appl class or object

(1) ShareShare
ReportReport
Posted on by 942
Hello,
 
IN different places in AX 2012 I see reference to this object
 
for instance standard class AifInboundPort
 
 

public void updateServiceHostStatus()

 

{

 

    // If the map is null, then the IL appDomain does not exist and services are not available

 

    serviceStatusMap = appl.getServiceHostStatus();

 

}


what is appl object? I need to check what's inside getServiceHostStatus() method. Pressing F12 doesn't give anything. It can't find it saying /Cannot navigate to definition/.
 
Thanks.
I have the same question (0)

    appl is a special global variable holding an instance of Application class. It's always available, it's located on server tier and it represents the whole application. There is also a similar global variable on client: infolog.
     
    System classes aren't implemented in X++ and therefore you can't see their code. You'll find them under System Documentation node in AOT.

    Hi Martin. Thanks. Hope you are doing fine. I have very strange problem. I have 2 AOS instances and there if a standard form called AifInboundPort. When I stop or start service on one AOS instance and then reopen this form on another AOS instance sometime this started/stopped service is shown as faulty. Howerevre port is deployed. I see this happens here 
     
     

    boolean isPortRunning(AifInboundPort port)

     

    {

     

        str serviceTypeName, status;

     

        boolean isPortStarted = false;

     

    #Aif

     

     

     

        if (port.Deployed)

     

        {

     

            serviceTypeName = strFmt('%1.%2', #DotNetServiceNamespace, port.Name);

     

     

     

            // If the map is null, then the IL appDomain does not exist and services are not available

     

            if (serviceStatusMap && serviceStatusMap.exists(serviceTypeName))

     

            {

     

                status = serviceStatusMap.lookup(serviceTypeName);

     

                isPortStarted = strStartsWith(status, openedCommunicationStateName);

     

     

     

                if (isPortStarted)

     

                {

     

                    // A status for the listener is returned only for an MSMQ port

     

                    status = this.getMSMQListenerStatus(port.Name);

     

                    if (status != '')

     

                    {

     

                        // For an MSMQ port, the queue listener status should be checked too

     

                        isPortStarted = strStartsWith(status, openedCommunicationStateName);

     

                    }

     

                }

     

            }

     

        }

     

     

     

        return isPortStarted;

     

    }


    this line - if (serviceStatusMap && serviceStatusMap.exists(serviceTypeName))


     

    serviceStatusMap doesn't contain my newly started/stopped service and therefore is shown as faulty on another AOS instance. isPortStarted is returned as false.

     

    map is generated here

     

    serviceStatusMap = appl.getServiceHostStatus();

     

    it is called form executequery() method of the main form datasource inside method    element.updateServiceHostStatus();



    public void executeQuery()


    {


        super();


        // Get the updated port status


        element.updateServiceHostStatus();


    }


     

    This happens from time to time. Sometimes it works fine, I start/stop port on one AOS instance and then check the same form on another AOS instance and it looks good. I think this is glitch or bug. I don't understand why sometimes serviceStatusMap contains my newly stopped/started service and sometimes not. Also this happens with all ports. Not only with particular one.
