I am using Grails 2.0.3 and webFlow 2.0.0.
I have a WebFlow definition in my controller that is working fine but I want to still add integration tests to facilitate future maintenance.
I am getting the following exception in my test whenever the controller attempts to add some value to the flow scope:
ERROR org.codehaus.groovy.grails.webflow.engine.builder.ClosureInvokingAction - Exception occured invoking flow action: No such property: poInfo for class: org.springframework.webflow.core.collection.LocalAttributeMap

This is the part of My WebFlow code that I am trying to test:
def createFlow = {
initialize {
action {
if (params.eventId) {
flow.receivingEventId = params.eventId as int
ReceivingEvent existingReceivingEvent = ReceivingEvent.get(flow.receivingEventId)
flow.receivingEvent = new ReceivingEvent(branch:existingReceivingEvent.branch)
}
}
on ("success").to "addPO"
}
addPO {
on("add") {
log.debug("addPO")
// Initialize flow objects
flow.poInfo = new PoInfo(params)
if (flow.receivingEvent == null) {
flow.receivingEvent = new ReceivingEvent()
}
// validate and populate poInfo object
boolean objectIsValid = flow.poInfo.validateAndPopulate()
if(!objectIsValid) {
if(!flow.poInfo.hasErrors()) {
flash.warning = 'poInfo.poNumber.unknown'
}
return error()
}
// add poInfo object to receivingEvent for additional processing/validation
String errorMessage = flow.receivingEvent.addPoInfo(flow.poInfo)
if(null != errorMessage) {
flash.warning = errorMessage
return error()
} else {
flow.poInfo = null
}
}.to("addPO")
........
And this is my integration test:
class ReceivingEventCreationFlowTests extends WebFlowTestCase{
ReceivingEventController receivingEventController = new ReceivingEventController()
void testInitializeFlow() {
startFlow()
assertCurrentStateEquals "addPO"
}
void testAddPoInfoMissingPiecesPallets() {
println("Hola mundo")
startFlow()
assertCurrentStateEquals "addPO"
receivingEventController.params.poNumber = '63055024UI1063'
receivingEventController.params.pro = '3'
println "flow scope: " + getFlowScope().getClass()
println ("Hola again")
signalEvent('add')
assertTrue getFlowScope().poInfo.hasErrors()
assertCurrentStateEquals "addPO"
}
@Override
public Object getFlow() {
receivingEventController.createFlow
}
String getFlowId() { "create" }
}
Anybody has any ideas on what am I missing here? or if there are any known integration testing issues with webFlow 2.0.0 and grails 2.0.3?
I am following the guidelines from the book: Grails in Action, chapter 9.4: Testing WebFlows... and yet I keep getting the above error.
Thanks in advance,
Jorge Vasquez
