Jaka Jaksic commented on JCR-247:
---------------------------------
This is a killer feature alright, but it does not yet work as expected. Namely,
full-text search within linked files doesn't seem to work.
Take the following query for example:
"//element(*, nt:linkedFile)[jcr:deref(@jcr:content, '*')/jcr:contains(.,
'search string')]"
(should return all linked file nodes whose referenced resources contain the
given search string)
Running this query, an ArrayStoreException occurs in PathQueryNode, line 77:
return (LocationStepQueryNode[]) operands.toArray(new
LocationStepQueryNode[operands.size()]);
The problem is that the query operands are copied into an array of
LocationStepQueryNode, while the last operand is not of that type - it is of
type TextsearchQueryNode, which only extends QueryNode.
I have no idea how complex it would be to fix this. If it would require a lot
of work, then maybe for now just add some operand type checking and throw a
descriptive exception if an incompatible query node is found.
