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

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 ;
