XPath query issue when querying compounds, maybe permission related.

Description: this seems to have something to do with user rights. When querying compounds using XPath, liveuser doesn't get any results while admin got expected result set. There are no errors in the logs.

Reproduction path:

In the latest Go-Green: change the 'poll:introduction' of a 'poll:poll' compound so that it starts with 'A' for instance, and then query the repository as 'admin'and 'liveuser' using the repository servlet:

//element(*, poll:poll)[jcr:like(@poll:introduction, 'a%') or jcr:like(@poll:introduction, 'A%')]

liveuser: 0 results
admin: 1 result

Number of results found: -1

In the repository servlet, the liveuser can browse the polls, and can even see the poll:poll fields.
