Hi Antti.

package install version 20.1. Browser newest Chrome.

Which versions exactly?

How do I report a problem/error correctly?

You must remember that the versions are constantly changing. And no one knows in 4 weeks which version you had at that time.

Without that, it is often difficult to reproduce the problem.

after a while i cannot change applications from clicking the menu.

Can you please explain this in more detail?

Does nothing happen when clicking, are the entries for other modules missing, or …?

Version is egroupware-docker (20.1.20201217) and all settings are default.
When i open the whole application changing between apps through menu works fine, but after not using the application for maybe a minute or so when i try to change the app by clicking app in the menu it gives the error which is shown in the picture i provided and in the error text in the first post. It doesnt matter which app/module i try to change, everytime it gives the same error and nothing happens.

Browser is mobile Chrome 87.0.4280.101

Update: When using mobile UI and quickly changing app, i get the error and nothing happens.

Hi Antti.

I have tried to reproduce your problem several times in the last few days.
I tested with a Chrome 87.0.4280.141, Android 9.1, EGw 20.1.20201217

I can only notice that I can’t scroll down, for example, if I have a very long list of favourites that goes beyond the screen at the bottom.
But that’s not what you mean, is it?

cannot change applications from clicking the menu

Does nothing happen when you tap a symbol or are the symbols not present at all?
I don’t quite understand your problem yet…

I’ll ask our developers about the error. But usually it is necessary for them to be able to reproduce it. Let’s see.

Hi Stefan and thanks for help!

I mean for example if i open the menu(picture above) and click for a while different symbols/apps for while app changes in the background but after a while i got the error messages and after that if i click symbol/app it just gives new/same error and the app doesnt change in the background.

Actually i was able to get it to work with commenting line from the code which is shown in the picture. Hopefully i didnt brake anything else

Thanks for recording the error & trace. It would have been impossible without that.
This is indeed quite difficult to reproduce and requires a specific sequence of events that I was not able to duplicate.
However, I believe I have fixed the issue and that fix will be in the next release.

(For posterity, it needs a pushed EDIT update from an app that has been opened but is not currently active, then you need to switch back to that app.)

You won’t lose any data, but you’re missing out on the latest changes from the server. You’ll want to just return or you will get other errors:

if (!this.div.is(':visible'))	// run refresh, once we become visible again
{
	return;// this._queue_refresh(_row_ids, _type);
}	

Thanks,
Nathan
