Sometimes a view does not load its data

Hello everyone,

In our application on a specific screen we have a view which is not responding with data at times. When we create a project in our application, we have a screen which displays some basic data, but this data is over the entire project and over different tables. To create four columns with the right data, we use a few “union all” statements.

The union all statements make sure four relatively complex queries are executed to create the following view:
 

This view sometimes fails to show its data, these columns are created by four queries on the respective tables and four times a union all. On the role where it goes wrong, only one of these columns is allowed to be shown, so could it be something like that, why it occasionally fails to load? Or is it because sometimes the query is too much for Indicium in combination with Azure to handle?

Does someone else have an occasionally failing screen on a query that is known to be quite slow at times? Because this happens, but when we do a quick refresh, all is well. This refreshing is relatively user unfriendly, so I hope someone can help to resolve this, whether its the query or something in Universal we may have configured incorrectly.

We experience the same behaviour with a view (GUI 2025.3.10 running on IIS). Our view is always used as a detail. Sometimes (but not always) when we open the detail for the first time, the GUI stays in an infinite loading state without showing the data (screenshot below). Only after manually refreshing or switching tabs, the data is loaded and it keeps working for different rows. Our view performs fine, it does contain a ‘union all’ as well though, however I am not sure if that is related to the issue. Reproduction is really difficult for this one.

I reported it in TCP (11092S) but it got closed because I was unable to respond in time. The ticket was reported with GUI 2024.3.15.0 which didn’t even load the action bar and grid headers (the screen was completely white).

 

Not sure if it is related or not, but I have a different TCP ticket (13517S, status on the backlog) that describes a reproducible issue of the combination of a ‘go to first row process action’ and a reference without columns that also causes an infinite loading screen (but with this issue it did show the data, it just disabled all buttons in the action bar). Workaround was adding an expression field for the reference.

What do you mean by “not responding with data”? Does the loading icon keep spinning, does the code fail. Or is the loading finished but no data is shown?

For me the loading icon keeps spinning.
