Type formatting question on properties that are collections

OK I'm trying to figure out it is that some collections get expanded and some don't. I have a Send-SmtpMail cmdlet that spits out the MailMessage object and that it sends and the output needs a little work:

5> gps w* | Send-SmtpMail -to john@doe.com,jane@doe.com -Subject "Test" -Body "Hi" -AttachmentPath \temp\foo.* -whatif
What if: Performing operation "Send-SmtpMail" on Target "System.Net.Mail.MailMessage".

Now why does the Attachments collection (AttachmentsCollection) contents get displayed but the To collection (MailAddressCollection) contents don't get displayed?

Do the following:
5> $x = gps w* | Send-SmtpMail -to john@doe.com,jane@doe.com -Subject "Test" -Body "Hi" -AttachmentPath \temp\foo.* -whatif
What if: Performing operation "Send-SmtpMail" on Target "System.Net.Mail.MailMessage".
6> $x.To |Format-list *
7> $x | %{"$_"}

And send the results.

Here ya go:

2> $x.To | Format-List *


DisplayName :
User : john
Host : doe.com
Address : john@doe.com

DisplayName :
User : jane
Host : doe.com
Address : jane@doe.com



3> $x | %{"$_"}
System.Net.Mail.MailMessage
4> $x

Subject : Test
IsBodyHtml : False
Body : Hi

Hmm, perhaps the MailAddress object is using the DipslayName as its representation? How do I override that behavior for the display of a collection of those objects?

Sorry. Actually I meant to ask for
5> $x.To | %{"$_"}
(I'm thinking that they might have a broken ToString(). If you look at the $X , it actually is printing out a list of 2 items but each item appears to be a null string.

To : {, }

Hmm.. BTW I do have a custom formatter for MailMesage which is the object that contains the MailAddressCollection but I haven't defined anything for MailAddress. Here's the MailMessage view which is just hiding extraneous properties:

<View>
<Name>System.Net.Mail.MailMessage</Name>
<ViewSelectedBy>
<TypeName>System.Net.Mail.MailMessage</TypeName>
</ViewSelectedBy>
<ListControl>
<ListEntries>
<ListEntry>
<ListItems>
<ListItem>
<PropertyName>From</PropertyName>
</ListItem>
<ListItem>
<PropertyName>ReplyTo</PropertyName>
</ListItem>
<ListItem>
<PropertyName>To</PropertyName>
</ListItem>
<ListItem>
<PropertyName>CC</PropertyName>
</ListItem>
<ListItem>
<PropertyName>Bcc</PropertyName>
</ListItem>
<ListItem>
<PropertyName>Attachments</PropertyName>
</ListItem>
<ListItem>
<PropertyName>Priority</PropertyName>
</ListItem>
<ListItem>
<PropertyName>Subject</PropertyName>
</ListItem>
<ListItem>
<PropertyName>IsBodyHtml</PropertyName>
</ListItem>
<ListItem>
<PropertyName>Body</PropertyName>
</ListItem>
</ListItems>
</ListEntry>
</ListEntries>
</ListControl>
</View>

BTW I still don't see the To entries when I remove this view definition so I don't think this view definition is causing the problem.

F.Y.I., same happens on a dataSet ( I noticed on my new Tabcompletion script)

PoSH>$dsTabExpansion

DefaultViewManager : {System.Data.DataViewManagerListItemTypeDescriptor}
EnforceConstraints : True

Sounds like it is time to file a bug.
