Unexpected error $instance.psobject.members.Add($member)

This code creates a synthetic object.

$instance = new-object Management.Automation.PSObject
Add-Member -InputObject $instance NoteProperty 'Type' $type
write-host "Instance created - $type"
$instance.psobject.members|write-host
foreach ($member in $members)
{ Write-Host "Adding member '$($member.name)'"
$instance.psobject.members.Add($member)
}

As you can see in the output below, all the members
are added except the 'ToString' psScriptMethod.
But I get no error if I add this very same method to
this very same object, using exactly the same syntax,
at the command prompt.
Can anyone give me a hint why?

Instance created - PFW_FileID
System.String Type=PFW_FileID
System.String ToString()
System.Type GetType()
System.Boolean Equals(Object obj)
System.Int32 GetHashCode()Adding member 'LName'
Adding member 'EventNumber'
Adding member 'ToString'
Exception calling "Add" with "1" argument(s): "A PSProperty or
PSMethod object cannot be added to this collection."

Adding member 'Match'

Never mind.

I was caching the ScriptMethods like this.
Obviously there would be a native Method called ToString
so my synthetic member was never being created. The native
method really was a duplicate and thus the error.

if ($class.$name -eq $null) {
Add-Member -InputObject $class ScriptMethod $name $script}
$class.$name

Are you able to provide us with all of the code? We don't see how $type
and $members are defined, for example.
