Problems inserting in sqlite and hxcpp

[Serjor]

Hello,

I'm trying to insert a field in a sqlite db, but I'm getting "null object reference" error :-(

I've been googling, and if I'm not missing something very obvious, my code is pretty close to the samples I've found.

This is the code:

package  ;

import sys.db.Connection;
import sys.db.Object;
import sys.db.Sqlite;
import sys.db.Manager;
import sys.db.TableCreate;
import sys.db.Types.SId;
import sys.db.Types;
import sys.FileSystem;
import sys.io.File;
import sys.io.FileInput;

class TMC extends Object
{
    public var Id:SId;
    public var Path:SString<255>;
    public var Confemi:SInt;
    public var Serial:SString<8>;
    public var Transceiver1:SInt;
    public var Transceiver2:SInt;
}
 
class TmcScanner
{
    public function new()
    {
        var cnx = Sqlite.open("tmcscanner.db");
        Manager.cnx = cnx;
        Manager.initialize();
       
        if (!TableCreate.exists(TMC.manager)) {
            TableCreate.create(TMC.manager);
        }

        var tmc = new TMC();
        tmc.Confemi = 10;
        tmc.Serial = "";
        tmc.Path = "/a/path";
        tmc.Transceiver1 = 5;
        tmc.Transceiver2 = 0;
        tmc.insert();
       
        Manager.cleanup();
        cnx.close();
    }
}

Any idea?


Thank you

Does the TMC class have

public static var manager = new Manager(TMC);

Or something similar?  That could be your null error perhaps...

Thank you for your answer, but I didn't use it, because the documentation I've found says that is not necessary.
But I've tried your suggestion and I'm afraid that nothing changes.
I've also tried "public static var manager = new Manager<TMC>(TMC); ", but error persists.

If you compile with -debug, you should at least find out which object is null.

According to vs2010 debugger, tmc->mPtr->manager is ok, but tmc->mPtr->sys::db::Object_obj->_manager is null.
How can I initialize it?

Thank you
