Setting empty multiple value field

[Geert Vanheusden]

Dear,

In Alfresco I have the following field:

<property name="foo:test">
        <type>d:noderef</type>
        <multiple>true</multiple>
</property>

If I try to set the properties but leave this field empty (not setting it), I 
get the following exception in OpenCMIS. 

Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
        at java.util.ArrayList.RangeCheck(ArrayList.java:546)
        at java.util.ArrayList.get(ArrayList.java:321)
        at 
org.apache.chemistry.opencmis.client.runtime.repository.PersistentObjectFactoryImpl.convertProperties(PersistentObjectFactoryImpl.java:463)

I tried to pass an empty List or a list with a null value but they all fail 
with one of the following exceptions:
* Property 'foo:test' is an Id property!
* Property 'foo:test' contains null values!

Any idea how I can set an empty value for a multiple value field?

Kind regards,

Geert Vanheusden
