| Need to reset a plugin back to INSTALLED state [message #528440] |

Hi,
We have a plugin which contributes views, menus (via Command extension)
and StatusBar updates.
The plugin needs to be able to be stopped if commanded by the user, and
returned ideally to either the INSTALLED state or the lazy start state.
I found I can use this approach to get the plugin to stopped state but
the contributed resources are still available even though they can do
nothing since the plugin has stopped:
Bundle bundle = Activator.getDefault().getBundle();
bundle.stop();
It's also possible to bundle.uninstall() but how do we get the plugin
reinstalled?
Thanks for any suggestions,
Dilton

Thanks for clearing things up for me Paul. I've verified
the refresh part using the OSGi console by adding -console
to the Run Configuration.
I still need to figure out how to get Eclipse to re-install when
the user wants to work with the plugin again, perhaps your
suggestion on how test utilities do it is the right way to go.
Perhaps I'll add a starter plugin that the user uses to start the
main plugin.
Thanks for the tips.
