Steve will have to help with that as I'm not familiar with that code.

You're right ! In fact, I think the problem is in cn1-data-lib-access. As
object array is construct, it can't receive NULL value since all object are
converted to String. For example, for insertion :
/**
* Gets generic insert args for insert statement for the given map of row
data.
*
* @param m
The main issue is old fallback code. The iOS implementation is native so
the sqlite layer has no notion of "object".
Notice that in the string conversion "null" is preserved as null so it
should work correctly:
if (params[i] == null) {
strParams[i] = null;
I come back to this topic which is very problematic for me. The manner
which I use permit me to read/save null values in database. But in fact,
it's "null" string values that are stored in db. So, there is no constraint
validation possible with that. Even worse, foreign key constraint can
faile
Hi,
FYI Shannah,
I modified DAO.java in your framework like :
/**
* Fills a map with the data of the current row of database Cursor
*
* @param c
*The database cursor from a query.
* @param m
*The map to fill.
* @throws IOException
*/
protected void fillMap(Cursor c, Map
Ok I've misunderstood !
Problem is I've no control on this code since it's included in shannah's
plugin (cn1-lib-access).
Whatever, I will bypass my problem differently.

What I was trying to say is this:
Use your number code as before without a problem. However, when you need to
check if a value is null use the getString() method to check that special
case.

Thanks for both your responses.
Sure I know I can save null values with custom queries. In fact, my code is
already adapted to invoke framework's method (eg : update/save/find), so I
don't use custom query (and prefer don't use it).
When I initialize my database, Integer/Long column contains NU
