Configure Settings

Configure BeanShell Display Column

When configuring the Beanshell Display Column, you will see the following menu on the right side.

Configure the following properties:

• Label: A custom label for the BeanShell Display Column element. The default value is "BeanShell".
• ID: The ID of the BeanShell Display Column element.
• Script: Custom script in Java. Contains Injected Variables - DataListDisplayColumn column, DataList datalist, Object row & int index

Usage examples

You can use the BeanShell Display Column for different cases. such as:

1. Display a custom string: Input return "flower"; in the Script field.
   
   The runtime will show the following.
   
   
2. Display Number Row in Roman Numerals: Input the code block below in the Script field.
   
   

   int decimalNumber = index + 1;
    
   int[] values = {1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1};
   String[] romanLetters = {"M", "CM", "D", "CD", "C", "XC", "L", "XL", "X", "IX", "V", "IV", "I"};
    
   StringBuilder romanNumber = new StringBuilder();
    
   for(int i = 0; i < values.length; i++){ 
       while(decimalNumber >= values[i]){
           decimalNumber = decimalNumber - values[i];
           romanNumber.append(romanLetters[i]);
       }
   }
    
   return romanNumber;

   The runtime will show the following.
   

3. Display Number Row with Conditional Prefix: Input the code block below in the Script field.
   
   

   int rowNumber = index + 1;
    
   int determinant = rowNumber % 2;
    
   if (determinant == 0){
       return "Even " + rowNumber;
   }
   else if (determinant != 0){
       return "Odd " + rowNumber;
   }
   else{
       return "Error";
   }

   The runtime will show the following.
