client code supercolumn insertion from cassandra 0.3.0 to 0.4.0

[ROGER PUIG GANZA]

Hi, I'm having problems with the translation of the client code for Cassandra 
0.3.0 to the 0.4.0
My code for inserting columns is working properly but the one for the 
supercolumns is not working.
Can anyone point me where the error is?

I'm skipping the exception handling code.

Code for Cassandra 0.3.0  is working properly, I can get the values with the 
client code using the get_superColumn method and throught Cassandra-cli using 
get <tablename>.<CFName>[<key>][<col>][<subcol>]

Map<String, List<superColumn_t>> sColMap = new 
HashMap<String,List<superColumn_t>>();;
Map<String,List<column_t>> colMap = new HashMap<String,List<column_t>>();;
List<superColumn_t> sCol = new ArrayList<superColumn_t>();;
List<column_t> columns= new ArrayList<column_t>();

columns.add(new column_t(subColKey, "".getBytes("UTF-8"), timestamp));

sCol.add(new superColumn_t(columnName, columns));

sColMap.put(superColumnName, sCol);

batch_mutation_super_t bms = new batch_mutation_super_t(keyspace, superColKey, 
sColMap);

client.batch_insert_superColumn(bms, false);


Code for Cassandra 0.4.0 . It's suppoded to be working but when I fetch a 
superColumn with using the superKey, it returns a NotFoundException and when 
using the Cassandra-cli, I get this
InvalidRequestException(why:column parameter is not optional for super CF 
<CFName>

List<Column> colums = new ArrayList<Column>();
Map<String,List<ColumnOrSuperColumn>> map = new HashMap<String, 
List<ColumnOrSuperColumn>>();
List<ColumnOrSuperColumn> subColumns = new ArrayList<ColumnOrSuperColumn>();

columns.add(new Column(key.getBytes("UTF-8"), "".getBytes("UTF-8"), timestamp));
subColumns.add(new ColumnOrSuperColumn(null, new 
SuperColumn(InfoPerUserColNames.CFDevel.getBytes("UTF-8"), columns)));

map.put(superColumnName, subColumns);
client.batch_insert(keyspace, superKey, map, ConsistencyLevel.ZERO);


thanks for your help.
