I have a dmn file (attached) in which I want to test whether one of the variables is empty. The evaluation is failing with ‘Exception while evaluating decision with key ‘null’’. The input variable is a type date and the input value is null. Is there another approach?
I am calling this Decision within a groovy script below, in which the variable followUpDate is null.
def setPriority(taskName) {
def dmnEngine = task.execution.getProcessEngineServices().getDecisionService()
def rush = task.execution.getVariable("rush")
def followUpDate = task.execution.getVariable("followUpDate")
def clientDueDate = task.execution.getVariable("clientDueDate")
println("Rush: " + rush)
println("FollowUp Date: " + followUpDate)
println("ClientDue Date: " + clientDueDate)
def dmnKey = "TaskPriority_1"
def variables = Variables
.putValue("rush", rush)
.putValue("task", taskName)
.putValue("followUpDate", followUpDate )
.putValue("clientDueDate", clientDueDate)
result = dmnEngine.evaluateDecisionTableByKey(dmnKey, variables)
def priorityLevel = result.getSingleResult().get("priorityLevel")
def priorityDate = result.getSingleResult().get("priorityDate")
task.setVariableLocal("priorityLevel",priorityLevel)
task.setVariableLocal("priorityDate",priorityDate)
TaskPriority.dmn (6.6 KB)
