Possible issue with LAZY Loading

Hi, We need lazy loading for one of our large data sets. When I run currently against both 2.4.2 and 2.4.3_01 the db is always returning everything, including the data marked as Fetch.LAZY.  I wrote the attached unit test, and then found this: http://www.objectdb.com/database/forum/9 As far as I can tell, my unit test is pretty much identical.

Explorer in 2.3

First, the new Explorer in ObjectDB is fantastic! This is exactly what we've needed - an easy way to do ad-hoc JPQL queries and navigate through the results and even make small changes to primitive data and Strings. After playing with it for a while, here is a list of additional features I'd love to have: 1. Export of selected data: a. Simple - Select a range of cells or a column header and copy text to the clipboard or save to a file (csv, html, etc..).
