Before I start pasting supporting data, is there a third typical cause of theme('pager') not returning anything?
I look at cause #1 being the element being the same as another (there are 3 on the page, and I gave them element ids of 2,3 and 4), and #2 being the SQL in the pager query not being uppercase (it is).
The query returns a record set, the parameters all look fine to me, and are the same as on other pages I have diff'd with, I believe. There is no pager in the page source, so it's not simply being hidden by some evil CSS.
This page is different than those where the pager appears in that it has 3 blocks each with a pager, each with a different element id, none of which appear.
