Hi, I have a problem with javascript.
The strange thing is that there is this error when I run the application on localhost - appears only on the production server

Exception

Error while executing JavaScript computed expression
Script interpreter error, line=10, col=14: 'range' is undefined and cannot be accessed as an array

JavaScript code

   1: var range = @DbColumn("","data",1);
   2: 
   3:     function rand(range_from,range_to)
   4:         {
   5:             var r = Math.random();
   6:             r = r * (range_to-range_from) + range_from;
   7:             return Math.round(r);
   8:         }
   9: 
  10: var result = range[rand(0,range.length-1)];
  11: 
  12: return result

Hi,
 
you are trying to access a undefined value, that is why it is not working. 
Maybe the lookup is not correct. Please check your @DBColumn: Is the view existing / a view index build?
 
Hope this helps 
Sven

Everything seems to be correct.
Is there another way to get a random value from a column?

This happens if @DbColumn has no returning value.

In the column, there are some values.
The strange thing is that the error only occurs on the server.
