Send previous control to client

Provide the ability to send previous control to client.

There are two ways to send previous control back from the server when a client requests:

• In inbound transformation, set validation_message in result. Previous control will be sent again with message provided in validation_message.
• In inbound transformer, set send_prev_control in result to true, previous control will be sent again. Use this method for Multi-Step controls.

Example script:

(function execute (inputs, outputs) {
  var result = {};
  var request_context = inputs.request_context;
  var typed_value = request_context ['typed_value'];
  if (typed_value.index0f("#") > -1)
    result["validation_message"] = "Invalid character, please don't enter special character '#'";
  result["value"] = typed_value;
  result["search_text"] = "";
  outputs.result - result;
})(inputs, outputs);
