I have two functions
1. First one will crated the feature layer
2. second one will access the same created layer and prints the result.
but when i run my script first time it will print the wrong results. when i run it second time it will shows correct result...
Correct Result:
1. layer which is creating contains only 5 Rows so my script is supposed to print only 5 messages
getting access to map layer 1
getting access to map layer 2
getting access to map layer 3
getting access to map layer 4
getting access to map layer 5
Wrong Result Script running 1st Time:
