Custom Control Validator - Sample Code

Create a Custom Validator for control validation

This sample plugin demonstrates custom validation for an individual control. For an example of how to validate an entire screen, refer to the Create a Custom Validator for screen validation example.

About the sample

In this example, we validate the age details entered by the user to ensure it is a number greater than 0 and less than 130.

The sample code demonstrates:

Handling the OnValidateControlEvent event
Extracting the current value of a control and validating it using custom logic
Adding an error to the TransactionResult object in the OnValidateControlEvent event

The sample code needs the following to run:

CustomControlValidator plugin (examples\interview-engine\custom-control-validator)
CustomValidatorExample rulebase (examples\rulebases\compiled\CustomValidatorExample.zip)

To setup this scenario

Copy the rulebase .zip file (CustomValidatorExample.zip) from examples\rulebases\compiled to the rulebase folder in Web Determinations (for example, <webroot>\WEB-INF\classes\rulebases)
Copy and install the CustomControlValidator.jar file (located in examples\interview-engine\custom-control-validator) into Web Determinations; for more information, refer to Create a Plugin. If you wish to modify the CustomControlValidator code, do the following:
1. Copy the code for the CustomControlValidator plugin
2. Modify the validation code in the handleEvent method
3. Compile and JAR or DLL the CustomControlValidator
Run a Web Determinations Interview
