I’m trying to put together a simple process to see if flowable is going to work for my needs. I will basically only be using the Modeler and the api’s. The process will set the dueDate, start a timer that will start another process. I’m struggling with script to set the dueDate and I have no logging or debug capabilities.
this does nothing: execution.setVariable(“dueDate”, “2018-11-17T10:17:43.902+0000”);
the script to start another process works without parameters but doesn’t do anything with parameters:
this works: runtimeService.startProcessInstanceByKey(“Notification”);
this doesn’t:
var notificationParam = new Map();
notificationParam.set(“notificationRoleId”,-11);
runtimeService.startProcessInstanceByKey(“Notification”, notificationParam);
Hi Mark,
by script you mean a groovy scriptTask? would you please provide more details on what you’re trying to accomplish?
I’ve included a very simple example of a process using startProcessInstanceByKey and passing a dueDate variable at the beginning:
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"
xmlns:flowable="http://flowable.org/bpmn"
targetNamespace="http://www.flowable.org/processdef">
<process id="dueDatePlayground" name="dueDatePlayground" isExecutable="true">
<startEvent id="startEvent"/>
<sequenceFlow sourceRef="startEvent" targetRef="theScriptTask"/>
<scriptTask id="theScriptTask" name="Execute script" scriptFormat="groovy">
<script>
def targetDate = execution.getVariable("targetDate")
org.slf4j.LoggerFactory.getLogger("theScriptTask").info("targetDate: {}", targetDate)
</script>
</scriptTask>
<sequenceFlow sourceRef="theScriptTask" targetRef="simpleTask"/>
<userTask id="simpleTask" name="Simple Task" flowable:dueDate="${targetDate}"/>
<sequenceFlow sourceRef="simpleTask" targetRef="theScriptTask"/>
<serviceTask id="reporterTask" name="Very simple variable reporter"
flowable:class="ReporterTaskDelegate"/>
<sequenceFlow sourceRef="reporterTask" targetRef="endEvent"/>
<endEvent id="endEvent"/>
</process>
</definitions>
And the test program you may use to set due dates etc. To run it, simply paste the contents into a text file named sample.groovy and run groovy sample.groovy from console:
import java.time.LocalDate
import java.time.LocalDateTime
import java.time.temporal.ChronoUnit
@Grab(group="ch.qos.logback", module="logback-classic", version="1.2.3")
@Grab(group='com.h2database', module='h2', version='1.4.197')
@Grab(group='org.flowable', module='flowable-engine', version='6.4.0-3')
import org.flowable.engine.*
import org.flowable.engine.delegate.DelegateExecution
import org.flowable.engine.delegate.JavaDelegate
import org.flowable.engine.impl.cfg.StandaloneProcessEngineConfiguration
import org.flowable.engine.runtime.ProcessInstance
import org.flowable.task.api.Task
import org.slf4j.Logger
import org.slf4j.LoggerFactory
class ReporterTaskDelegate implements JavaDelegate {
void execute(DelegateExecution delegateExecution) {
Logger logger = LoggerFactory.getLogger(ReporterTaskDelegate.class)
logger.info("targetDate: {}", delegateExecution.getVariable("targetDate"))
}
}
ProcessEngineConfiguration processEngineConfiguration = new StandaloneProcessEngineConfiguration()
.setJdbcUrl("jdbc:h2:mem:flowable;DB_CLOSE_DELAY=-1")
.setJdbcUsername("sa")
.setJdbcPassword("")
.setJdbcDriver("org.h2.Driver")
.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE)
ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine()
processEngine.getRepositoryService()
.createDeployment()
.addClasspathResource('simpleProcess.bpmn20.xml')
.deploy()
RuntimeService runtimeService = processEngine.getRuntimeService()
LocalDateTime dueDate = LocalDate.now().atStartOfDay().plus(3, ChronoUnit.DAYS);
Map<String, Object> variables = new HashMap<String, Object>()
variables.put("targetDate", dueDate.toString())
ProcessInstance processInstance1 = runtimeService.startProcessInstanceByKey("dueDatePlayground", variables)
TaskService taskService = processEngine.getTaskService()
List<Task> tasks = taskService.createTaskQuery().processInstanceId(processInstance1.getId()).list()
Task firstTask = tasks.get(0)
LoggerFactory.getLogger("sample").info("dueDate: {}", firstTask.getDueDate())
taskService.complete(firstTask.getId())
I just edited previous sample to include an scriptTask in groovy, that should print in console something like:
23:10:30.692 [main] INFO theScriptTask - targetDate: 2018-10-21T00:00
23:10:30.851 [main] INFO sample - dueDate: Sun Oct 21 00:00:00 CEST 2018
23:10:30.862 [main] INFO theScriptTask - targetDate: 2018-10-21T00:100
If you don’t have access to a debugger, don’t use regular groovy print statements, they might not be included in the output.
Hi Mark.
Try to use process debugger which is part of flowable-task app.
https://blog.flowable.org/2018/05/30/process-debugger/
you can easily execute and develop scripts there:

Thank you for the help. I’m unable to post the xml for some reason.
