“Collection was modified; enumeration operation may not execute.”

New-UdColumn -Size 1.5 {
New-UDCard -Title "Automatic Services" -TextSize Medium -Endpoint {
							$SVCCT = (Get-Service -ComputerName $Session:CurrentServerIP | where {
									$_.StartType -eq "Automatic" -and $_.Status -eq "Stopped" }).count
	$SVCTXT = "$SVCCT Stopped Services"
	New-UDButton -Text $SVCTXT -Icon stop_circle -IconAlignment left -OnClick {
		Show-UDModal -Content {
									New-UdGrid -Title "Automatic And Stopped Services" -NoPaging -NoFilter -NoExport -Headers @(
										"Name", "Display Name", "Status") -Properties @("Name", "DisplayName", "Status") -Endpoint {
										Get-Service -ComputerName $Session:CurrentServerIP | where {
											$_.StartType -eq "Automatic" -and $_.Status -eq "Stopped"
										} | select "Name", "DisplayName", "Status" | Out-UDGridData
			}
		}
	}
}

Appreciate if any one can help, i am spinning around with no results.

Can you reload the page and then look in the log again? See if the error that you see on the screen is present in the log. If it is, I would need to see the stack trace for it. The stack trace shouldn’t include any sensitive info.

i think this should be the area o interest

Just having a real quick look your on 2.5.3 yeah? ANy chance you can upgrade to 2.6.0 and see if this is still present

9

will do that immediately

Worth a shot. This might be a bug in UD. I’m not exactly sure what’s going on but it looks like the endpoint registration may be throwing this exception. Nothing is standing out to me in the code but I’ll try and reproduce.

11

Awesome to see it’s not just me who codes at silly o’clock…so there is something in that endpoint it doesnt like on the button…any chance you can put that endpoint code for the button?

If you say this happens on refresh is there something in that endpoint that takes a good few seconds to initialize then the page is loading before the endpoint? I will try and replicate the problem if I can from code posted. Thanks

Sorry I just seen your code at the top of the page…Doh! Ok so sometimes I get a weird error if Im calling from SQL and the page loads before the data is displayed in the table, then a refresh sorts this out…so

12

tested with 2.6.0 the same issue is there ,
and yes all the code is based on SQL invoke-sqlcmd and get-wmi… as it should manage remote servers is there is any way to tell the page to wait for all endpoints

just a side note , i can’t now get the UDLogging working after the upgrade from 2.5.3 to 2.6.0 i am using
Enable-UDLogging -FilePath C:\temp\log.txt
the log file is not created but the previous version was working fine.

13

sorry forgot to say that the same issue is happening randomly even while loading from CSVs

14

I’m suspecting a problem with UD. Can you tell me about how many buttons you have on that page that are using onClick?

15

Hello Adam,

did you get any updates.

16

@alaaelmahdy,

I have tested your posted code and could not re produce the issue except i have made a huge improvements that makes your code run a lot faster which i believe it will fix your issue as well

here is an example using $cache

    Get-UDDashboard | Stop-UDDashboard

    $Schedule = New-UDEndpointSchedule -Every 1 -Minute

    $ServiceCount = New-UDEndpoint -Schedule $Schedule -Endpoint {

    $Cache:ServicesCount = (Get-Service -ComputerName $Session:CurrentServerIP | where {
    			$_.StartType -eq "Automatic" -and $_.Status -eq "Stopped" }).count

    $Cache:Services = Get-Service -ComputerName $Session:CurrentServerIP | where {
    			$_.StartType -eq "Automatic" -and $_.Status -eq "Stopped"
    			 } | select "Name", "DisplayName", "Status"
    }


    $Dashboard = New-UDDashboard -Title "Inputs" -Content {
    New-UdColumn -Size 1.5 {
    New-UDCard -Title "Automatic Services" -TextSize Medium -Endpoint {
    							
    	$SVCTXT = "$Cache:ServicesCount Stopped Services"
    	New-UDButton -Text $SVCTXT -Icon stop_circle -IconAlignment left -OnClick {
    		Show-UDModal -Content {
    	New-UdGrid -Title "Automatic And Stopped Services" -NoPaging -NoFilter -NoExport -Headers @(
       "Name", "Display Name", "Status") -Properties @("Name", "DisplayName", "Status") -Endpoint {
    	$Cache:Services | Out-UDGridData
    			     }
    		      }
    	       }
         }
     }
  }

     Start-UDDashboard -Dashboard $Dashboard -Endpoint @($ServiceCount) -Port 1000

in above example the page will load super fast and the services will be updated every 1 minute this way you are not calling get-service command more often.

also you can make it look little bit nicer like this

I’ve also found an issue with UD that might be causing the initial issue. It’ll be in tonight’s nightly release if you want to give it a shot.

18

Dear Wael,
Thank you for your suggestion will rewrite the code your way and give it a try.
Thanks
Alaa Elmahdy

It hasn’t been released to the gallery yet. You’ll need to install the nightly release: https://github.com/ironmansoftware/universal-dashboard/blob/master/tools/install-nightly.ps1
