Excellent framework for showing a report based on a single query. Two items let it down for me: a) The comprehensive manual is not as good as it needs to be for developers to easily extend the type of reports available and b) the component can be called by a URL even when not logged on. Line 21 in rokreporter.php seems to be the problem.
Overall a very useful package which met nearly all of my needs, and is probably capable of doing all of them once I figure out the fine details of how it is all put together.
