DataSet does not refresh

[Gustel]

Hi,

we have the follwoing problem:

We retrieve images from webcams via DataSet. This worked for years, but since V 2.2.3 and V2.3.0 the refresh function gets stuck / sleeps. If we set the caching in the Layout to 0 it works. But our standard is 30 (minutes) and after a few intervalls it will stuck.

Regards

Hi, I can confrm this is a problem. I testet this issue last evening.

If I enter 0 as caching, it works! If I change the time value to something different, 5, 10 or 30, it refreshes 2 or 3 times and then freezes. Even a reboot of the CMS-VM does not work. Only setting the cache value to 0 triggers a refresh.

Maybe you can look into tis problem. We saw this problem the first time with V2.2.3 and is now with 2.3.0.

Thanks and regards

That is strange - just to confirm, the caching in the Layout means that you’re setting the cache settings on the Widget that uses the Remote DataSet?

Is that Layout definitely “active” i.e. being shown on a Player which is connected and requesting updates? We only update the Remote DataSets which are active on Players.

Given you’re a power user, i’m guessing all of the above is set up correctly. So would you be able give us a log of it not working? You can enable logging, and then set the “Fetch Remote DataSets” to “Run Now” and then capture the logs or a report fault zip file.

Hello Dan,

I have sent you the file via PM.

Thanks

Thanks for the logs - I’ve spent some time trawling through them and I can’t see any requests for your DataSet Ticker from the CONSOLE or XMDS log channels - only the WEB one (which is in the Layout Designer).

This suggests that the Widget wasn’t requested from XMDS inside the log window and therefore wasn’t in the required files set and wouldn’t have been kept up to date.

If you published the Layout after editing the cache period, then it might have taken a whole collection interval for the Player to request that file - so perhaps you didn’t log for long enough?

If we’re able to have an export of the Layout I can certainly try it here?

Hi Dan, I will send you the layout via PM this evening.

Thanks
