Having this odd issue I can’t seem to understand with the new Criteria Builder.
When searching with offset=0 and max=10 (or max), it works fine. But once I ask for any higher offset, Criteria Builder throws an undefined the error “variables results is undefined”.
I copied my function and the stack trace to a gist; https://gist.github.com/a14d94685099203c06c3
While viewing, please note that the only arguments I’m passing to get this error are:
(and I leave these default values as defined in the arguments)
If anyone could point me to why this is happening, I would greatly appreciate it.
what kind of database type? Microsoft SQL Server? MySQL?
It’s MySQL, no query logging - I would have explored that if it hinted the root cause being a database issue, but it’s CB’s CriteriaBuilder.cfc #214 that’s throwing the error. Do you think it’s the query?
Yes, I would look at the logging of the SQL. My guess is that hibernate is returning a null value to results and you at trying to reference it. I’ve had this problem in the past with hibernate and my object being empty/null.
Are you using Railo or ACF?
I agree with Jeremy–turn on SQL logging in dev and leave it on. It is an invaluable help, not only for debugging errors, but also for understanding how CRiteriaBuilder and Hibernate turn your criteria queries into SQL.
Took a while to track it down, but I enabled the general query log and found it, formatted for readability but the query doesn’t error and returns the correct results:

(SELECT fn_projectpatterncount(this_.project_id)) as formula2741_0_
LIMIT 12, 12;
Just to eliminate issues, is it possible that your offset exceeds the number of records?
For more elimination, what if you turn off query caching?
I know this is going to sound odd, but I just found the reason.
If I call count(); after list(), it will error. But if I call count() before list(), it works fine.
I still suspect the reason is the count method of CriteriaBuilder.cfc, specifically lines 210-213 but I don’t know why.
Doesn’t sound odd at all. I ran into the same issue a while back (sorry I didn’t suggest that earlier, I’m doing this on my cracked, cramped mobile).
In my super search method, I had to order my list() and count() methods appropriately so as to avoid this.
Glad you got it working
I think the reason the count fails after the list() is because of the sortOrder being included. If you remove this, does the count work after list() ?
