Configure Script tasks

To start a Business Process by a timer, you can use a script task with the following properties:

• execution.setVariable("ext_tenantId", "manufacturing");

• execution.setVariable("initiator","10015");

Uwaga: The wfc_url parameter is optional and not needed to initialize the script task.

You can start a Business Process with an initialization script task that automatically imports data — such as person or group information — for use throughout the process. This can improve performance by reducing the number of times to import data. You can add a timer start event just before the script task to start the process at a specific time. Or an initial user task could require a person to enter information in a form from the Control Center to start the process.

1. Insert a Script Task immediately after the start event.

    Script task

   Executes a script to directly access Java beans in the configuration as well as task and execution beans. Script tasks achieve most of the same functions of a Java class.

2. Select the script task. In properties:
   1. Enter a Name. Example: Init or Initialize
   2. In Script Format, enter groovy.
   3. Select Script.

   4. Enter an array of user or group IDs.

      Example initialization of an assigneeList process variable

      import com.activiti.domain.idm.User;

      import com.activiti.security.SecurityUtils;

      out.println('Start - Initialize moving estimate');

      User currentUser = SecurityUtils.getCurrentUserObject();

      ArrayList idList = new ArrayList();

      Long tenantId = currentUser.getTenantId();

      List<User> users = userService.getAllUsers(0,999,tenantId);

      for (User u : users) {

      idList.add(u.getId());

      }

      execution.setVariable('assigneeList', idList);

      out.println('End - Initialize moving estimate');

You can access form field values by way of a script task with the following properties:

• var varName = execution.getVariable("FormFieldID");

• FormFieldID is the ID associated with that form field.
• The value of this field is the value of the form field.
• In the case of radio buttons and drop-down selection lists, the value is the ID of the selected button or value. Example: You can get the selected value of a radio button.

To get access to a variable that is created in a script outside the script task, you must set it as an execution variable in the script as follows:

• execution.setVariable("varName", “varValue”);

Execution variables are accessible outside of scripts, for example in service task properties and forms, as follows:

• ${executionVariableName}

This pre-configured Business Process Model sends reminder notifications.

• Validate Employee ID: Verify that the employee identification number is specified; if not, send an error message.

  var EmployeeID = execution.getVariable("EmployeeID");

  if(EmployeeID == null || EmployeeID.isEmpty() ){

  execution.setVariable("ErrorString","Missing EmployeeID");

  }

• Validate Generic Notification Name:
  • Verify that the notification is specified; if not, send an error message.
  • Similar script to Validate Employee ID
• Exclusive Gateway:
  • If the notification timer ${GenNotificationTimerDuration == "} is specified, calculate the delay.
  • If not, use the default date based on GenNotificationDate.
• TimerCatchEvent: Set the delay (Calculate Delay or Set Default Delay) before continuing the process.

• Send Generic Notification: Send the notification. The execution variables are defined in the Generic Notification API Service Task and provide the input parameters for the notification.

requestItemsList = execution.getVariable("RequestedItems");

execution.setVariable("CUSTOM_VALIDATE_RESULT", "1");

var hasReqOn = execution.getVariable("hasRequestOn");

var canSubmitRequest = execution.getVariable("CanSubmitRequestForApproved");

if(canSubmitRequest == "false"){

execution.setVariable("showErrorMsg", "true");

}

var showErrorMsg = execution.getVariable("showErrorMsg");

if(hasReqOn == "true" || showErrorMsg == "true"){

execution.setVariable("CUSTOM_VALIDATE_RESULT", "0");

execution.setVariable("CUSTOM_VALIDATE_ERROR_MESSAGE", "The request conflicts with a previously approved request. Verify the information in the request and submit again.");
