Hello,

I have a batch class which is scheduled to be run at a particular time.

There is a bellow following piece of code inside:

  while (qr.next())
    {
        salesTable = qr.get(tableNum(SalesTable));

        setPrefix(salesTable.SalesId);

        if (this.process_check(onlyCustStorageFactor))
        {
            salesResrveForMultiThread = new SalesResrveForMultiThread();
            salesResrveForMultiThread.parmsalestable(salesTable);
            salesResrveForMultiThread.pack();
            this.batchHeader().addRuntimeTask(salesResrveForMultiThread, this.parmCurrentBatch().RecId, BatchConstraintType::And);
            salesResrveForMultiThread = null;

            //salesResrveForMultiThread.run();
            i  ;

        }
        n  ;
    }

Parameter salestbale isn't passed to the class SalesReserveForMultiThread. It gets null value and then gives me an error of course.

When I launch it manually and do not create runtimetasks parameter is passed correctly like that:

  while (qr.next())
    {
        salesTable = qr.get(tableNum(SalesTable));

        setPrefix(salesTable.SalesId);

        if (this.process_check(onlyCustStorageFactor))
        {
            salesResrveForMultiThread = new SalesResrveForMultiThread();
            salesResrveForMultiThread.parmsalestable(salesTable);
            salesResrveForMultiThread.pack();
            /*this.batchHeader().addRuntimeTask(salesResrveForMultiThread, this.parmCurrentBatch().RecId, BatchConstraintType::And);
            salesResrveForMultiThread = null;*/

            salesResrveForMultiThread.run();
            i  ;

        }
        n  ;
    }

So it seems like the problem is something to do with the runtimetasks. They are created correctly but inside them I get an error that salestable buffer is null. SalesTable records are extracted correctly because I get inside the loop. Can you help me please?

Can you add client/server side controls to the code and see if there are changeover?

it's easier to examine the moment when the table goes to null in debug, but you may have trouble debugging in batches, so you can simply add isRunningOnServer() to the methods and see which side they are working on.

As for why I'm asking, if there is a client/server side difference in batch and manual work, it means you have a pack/unpack problem.

In a second possibility, if there is more than one AOS, you may be working on a different server from batch (CIL etc. may be problemic)

The main class and class which is executed as runtimetask are both executed on the same AOS server. I checked it in BatchHistory Journal.

As I get it , when I launch class as a batch parameters are packed and everything is executed at AOS server side. Parameters are unpacked before that.

so you can simply add isRunningOnServer() to the methods and see which side they are working on. - I don't get the point. If I put this method to each method when I debug on client it'll return false. Otherwise true. But I can't debug batches. So again I don't see the point.

pack() and unpack() methods of my class salesResrveForMultiThread which is launched as a runtimetask above

public container pack() { return [#CurrentVersion,#CurrentList]; } public boolean unpack(container packedClass) { Version version = RunBase::getVersion(packedClass); ; switch (version) { case #CurrentVersion: [version,#CurrentList] = packedClass; break; default: return false; } return true; }

and #currentlist and #currentversion macros:

class SalesResrveForMultiThread extends runbasebatch { SalesTable salesTable; #define.CurrentVersion(1) #localmacro.CurrentList salesTable #endmacro }

If the entire structure is running on the server or client, the situation I mentioned will not occur, but if there are changeovers, you may lose the value. If you have any doubtfull methods, I recommend you to check it.

Can you try to make a menuItem (runOnServer) to the Class and run it?

Did as you said. When I schedule it as a batch using menuitem then I get the same error. When I untick "batch" option runtimetasks are created and not bound to the main batch because it isn't created and they just get stuck. The main LauncherClass and it's runtimetasks are all executed on the AOS server tier.

If you have any doubtful methods, I recommend you to check it. - Sorry but again I don't get it. All methods are executed on AOS server tier and it can't be different. When I execute classes on the client tier everything works fine. Also pack() and unpack() method look fine.

Resolved the issue. If someone's curious the issue was - you can't pack table buffer without any preparation. I just passed salesId instead:

salesResrveForMultiThread.parmsalesId(salesTable.salesId);

and everything worked fine.

Hi Azat,

you should use macro to prevent this error.

#DEFINE.CurrentVersion(3) #LOCALMACRO.CurrentList your parameter... #ENDMACRO

in the pack method

public container pack() { return [#CurrentVersion,#CurrentList,super()]; }

Hello Hossein,

I use macro:)) The issue was related to the table buffer itself. When I passed salesId instead of the table buffer everything worked fine. I didn't change anything else. Described this in the post above. Anyway thanks.
