Do you know if a method exist to be informed that Oxygen start-up is really finished ?

[sebastienlavandier]

Hi,

I receive a nullPointerException from Oxygen, when I try to make a PluginWorkspaceProvider.getPluginWorkspace().open("projectFile.xpr") on my custom WorkspaceAccessPluginExtension on applicationstarted() method.

I think Oxygen is not really started...
When Oxygen start-up is really finished, I can open a project file by the same way... (PluginWorkspaceProvider.getPluginWorkspace().open("projectFile.xpr"))

So, do you know if a method exist to be informed that Oxygen start-up is really finished, and is ready to work ?

Thanks in advance for your help.
Sébastien

Hi Sébastien,

If you have the stack trace for the NullPointerException, please post it, because I cannot reproduce this with the sample XPR I tried, it probably depends also on the options that you have stored at project level.
Indeed opening the XPR on that callback might be too soon, we have not tested doing this before, as a possible workaround maybe you could use javax.swing.SwingUtilities.invokeLater(Runnable) or start a java.util.Timer which triggers a task after a second or two.

Regards,
Radu

Hi Radu,

I Send to you the stacktrace :

Code: Select all

L'application a détecté une erreur qui n'est pas traitée automatiquement. Il est possible que cette erreur ne soit pas critique et que l'application puisse continuer à fonctionner normalement, mais notre recommandation est de signaler l'erreur et redémarrer l'application. Si l'application est devenue instable et ne peut pas être fermée normalement, vous pouvez utiliser le bouton Forcer la Fermeture de cette boîte de dialogue. Soyez conscient que, ce faisant, vous perdrez toutes les modifications non enregistrées dans les documents ouverts.



Voici les détails de l'erreur:

Hi Sébastien,

Could you tell me what version of the Oxygen you are using? We fixed a similar NPE in Oxygen 17.1.
If you are using 17.1, it would be great if you could attach the XPR you are using to an email, then we could look into it on our side.

Regards,
Radu

[sebastienlavandier]

Hi Radu,

We use the 17.0 version !

[Radu]

Hi Sébastien,

Then you can either upgrade or use a java.util.Timer to postpone the loading of the project for a second.

Regards,
Radu

[sebastienlavandier]

Hi Radu,

Can we use the V17.X with our licence ?

[Radu]

Hi Sébastien,

Any license key which works with 17.0 should work with 17.1.

Regards,
Radu

[sebastienlavandier]

Hi Radu,

YES !
It works fine with 17.1.
Thank you for your help.
