$srcObj or $dstObj returns single value instead of a expected multi value when querying multi value attributes (4286850)

For example:

userProxyAddresses = $srcObj["proxyAddresses"]

Although proxyAddresses is a multi-valued attribute, the userProxyAddresses variable will be assigned only one value.

This is by design. The $srcObj and $dstObj objects are designed specifically to query for/return single values.

WORKAROUND 1

Use the $commonParameters object to return all values of a multi-valued attribute.
Instead of $srcOjb use $commonParameters.CommonVars.SourceObject.Attributes["attribute"].Values
Instead of $dstOjb use $commonParameters.CommonVars.TargetObject.Attributes["attribute"].Values

The following sample script captures all of the values stored in the proxyAddresses attribute and writes them to a log file:

$logfile = "C:\Temp\QC-proxyAddresses_Debug.txt"
$message = "proxyAddress processing started for " + $srcObj["mail"]
Add-Content $logfile $message

$strValue = $commonParameters.CommonVars.SourceObject.Attributes["proxyAddresses"].Values

$message = "proxyAddress value in sourceObject is: " + $strValue
Add-Content $logfile $message
$index = 0
foreach ($Address in $strValue)
{
$message = " value " + $index + ": " + $Address
Add-Content $logfile $message
$index++

$return = $return + $Address + "||"
}

$return = $return.TrimEnd("||")
$return

WORKAROUND 2

In a related issue, values in a CSV file may be mistakenly split into multiple elements if the value contains commas.

For example, a "Job Title" may contain a value of "Associate, Sales Department". $srcObj["Job Title"] may return a value of "Associate" or " Sales Department"

The workaround for this is to use the $commonParameters object to return the split values and then join them using a comma.

$strValue = $commonParameters.CommonVars.SourceObject.Attributes["Job Title"].Values
$joinedStr = $strValue  -join ","
return $joinedStr
