问题
I was wondering how to get this to run. In my application I have a Category table and Product table. I need to have a pager which combines both Categories and Products for display in one list (first categories then products). Is there a way to get this going ? I tried left joining in the pager's query, but doesn't seem to do the trick.

If you can write a doctrine query to return the complete list of what you want, then the pager will page it.
Not sure without a schema how you might write such a query, not even 100% sure what you want to do. But if you are trying to list products with related category info, then you'll be needing a join, else if you want a mixed list of categories and products, you'll probably be wanting a UNION query.
If you post a schema and a bit more info about what you are doing, can try to help you.

What i did to solve this was to write my own pager which extended the sfDoctrinePager and the created methods which give results in an array from 2 queries. Had to do some extra writting but worked fine.
