshTime>
</Link>
</NetworkLink>
</Document>
</kml>

A request to http://www.bbbbb.com/dynamic will cause my web server to return updates on some of the entities in the folders.

Does anyone know what I do wrong, if it is a bug, or maybe experienced the same?

Kind regards,
Clarence
