When my KML file is reloaded all layers insided the file are selected/displayed again

[IDontKnow]

Every time my KML file gets reloaded all the folders/Placemarks are displayed again.
Even the ones that I have unchecked in the Layer Tree.

I am using a NetworkLink to upload the file every 5 seconds.

What code do I change to loop through the old kmlRoot and update the new kmlRoot with the user preferences of being displayed or not?

Hope that makes sense Thanks.

I am using the KMLViewer example

Found it.

KMLLayerTreeNode.java

refresh()

I added code to remember the child isSelected state
Then in the call to addChildFeatures called setVisibility with the previous state.
