Related entities to a multi-valued related entity not indexed as a list.

Hi,

I have a simple compound-field with, for the sake of brevity, let's say two, fields: tid & amount. Tid is a term-ref, and amount is a integer. I then have a field which is a multi-valued field.

If you var_dump the relevant output from entity_get_property_info it's set as:

field_NN = array(
  label => 'NN',
  type => 'list<NN>',
  getter callback => 'entity_metadata_field_verbatim_get',
  field => TRUE,
  property info => array(
    amount => array(
      type => 'integer',
      label => 'Amount',
      getter callback => 'NN_entity_metadata_field_property_get'
    )
    tid => array(
      type => 'taxonomy_term'
      bundle => 'a_vocabulary',
      label => 'Term',
      getter callback => 'NN_entity_metadata_field_property_get',
      options list => 'entity_metadata_field_options_list'
    )
  )
)

If you then add the related entity 'NN' you get the field 'NN » Amount' added to your list of fields. And you can then choose to add 'NN » Term' as a related entity which will give you the term fields, amongst which is 'NN » Term » Name'.

After both 'NN » Amount' and 'NN » Term » Name' is added to the list of fields, I can var_dump the options['fields'] from the Index entity, and I get the following:

array(
  field_NN:amount = array(
    name => 'NN » Amount',
    type => 'list<integer>',
    boost => 1.0,
    indexed => 0,
  ),
  field_NN:tid:name = array(
    name => 'NN » Term » Name',
    type => 'string',
    boost => 1.0,
    indexed => 1,
  )
)

The fault here is that field_NN:tid:name has its type set to 'string', not 'list'. This is turn causes Search API Solr to choose the field-name ss_field_nn:tid:name. Then when indexing, this causes an indexing error!

So what I'm saying is: If you have a single-value related entity to a multi-valued related entity, it should be indexed as being multi-valued instead of single-valued as it currently is.

I haven't had time to figure out where the fault is - but I'll probably look into it next week if you want a patch.
