Rails - Jan 2006 - Limited eager loads and conditions on the eager tables

Hi,

Why are limited eager loads and conditions on the eager tables incompatible? 

Doing a find(:all) without :include causes a select * query to be generated, 
which means the id fields everwrite each other if associated tables are 
included using :joins.

But using :include, if conditions are placed on the tables listed in :joins 
then Rails throws an exception when :limit is included too.

Ordinarily I''d just leave out the limit, but I''m populating a
div of limited
size with draggables so I can''t have overflow set to auto, or they
can''t be
dragged out of the div...

Anyone have any suggestions as to how to use conditions on joined tables with 
limits as well? I''m thinking I might have to use :joins with :select
and name
the columns specifically, but it makes for messy code.

thanks,
mark
