Another custom type handler issue

[Ken Katsma <ke...@gmail.com>]

Now that I have the custom type handler executing correctly for the nested 
cursor, I have another question :)

I'm trying to use the custom type handler to populate an array of objects in 
my class. For instance, I have a Client, which contains Address[] arrays and 
Communication[] arrays. I'd like to populate it with a custom type handler. 
While I can get the type handler to execute for a single Address or 
communication object, I can't seem to find a way to get iBatis to understand 
that it needs to fire a type handler for an array of those objects.

An even better way to handle this would be if there were some way I could 
nest the result maps so that I point the nested cursor to a second result 
map.

Any ideas?

Either way, I think I feel another hack coming on :(

Thanks,

Ken

I would like to see an example of how the list approach might work (when 
using a nested resultset).  In the case of the array, I found the 
solution.  You just have to define the array in the custom type handler 
using the format [Lpackage.ClassName; and it will fire the custom type 
handler.  I then am using the type handler to iterate over the nested 
resultset.

If there is a way to do this using nested resultmaps it would be great, 
but I haven't seen an example.

Thanks,

Ken

Do you have to use arrays? How about lists instead? iBATIS (to my
knowledge) doesn't support returning arrays. My guess is if you were
to have List<Address> addresses and List<Communication> communications
(type specification not necessary, just highlighting what its doing) -
then iBATIS would "do the right thing".
