why does the AbstractPreferenceInitializer never get called? [message #321714]

WinXP, R3.3 (I20070621-1340)

Several prior threads insist that the AbstractPreferenceInitializer will
automagically get run when it is needed. See:
"How to load default preferences ?"
"Setting the default values for preferences"

But when I declare an AbstractPreferenceInitializer like this (actually,
I used the template in the extension-point wizard):

<extension
point="org.eclipse.core.runtime.preferences">
<initializer
class="com.mun.ist.viewer.preferences.PreferenceInitializer ">
</initializer>
</extension>

and implement the sole method of PreferenceInitializer, setting a
breakpoint on the method shows that it is *NEVER* called, not even when
I open the pref-page, and certainly not when I access the preference-value.

So -- what else needs to be done to wire this up? (The extension-point
description says nothing about extra wiring.)

The workaround -- in case others are having this problem -- is just
this, in the Activator:

public void start(BundleContext context) throws Exception {
super.start(context);
new PreferenceInitializer().initializeDefaultPreferences();
}

thanks,
Paul

I experienced the same problems but it worked fine after adding

IPreferenceStore store = Activator.getDefault().getPreferenceStore();
setPreferenceStore(store);

to the preference page constructor.
