Search Function for Collection - Map

[GoogleCodeExporter]

Quick question: does the framework support search function on Map type 
property, for example, we have an entity A which has a property Map<String, 
String> m, then I want to filter A base on the key of the map m, is there a way 
to do it, I tried m.key, but it didn't work. I searched the posts here, and it 
says "Filtering on collection properties with SOME, ALL, and NONE is 
implemented in 0.4.2.", but are they only for List type?

If I post this in the wrong place, please correct me, I haven't found any other 
place to post question, sorry in advance.

By the way, it is an awesome framework, especially the search function, one of 
my favorite frameworks now.

Thank you very much.

No I don't think think the framework supports this yet. HQL does apparently 
support it as follows:

"You can use HQL built-in function: index() eg.

select item, index(item) from Order order 
join order.items item
where index(item) = 'foobar'

where order.items is Map"
-- http://forum.springsource.org/archive/index.php/t-32224.html

By the way, the best place to post questions is here: 
http://groups.google.com/group/java-generic-dao. That's the discussion group 
for the framework. But I'll leave this here since it's a good feature 
suggestion.

Developer note:

Use ".index" just like ".size". But maybe both of these need to be adjusted so 
they don't step on legitimate properties "index" and "size".

works.
