Update children nodes with PowerShell doesn't reflect in SharePoint GUI - powershell

Question

I'm trying to update a node title on my SharePoint site with PowerShell:
$web = Get-SPWeb "http://dev:18792/sites/devsite/"
foreach ($webs in $web.Webs)
{
$nodes = $webs.Navigation.QuickLaunch
foreach ($node in $nodes)
{
$nodeTitle = $node.Title
if ($nodeTitle.ToString().Contains("First node"))
{
foreach ($nodeChild in $node.Children) {
$nodeChildTitle = $nodeChild.Title
if ($nodeChildTitle.ToString().Contains("Original childnode title")) {
$nodeChild.Title = "Changed title"
$nodeChild.Update()
Write-Host "done."
}
}
}
$webs.Dispose()
}
$web.Dispose()
}
If I try it a second time and change
.Contains("Original childnode title")
to:
.Contains("Changed title")
It does enter that if statement, but the changes is not visible in the GUI.
Am I missing something here?

Answer 1

Could it maybe be because you have the Publishing features activated? Manipulating the quick launch in a publishing site is a bit different. Here's some sample C# code:
PublishingWeb pubWeb = PublishingWeb.GetPublishingWeb(oWeb);
SPNavigationNodeCollection nodes = pubWeb.Navigation.CurrentNavigationNodes;
foreach (SPNavigationNode node in nodes)
{
if (node.Title == "Original Title")
{
node.Title = "New Title";
node.Update();
break;
}
}
Otherwise try calling the $webs.Update() method
