This should be in
the docs. I wasn't sure if it was supported, so I tried it and it worked.
Because it's not obvious that multiple groupBy attributes will work, it should
be documented.

Subject: Re: Multiple JoinsThis really isn't that difficult. Join your three tables in the query, then do a groupBy on the nested result maps. Have you tried it?<resultMap id="t1" class="T1Class" groupBy="t1key">...<result column="t2Objects" resultMap="t2"/></resultMap><resultMap id="t2" class="T2Class" groupBy="t2key">...<result column="t3Objects" resultMap="t3"/></resultMap>
<resultMap id="t3" class="T3Class">
...</resultMap>You can carry this on for as many tables as you need.

Hi Larry;
I see already this example it shows a simple example with only one join but
a multiple Joins (with for example 3 tables : T1 => 1..* T2 => 1..*T3).
