ConfigurationScope is not working [message #645600]

Hi Experts,

I tried the following code and it works as expected:

IScopeContext configContext = new InstanceScope();
EclipsePreferences configurationNode = (EclipsePreferences) configContext.getNode(Activator.PLUGIN_ID);
configurationNode.put(key, value);
saveNode(configurationNode);

So that the preferences are stored correctly and have a workspace scope.

My problem comes with the ConfigurationScope:

IScopeContext configContext = new ConfigurationScope();
EclipsePreferences configurationNode = (EclipsePreferences) configContext.getNode(Activator.PLUGIN_ID);
configurationNode.put(key, value);
saveNode(configurationNode);

The code is executed successfully and I can see the contents of the configurationNode. But once I restart Eclipse, everything is gone.

Do you have any idea what can be missing ?

Thanks

Are you in a multi-user install, or any install where the configuration
area is read-only?

new ConfigurationScope().getNode(PLUGIN_ID) and using get and put seem
to be enough for other examples.

Hi Paul,

Thank you for your reply.

I actually have found that the problem occurs only when I run a new instance of eclipse from inside my Dev eclipse (in order to debug my code)

When I run it as a standalone eclipse it works fine.
