workbench.xmi not updated? [message #1268490]

Hello,

I have an E4 app that updates itself at startup, based on an update site.

Today I corrected a bug related to key bindings, and pushed a new version. The app correctly updated itself at launch but the bug was still there.

I finally found out that by deleting the file located at ".metadata/plugins/org.eclipse.e4.workbench/workspace.xmi" and restarting, the bug disapeared.

What are the rules that trigger the creation of a new workspace.xmi file? Is it something that I can force at startup time?

Thanks for your help,

Sébastien

Use -clearPersistedState option.

Hi,

Thanks for your answer.

It's true that using the option to clear the persisted state solves the problem, but I'm not going to ask my users to do it. It's a technical operation they do not need to worry about.

The situation here is that I deploy a new version of the app but the old version's XMI is still used. What should I do to prevent that?

Open you product and you can add this option under Launching Argument. See the below image.

I think he generally wants persist the state and not clear it always, so
what he needs is a way to clear it only when the application is updated.

I don't think there's a general solution in place for e4 and one has to
develop ones own. A custom solution I could think of is to use the
lifecycle PostContextCreate and proactively remove the workbench.xmi
when an update is detected on the first start after the update.

I think that we (=e4) should provide a general solution to this problem
so I'd like you to file a bug and ask for a solution provide by the
framework!

Thanks Thomas, I'll do that right away. Where should I open it? Platform/Runtime? Or E4/Runtime?

I think Platform/UI is the right component
