Create Thing Dynamically OK but doesn't appear in Composer until reboot !!

[pjoly]

Hello

I'm creating things when not existing using code recommandations.

It works fine, I can use the things in services, MAshups ... but it doesn't appear in the list of things of the composer.

restart tomcat8 : not OK

reboot server : OK

any ideas ?

my code :

try {  
    var params = {  
        name: DeviceName,  
        description: "This is a device automatically created on data reception at " + today,  
        thingTemplateName: "MyTemplate"  
    };  
    Resources["EntityServices"].CreateThing(params);  
   // Always enable and restart a new thing to make it active on the Platform  
    Things[DeviceName].EnableThing();  
    Things[DeviceName].RestartThing();  
  	
      // Any code that could potentially cause an exception should  
    // also be included in the try-catch block.  
    logger.debug ( logprefix + DeviceName + " created !!!");
}  
catch (err) {  
    // If an exception is caught, we need to attempt to delete everything  
    // that was created to roll back the entire transaction.  
    // If we do not do this a "ghost" entity will remain in memory  
    // We must do this in reverse order of creation so there are no dependency conflicts  
    // We also do not know where it failed so we must attempt to remove all of them,  
    // but also handle exceptions in case they were not created  
     
    logger.debug ( logprefix + DeviceName + " EXCEPTION! = " + err + " --- to be deleted" );

 
    try {  
        var devicename = devicename ;
        var params = {name: DeviceName};  
        Resources["EntityServices"].DeleteThing(params);  
        logger.debug ( logprefix + DeviceName + " deleted !");

    }  
    catch(ex2) {//Thing was not created  
            logger.debug ( logprefix + DeviceName + " not deleted ! EXCEPTION! = " + ex2);

    }  
}  

result = DeviceName ;

Hi @pjoly does it behaves the same if you were to manually call the CreateThing service? I tried testing it by calling CreateThing in a loop all created things shows up for me without any reboot.

Which ThingWorx version are you on?

Hello @supandey

Yes if I create the thing manually with the composer or if I call manually the service from the composer,  I can see it directly in the list of things.

I'm using Thingworx 7.4.9

FYI the service to create the thing is called from MQTT subscriber (user is system) . But the thing is well created, just not displayed

Regards

@pjoly sorry for some delay in getting back to this, I could not reproduce this issue so far, even when i have the thing creation service automatically triggered based on a dummy event raised by a Timer i tested this on v8.3.1. Based on the the timer event thing gets created and i can instantly see that once i navigate to the ThingWorx Composer > Things

Have you tried this on any other ThingWorx version?
