IDM 3.5, Peoplesoft 5 driver

The driver is working on every attribute and synch's every attribute until
I want to synch a multi-value attribute. The attribute coming from
Peoplesoft is MAILALTERNATEADDRESS and the edirectory attribute is NSCP:
AmailAlternateAddress. The customer wants to use this field to hold an
email address in case the user get's married and they are assigned 2 email
addresses.

The error in the IDM log from the PS driver is:
<nds dtdversion="2.0">
<output>
<status level="error" type="driver-general">
<description>Publisher query exception:
com.novell.nds.dirxml.driver.psoftshim.CIException : Field '' does not
exist in schema 'MAILALTERNATEADDRESS'</description>
</status>
</output>
</nds>


The schema is mapped correctly and the filter is also. The attribute from
PS is being populated.

Here is the log showing the data:
<modify-attr attr-name="MAILALTERNATEADDRESS">
<add-value>
<value>
<component
name="MAILALTERNATEADDRESS">test.single@nospam.net </component>
</value>
</add-value>
<add-value>
<value>
<component
name="MAILALTERNATEADDRESS">test.married@nospam.ne t</component>
</value>
</add-value>
</modify-attr>

So I'm not exactly sure what that error means and how to fix it. Any help
would be appreciated.
