loading multiple map schema

$cat a.out
[key1#val1,key2#val2]*[key3#[val31,val32]]

grunt> a = load 'a.out' using PigStorage('*') AS (A:[], B:[]);
grunt> dump a;

here is the output :
([key2#val2,key1#val1],)

I guess it is not taking the second map, where the value is not a single
string but a list of strings. Any idea how to load this data type  ?

-Thanks,

What version of pig are you using ?

It works for me with 0.7 version and svn trunk version (local mode).

grunt> dump a;
([key2#val2,key1#val1],[key3#[val31,val32]])
