Error running BIRT report via Tomcat [message #134569]

Hi,
I'm using Eclipse Galileo M7, RAP 1.2 and BIRT 2.5.
When I try to open a report design from my RAP application (so that I can
then run the report), I get the following error

SEVERE: Could not execute
org.eclipse.ui.internal.Workbench$ShutdownHandler.beforeDest roy(SessionStoreEvent).
java.lang.NullPointerException

I've implemented user preferences by following the example provided in
org.eclipse.rap.demo i.e. adding a preferencePages extension point, adding
a PreferencePage class, then setting the preferencestore using the line
setPreferenceStore(PrefUtil.getAPIPreferenceStore());

Is there something I've missed? It works fine when I run the application
from Eclipse, but I get the error when I deploy it in Tomcat.
Any help would be much appreciated!

In my investigations I've tried adding a preference initializer to see
whether it made a difference or not. However, I can't

get the initializer to work.

I've created a preference initializer class and added an extension, my
plugin.xml contains the following

<extension
point="org.eclipse.ui.preferencePages">
<page
class="MyPreferencePage"
id="MyPreferencePage.id"
name="My Preferences">
</page>
</extension>
<extension
point="org.eclipse.core.runtime.preferences">
<initializer
class="MyPreferenceInitializer">
</initializer>
</extension>

When I run the application, the default preferences don't appear e.g. if I
click the "Restore Defaults" button from the Preference Page.

Is there something else I need to do in order to get the preference
initializer to work?

the stack trace indicates that the exception occurs while the
session is invalidated. Are you sure that the exception is a direct
consequence of opening a report?
