I'm falling short here and need some help. I need to ensure that 'this.fsTok' gets set at the startup before 'this.createServerSiteScratchLayer()' but it seems that no matter what fsTok is always undefined in the createServerSiteScratchLayer() function. fsTok : null startup : function ( ) { this . fsTok = this . getFStokFromUrl ( ) ; this . createServerSideScratchLayer ( ) ; } , getFStokFromUrl : function ( ) { tok = "" var gp = new Geoprocessor ( "gpServiceURL/execute" ) ; var params = { "inSystem" : "someInputParamValue" } ; gp . execute ( params , retTok ) ; function retTok ( results ) { tok = results [ 0 ] . value ; } return tok } , createServerSideScratchLayer : function ( ) { this . serverSideScratchLayer = new FeatureLayer ( this . config . applicationFeatureLayer + '?token=' + this . fsTok , { outFields : [ "OBJECTID" ] } ) ; } ,

Can you try with this instead createServerSideScratchLayer (tok ) You can try to debug the code and see if you are receiving the token and also if the function is approachable. Or alternatively, you can move your code snippet in the response function instead. tok getFStokFromUrl : function ( ) { tok = "" var gp = new Geoprocessor ( "gpServiceURL/execute" ) ; var params = { "inSystem" : "someInputParamValue" } ; gp . execute ( params , retTok ) ; function retTok ( results ) { tok = results [ 0 ] . value ; this . serverSideScratchLayer = new FeatureLayer ( this . config . applicationFeatureLayer + '?token=' + , { outFields : [ "OBJECTID" ] } ) ; } } , Try this if that helps.

this works, thanks. Now it has uncovered an additional scope issue when I try to access this.serverSideScracthLayer from another function.

It's very difficult to inherit code from another developer that has written so many functions that separate out all of the logic. Plus I'm still not fully understanding scope and accessing/setting variables that can be used later on.

Thanks Manish,

I followed your approach but getting "this.createServerSideScratchLayer is not a function" error on this line,

Hi James Crandall,

The code looks correct, however it depends if your gp service is sync or async and whether the function waits till the response is received back.

Ideally, you can check if the response is received and put the createServerSiteScratchLayer() in the getFStokFromUrl function's response.
