bug with Get-CDDrive

[halr9000]

I forget if I raised this before but I hit it again today so to be sure, here it is...I'm not sure how to explain this, so I'll just show it:

PS > (Get-VM vcenter* | Get-CDDrive).connectionstate

           AllowGuestControl                    Connected              StartConnected
           -----------------                    ---------              --------------
                        True                        False                       False


PS > Get-VM vcenter* | Get-CDDrive | select -expandProperty connectionstate
Select-Object : Cannot expand property "connectionstate" because it has nothing to ex
pand.
At line:1 char:39
+ Get-VM vcenter* | Get-CDDrive | select  <<<< -expandProperty connectionstate

This technique works with every other object on the planet aside from CDDriveImpl.

I seem to have this problem with -expandProperty globally.

See for example

Thanks for posting that link, I knew we'd had this discussion before but I couldn't find it. But regardless, we haven't yet heard from VMware...

Here's an example of this working with another object

§ ATLLAPHROTTENBE {~} Get-VM | select -expandProperty cddrives -first 2


IsoPath         : [SAN_VOL1] images/SLES-10-i386-GMC.iso
HostDevice      :
RemoteDevice    :
ConnectionState : VMware.VimAutomation.Client20.ConnectInfoImpl
Id              : VirtualMachine-vm-385/3002
Name            : CD/DVD Drive 1

IsoPath         :
HostDevice      :
RemoteDevice    :
ConnectionState : VMware.VimAutomation.Client20.ConnectInfoImpl
Id              : VirtualMachine-vm-463/3002
Name            : CD/DVD Drive 1

Hi all,

10x for the info. I'll log this in the bugtracking system so it get investigated. Once we isolate the problem I'll try to make a list with all VIToolkit objects that this does not work for.

Hi,

We did a litle research and this seems like a Powershell problem, which is resolved in Powershell 2. For example the problem with expanding the connection state of the cddrive object is not present when I tried to duplicate it it with Ps2. Something else, if you try:

$files = ls *.dll

$files[0] | select -expandproperty Directory, where the type of the Directory property is DirectoryInfo gives the same error with Ps1 and no error with Ps2.

Hope this will help.
