Søren Granfeldt PowerShell MA Export

Question

Hello everyone!
I have the following strange behavior with Søren Granfeldt PowerShell MA on Export:
I am using CSEntryChange objects on Export, so i want to determine only changed values in multivalue attributes.
Here is the example of export:
To display changed values in debug file i am using following powershell code:
    $atrChng = $_.ChangedAttributeNames
    foreach ($can in $atrChng)
        "Name: $can" | Out-File $DebugFile -Append
        foreach ($ValueChange in $_.AttributeChanges[$can].ValueChanges)
             $val = $ValueChange.Value
             $valmodt = $ValueChange.ModificationType
             "Value: $val $valmodt " | Out-File $DebugFile -Append
In my debug file i have the following result:
Name: members
Value: u6000041 Add 
Value: u6000042 Add 
Value: u6000048 Add 
This means that all attributes, even those that not have been changed are display as added attributes.
I have an idea that this behavior is because of Object Replacement type export of this MA. If i am right, does this mean, that there are no ways for me to get only changed values instead of sort out all of them? In my case i should exactly know
changed values to execute the target system API functions AddUserToGroup() or DeleteUserFromGroup() for each.
The other option is that i am doing something wrong :)
Thanks in advance for any help!

It is configured to do object replacement currently. However, if you - as it looks like you done - deselect the "Export Simple Objects" on the MA, you should be able to get the the AttributeChanges property on the exported CSEntryChange object
- and go from there using the MSDN documentation for this type of object (http://msdn.microsoft.com/en-us/library/microsoft.metadirectoryservices.csentrychange(v=vs.100).aspx).
Remeber that the AttributeChanges consists of a list objects of type AttributeChange, which again have some properties (i.e. ValueChanges) that you may want to examine (http://msdn.microsoft.com/en-us/library/microsoft.metadirectoryservices.attributechange_properties(v=vs.100).aspx)
You have to dig deeeeep...deeper that what you're doing with your current script. I have yet to go there...
