Hi, at last i found the problem... 
I'm missing this config:

	<settings
		cacheModelsEnabled="true"
	/>

but i'm pretty sure the docs said that cacheModels are enabled by
default. 

Anyway.. thanks for the feedback,
Yusuf

Hi Larry,
fyi, i think the workaround is not working

tried this:
	sqlmap.queryForList("selectTest", "dummy");
combined with this
	<select id="selectTest" resultClass="map"
cacheModel="cache.references">

also tried this:
	sqlmap.queryForList("selectTest", "dummy");
combined with this
	<select id="selectTest" parameterClass="string"
resultClass="map" cacheModel="cache.references">

it still generate something like this in the log everytime i call it:

[DEBUG] [java.sql.Connection:42] - {conn-100009} Connection
[DEBUG] [java.sql.PreparedStatement:48] - {pstm-100010}
PreparedStatement:    select * from ... ...
[DEBUG] [java.sql.PreparedStatement:49] - {pstm-100010} Parameters: []
[DEBUG] [java.sql.PreparedStatement:50] - {pstm-100010} Types: []
[DEBUG] [java.sql.ResultSet:41] - {rset-100011} ResultSet
[DEBUG] [java.sql.ResultSet:61] - {rset-100011} Header: [a, b, c]
[DEBUG] [java.sql.ResultSet:65] - {rset-100011} Result: [a, b, c]

but i'm pretty sure some time ago (dont know the exact version, but an
older one) i successfully used the caching feature.. 

Thanks,
Yusuf.

Yeah...this is almost a bug, but not quite..the assumption is that if
you have no parameters that the query must change based on something
else, so it doesn't get cached. :-/

A workaround (I think..) is to call the query with a parameter object
that you ignore.

Object o = sqlmap.queryForList("ns.query", "ignoreMe");
