RE: Populating existing beans...

Thanks for the reply.
 I'm well aware of queryForMap, but the problem isn't grouping the objects.
 
Basically, I have a bean "graph" (or tree, or whatever) that has been constructed before there is enough information to run the final query. Also, I don't know the bean class before hand (and don't want to add it explicitly to the resultMap or resultClass argument)
 
As an alternative solution to my problem, if there was a way to do a queryForList, but specify the result class at runtime, that would be extremely helpful.

Daniel, there is queryForMap functionality in iBatis.  It looks like this: SqlMapExecutor.queryForMap(statementName, parameterObject, key).  The key will be a column in your result map which could be your bean.id property after the result map populates the bean.  I am not sure what you mean by populating existing beans, but I hope this helps.

MyBean is the base class, there are many types of "MyBean" objects.

Is there a away to tell iBATIS to use the bean in "byId" map as the
result object? Or do I have to get the result, and copy the values over
myself?

I know it can be done with queryForObject(String, Object, Object); but I
need it for something like queryForList or queryForMap

Thanks,
Daniel.
