Description Erik Damrose univentionstaff 2017-05-23 21:38:52 CEST
A new app has been published and i want to install it. So i start my UCS server, log into UMC and open the App Center. But the app is not displayed correctly.

I have to close and reopen the app center module before the app is displayed correctly.

Reproducer: My UCS 4.2e0; start UCS, open UMC App Center. Search owncloud: The owncloud 9.1 App is found. The new owncloud X App is only shown after i close and reopen the UMC App Center module.

One can see that an outdated cache is used, because the renamed 'owncloud 9.1' app was named 'owncloud' before...

Single Master Environment (Update is shown, but no update button)

A partner had a similar problem on several machines and I was able to reproduce this on his system: UCS 4.2-1e76 Single-Master (no other

An OX update was shown in the main screen, and the screenshot shown a new version for the app but there is no "update"-button. A second and a third browser with a completely new session does not show any change. The button is still missing.

If the appcenter module is closed and reopened (same UMC session!), the update button appears.

I'm not sure if customers will find this "solution"/"workaround" on their own, so I think we should fix this issue.

No new reports since 2017. Has this behaviour been observed lately?
