Hello,
could it be that on global account orderLabel will be overwritten by orderId? When submitting order I used label "EUUS_Neo_1375740000513" (here the some name and time of machine in millis as label).
Later I realized that label of the order was changed to its orderId.
Making it more clear:
Following code on method

public void onTick(Instrument instrument, ITick tick) throws JFException {
    
        for (IOrder order : engine.getOrders(instrument))
        {
            if ( order.getState() == IOrder.State.FILLED  )
            {       
                console.getOut().println("Order is "+order.getOrderCommand()+", Time:" + dateFormatMR.format(order.getFillTime())+",   amount="+order.getAmount()+", 
Price="+order.getOpenPrice()+", StopLossPrice="+ order.getStopLossPrice()+", TakeProfitPrice="+ order.getTakeProfitPrice()+ " getId="+order.getId() + " getLabel=" + order.getLabel());        
    }

gives:

Order is BUY, Time:05.08.2013 22:00:01, amount=0.200122, Price=1.32622, StopLossPrice=0.0, TakeProfitPrice=0.0 getId=26614EUR/USD getLabel=26614EUR/USD

Could you clarify it, please?

On global accounts labels get used only before order fill. On global accounts orders on fill get merged to the instrument's position, which has only id and no label.

thank you for clarifying it!
What happens if I open a second order in the same direction as already opened first one. Will I have 2 different orderId's?

There is always one position per instrument. A newly filled order does not change the id of the existing position. You can also make sure of it by carrying out manual trading tests.
