I want to be able to update the "JSLink" property on all views in two different lists. However I keep getting the following error:
"Collection was modified; enumeration operation may not execute."
I have the following PowerShell:
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue
#Temp Site
$siteColl = "mysitecollectionURL"
$site = Get-SPSite $siteColl
#JS file to add
$jSFile = "clienttemplates.js"
#Lists to update
$masterTasks = "Master Tasks"
$allTasks = "All Tasks"
Write-Host "`nChecking site:" $site.RootWeb.URL
#Get root web
$web = $site.RootWeb
#Iterating lists
foreach($list in $web.Lists)
{
if($list.Title -eq $masterTasks)
{
write-host "`n`tMaster Tasks list found"
#Iterating views
foreach($view in $list.Views)
{
$view.JSLink = $jSFile
$view.Update()
}
}
if($list.Title -eq $allTasks)
{
write-host "`n`tAll Tasks list found"
#Iterating views
foreach($view in $list.Views)
{
$view.JSLink = $jSFile
$view.Update()
}
}
}
$web.Dispose()
Write-Host "`n"
Where am I going wrong? Any suggestions would be much appreciated..
Use for loop instead of foreach, as inside foreach loop, it's not available to delete or update property:
$web = $site.RootWeb
For($i=0; $i -lt $web.Lists.count; $i++)
{
if($web.Lists[$i].Title -eq $masterTasks)
{
write-host "`n`tMaster Tasks list found"
For($j=0; $j -lt $list.Views.Count; $j++)
{
$view=$list.Views[$j]
$view.JSLink = $jSFile
$view.Update()
}
}
if($web.Lists[$i].Title -eq $allTasks)
{
write-host "`n`tAll Tasks list found"
#Iterating views
For($k=0; $k -lt $list.Views.Count; $k++)
{
$otherview= $list.Views[$k]
$otherview.JSLink = $jSFile
$otherview.Update()
}
}
}
$web.Dispose()
Here is a blog specify the same error message with the solution, please refer:
