PropertyChangeEvent event not consistent when passing values for preference [message #42742]

I am running on Eclipse 2.1 Build id: 200303272130

I have a preference page that extends FieldEditorPreferencePage and
therefore uses FieldEditors to present and set the values.

I am using IPreferenceStore in my plugin.

I have noticed an inconsistency in the values passed to listeners of
property change events.

If I change a field on my preference page (e.g. BooleanFieldEditor) and
press "Apply" I get a PropertyChangeEvent that contains a newValue and
oldValue that are "Boolean" objects.

BUT

When I press the "Restore defaults" button and then "Apply" I get a
PropertyChangedEvent that contains newValue and oldValue as Strings to
represent the values "true" and "false".

It appears to be a problem because of the attempt to map between the older
IPreferenceStore and the newer Preferences classes.

Is this a bug or am I not using the property event values correctly?

There is a bug report for this. Bug 9259 [Preferences] IntegerFieldEditor
returns inconsistent value types in PropertyChangeEvent. I will update it
to indicate that it happens for booleans also. You can add yourself to the
CC and vote for it, though its pretty low priority.
