Array attribute in af:region

[Arnaud MERGEY]

Hi,
Is it possible to define array attribute in region-metadata.xml ?

I'have tried this
<attribute>
           <attribute-name>objectInstances</attribute-name>
           <attribute-class>demo.MyType[]</attribute-class>
           <attribute-extension>
               <required>true</required>
           </attribute-extension>
       </attribute>

And I have java.lang.ClassNotFoundException: demo.MyType[]

thanks for help.
Arnaud
