LazyList and Collections.sort() and Collections.reverse() behavior

[helloariel]

Hi there,

I'm getting very inconsistent and buggy behavior when calling Collections.sort() and Collections.reverse() on the LazyLists returned by query.getResultList(). Basically, the lists are sometimes properly sorted and reversed and sometimes they are half sorted, not sorted in the right order, etc.

I couldn't narrow down the issue precisely but I assume it happens if the LazyList isn't fully populated. Couple questions:

• Is there anyway to force the lazylist to be populated, or disable lazy loading altogether?
• Is there any precautions I need to take for these lazy list to behave as normal lists?

Thanks!

Probably best to iterate through the results (LazyList) and add them to another collection that supports all those functions.

That's what I ended up doing. Iterating through the list and adding them to an ArrayList. The behavior of LazyList seems very dangerous however. Maybe it doesn't fully comply with the specifications of the List interface?
