Steps To Reproduce:
We are building our own common navigator by extending the CommonNavigator class.  We declare filters both declaratively in plugin.xml and programmatically, so that some filters are always enabled and some can be customized by users.  

What we found was whenever filter selection are changed from Available Customization dialog, all filters associating with the Common Navigator will first be reset then set according to the selection made in the dialog.  

Hence, all the filters that were added programmatically will be disabled.

1. Declare a new class that extends the CommonNavigator class, and programmatically add filters to the CommonViewer
2. Declare an instance of the org.eclipse.ui.navigator.viewer extension point using the new class
3. Declare other filters declaratively in plugin.xml
4. Make filter selection changes on the Available Customization dialog, and you will see all programmatically added filters are removed.
