[TYPO3-Solr] Indexing attachments from tt_news records

[Florian Seirer]

We are using solr (3.0.1), solrfal (2.0.2-dev, EAP) and tika (2.0.0-dev, EAP) to index pages, files and tt_news records.
Everything works so far, except for indexing of tt_news attachments. 

plugin.tx_solr.index.queue.tt_news.attachments.fields = news_files is set, but files from tt_news records still don't appear in the solr index.

These are the changes I made to the default TS from solrfalso far:

plugin.tx_solr.index.enableFileIndexing.recordContext = 1
plugin.tx_solr.index.queue.tt_news.attachments = 1
plugin.tx_solr.index.queue.tt_news.attachments.fields = news_files
plugin.tx_solr.index.queue._FILES.recordContext.tt_news = fieldConfiguration
plugin.tx_solr.index.queue._FILES.recordContext.tt_news.__recordContext.fileReferenceUrl < plugin.tx_solr.index.queue.tt_news.url
plugin.tx_solr.index.queue._FILES.recordContext.tt_news.__recordContext.fileReferenceTitle < plugin.tx_solr.index.queue.tt_news.title

Any idea what's missing/wrong?
