Hi guys,
I’m reading group members from an AD group into a variable and want to load them into a dynamic table and display them. This works so far, but the table always only shows maximum two users, even though there are more. If I output the variable with write-output, all the group members are there, but the table still only shows two. I just don’t understand why.
Product: PowerShell Universal
Version: 5.5.3
Show your code where you have the issue. It’s easier to help if we can see what you are trying to do.
I figured out where the problem lies.
The problem seems to be the array!
When I run the app for the first time and read a group that has 3 members, the table displays those 3 members. If I then read a group with fewer members, that’s no problem; they are also displayed. But if you then read a group with more than 3 members, a maximum of 3 members are displayed!
So the size of the table depends on the number of users to be displayed in the first run?! WTF!
So if I select a group that has, say, 50 members when I start the app for the first time, the table will only show a maximum of 50 results for subsequent queries

Nice work finding the issue. I would suggest you read up on the scope variables to understand why you $page:DSV var might contain “old” data from a previous run.
In this case you might need to close down your tab and open a new one to get fresh data.
Here is the direct link to your live documentation:
https://YOURURL/apps/docs/Scopes
Or in your admin dashboard, click on Apps → Apps → Live Documentation Button
Thanks for your reply. Yeah, i have to learn a lot of thinks because everything is new to me.
No, the variable doesn’t contain any “old” or “invalid” data.
When I output the variable to the log, it contains exactly the data that should be output. But this data isn’t displayed in the table.
I’ve also built in a small counter that counts the array. It also displays the correct number.
$length = $Page:DVS.length
Show-UDToast "$length" -BackgroundColor 'orange' -MessageSize '24' -Duration '5000' -CloseOnClick -Position 'center'
But for some reason, the table is somehow limited to the number of users who are read first.
So if the first group only has 2 members and I then select another group in the select box that has 4 members, only 2 members are displayed in the table - even though the variable/array contains all 4?!
I dont get it! Sitting here for days on such a simple task!
This is not how I imagined it with powershell universal… 
If I had to reload the page every time, why would I need a dynamic table? That would be completely insane.
I see what you mean. Using your code I am experiencing the same thing. If I have a 4 users group and change it to a different group with 10 users, It will only show 4 out of the 10 users in the table. So the first choice will always limit the number of rows visible in the table.

I’ve created a simple version here that does not need AD to run. It had the same problem, right until I moved the new the new-dynamic to include the New-UDselection. So that seems to have fixed the problem for me.
Try and move your new-uddynamic to include new-udselection and it should also fix your issue. Give it a shot and let me know the outcome.
