To validate the DATA that is in the COACH before the FLOW proceeds to the next step in the service flow, add a validation node to the flow. The validation node can be a nested service or a server script. The server script is the simpler IMPLEMENTATION although the nested service provides greater flexibility.

Example server script:

tw.local.validate = new tw.object.CoachValidation();

if (tw.local.application.name == “”){
tw.system.addCoachValidationError(tw.local.validate, “tw.local.application.name”,
“The name cannot be empty.”);
}
