Configuration Properties not defined in Metatype are lost after update

Web console when updating items that have metadata will only update the properties defines in metadata.

This means, the fileinstall file location is removed from the property update. This makes so fileinstall will no longer update the configuration
file with the change. A simple workaround is to always post back the fileinstall property if present.

In the ConfigAdminSupport.java file added these lines. In the method applyConfiguration at line 312, insert these lines:

// Add Fileinstall key or the property will not get written back to the configuration
if (props.get("felix.fileinstall.filename") != null)

{ updateProps.put("felix.fileinstall.filename", props.get("felix.fileinstall.filename")); }

If you return the fileinstall filename then fileinstall will save any property changes.
