copyField chain

Question

I tried to use copyField like a chain but it doesn't seems to work. Here my example:

<copyField source="allfields" dest="metafields1" />
<copyField source="metafields1" dest="metafields2" />
<copyField source="metafields2" dest="metafields3" />

Each field uses a different fieldType.

The problem is that except of allfields and metafields1 the other have no content after indexing. Is solr unable to copy from another copyField? I use solr 3.5.

Documentation @ http://wiki.apache.org/solr/SchemaXml#Copy_Fields

The copy is done at the stream source level and no copy feeds into another copy.

Having a copyfield as the source of copyfield tag does not work.
The copyfield source must be an actual field, which has some value and does no cascade.
