Hi guys
I'm trying to get some "hardcoded" values from an apex Method, but when I write a console.log it's comming empty.
Here's the code I'm working on:
#wire(getValues)
wiredValues({error, data})
if(data) {
console.log("Data::::::",data);
this.getVal = JSON.stringify(data);
} else if(error){
this.error = error;
this.getVal = undefined;
console.log("No values");
}
Here's my apex method(I'm trying to make kind of "fake" callout but i'm not sure if im right):
public without sharing class getSomeValues {
#AuraEnabled(cacheable = true)
public static List<wrapVal> getWrapVal() {
HttpResponse request = new HttpResponse();
request.setBody('{"Values": ["1000", "2000", "3000", "4000", "5000"]}');
Map<String, Object> results = (Map<String, Object>)
JSON.deserializeUntyped(request.getBody());
List<Object> sumVal = (List<Object>) results.get('Values');
List<wrapVal> newLstValues = new List<wrapVal>();
for (Object getValues : sumVal ) {
wrapVal newLstValue = new wrapVal();
newLstValue.nwValue = String.valueOf(getValues);
newLstValues.add(newLstValue);
System.debug("getValues::::::"+ newLstValue.nwValue);
}
return newLstValues;
}
public class wrapVal {
public String nwValue { get; set; }
}
Debug:
So idk what i'm doing wrong, if can share with me some advice or documentation it'd be great.
Thanks
It seems like you need to decorate the properties of the class wrapVal with #AuraEnabled. Otherwise LWC won't receive them.
public class wrapVal {
#AuraEnabled
public String nwValue { get; set; }
}

I have a .NET Core 2.1 application. In Startup.cs configuration method, I use:
services.AddDbContext<ApplicationDbContext>(options =
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
...
services.AddMemoryCache();
Then in my controller:
public class DropDownListController : Controller
{
private readonly ApplicationDbContext _context;
private readonly IMemoryCache _memoryCache;
private const string ProvidersCacheKey = "providers";
private const string AgenciesCacheKey = "agencies";
public DropDownListController(ApplicationDbContext context, IMemoryCache memoryCache )
{
_context = context;
_memoryCache = memoryCache;
}
}
and in the controller also, the method to get the dropdownlist:
public JsonResult GetProvider()
{
IEnumerable<DropDownListCode.NameValueStr> providerlist;
if (_memoryCache.TryGetValue(ProvidersCacheKey, out providerlist))
{
return Json(providerlist);
}
else
{
MemoryCacheEntryOptions cacheExpirationOptions = new MemoryCacheEntryOptions();
cacheExpirationOptions.AbsoluteExpiration = DateTime.Now.AddDays(30);
cacheExpirationOptions.Priority = CacheItemPriority.Normal;
DropDownListCode um = new DropDownListCode(_context);
var result = um.GetProviderList();
_memoryCache.Set(ProvidersCacheKey, result);
return Json(result);
}
}
When I set a breakpoint on the line:
return Json(providerlist);
I see the ProvidersCacheKey is in the _memoryCache, but it has no value.
What happened to the data?
When I do a Quick Watch on _memoryCache, I can see the DbContext object was destroyed. But how can that be, the code works fine but the cache object does not have the data I saved to it.
Any help would be appreciated.
The method to get providers is:
public IEnumerable<NameValueStr> GetProviderList()
{
var providerlist = (from a in _context.AgencyProvider
where a.Provider == a.AgencyId
select new NameValueStr
{
id = a.Provider,
name = a.Name
});
return providerlist.Distinct();
}
Adding "ToList()" in the calling method worked:
MemoryCacheEntryOptions cacheExpirationOptions = new MemoryCacheEntryOptions();
cacheExpirationOptions.AbsoluteExpiration = DateTime.Now.AddMinutes(30);
cacheExpirationOptions.Priority = CacheItemPriority.Normal;
DropDownListCode um = new DropDownListCode(_context);
var result = um.GetProviderList().ToList();
_memoryCache.Set(ProvidersCacheKey, result);
return Json(result);

I need to add typing indicator activity inside the form flow, I have used the following code but it only works out side of form flow, once the user enter the form builder the typing indicator does not appear.
Activity replytyping1 = activity.CreateReply();
replytyping1.Type = ActivityTypes.Typing;
replytyping1.Text = null;
ConnectorClient connector2 = new ConnectorClient(new Uri(activity.ServiceUrl));
await connector2.Conversations.ReplyToActivityAsync(replytyping1);
I am using the following code inside dialog to call the form builder:
var myform = new FormDialog<TrainingForm>(new TrainingForm(), TrainingForm.MYBuildForm, FormOptions.PromptInStart, null);
context.Call<TrainingForm>(myform, AfterChildDialog);
my form builder code:
public enum MoreHelp { Yes, No };
public enum Helpfull { Yes, No };
[Serializable]
public class TrainingForm
{
public string More = string.Empty;
public string usefull = string.Empty;
[Prompt("Is there anything else I can help you with today? {||}")]
[Template(TemplateUsage.NotUnderstood, "What does \"{0}\" mean?", ChoiceStyle = ChoiceStyleOptions.Auto)]
public MoreHelp? needMoreHelp { get; set; }
[Prompt("Was this helpful? {||}")]
[Template(TemplateUsage.NotUnderstood, "What does \"{0}\" mean?", ChoiceStyle = ChoiceStyleOptions.Auto)]
public Helpfull? WasHelpful { get; set; }
public static IForm<TrainingForm> MYBuildForm()
{
return new FormBuilder<TrainingForm>()
.Field(new FieldReflector<TrainingForm>(nameof(needMoreHelp))
.SetActive(state => true)
.SetNext(SetNext2).SetIsNullable(false))
.Field(new FieldReflector<TrainingForm>(nameof(WasHelpful))
.SetActive(state => state.More.Contains("No"))
.SetNext(SetNext).SetIsNullable(false)).OnCompletion(async (context, state) =>
{
if (state.usefull == "No")
{
await context.PostAsync("Sorry I could not help you");
}
else if (state.usefull == "Yes")
{
await context.PostAsync("Glad I could help");
}
if(state.More == "Yes")
{
await context.PostAsync("Ok! How can I help?");
}
context.Done<object>(new object());
})
.Build();
}
If you are attempting to send the typing activity from the dialog that loaded the FormFlow dialog, it will not work because the code in the parent dialog does not execute every time the FormFlow dialog is loaded.
However, you can modify the MessagesController and inspect the dialog stack. If the FormFlow dialog is the last dialog on the stack, then send typing:
public async Task<HttpResponseMessage> Post([FromBody]Activity activity) {
if (activity.Type == ActivityTypes.Message)
{
using (var scope = DialogModule.BeginLifetimeScope(Conversation.Container, activity))
{
var botData = scope.Resolve<IBotData>();
await botData.LoadAsync(default(CancellationToken));
var stack = scope.Resolve<IDialogTask>();
if (stack.Frames != null && stack.Frames.Count > 0)
{
var lastFrame = stack.Frames[stack.Frames.Count - 1];
var frameValue = lastFrame.Target.GetType().GetFields()[0].GetValue(lastFrame.Target);
if(frameValue is FormDialog<TrainingForm>)
{
var typingReply = activity.CreateReply();
typingReply.Type = ActivityTypes.Typing;
var connector = new ConnectorClient(new Uri(activity.ServiceUrl));
await connector.Conversations.ReplyToActivityAsync(typingReply);
}
}
}
await Conversation.SendAsync(activity, () => FormDialog.FromForm(TrainingForm.MYBuildForm));
}
else
{
this.HandleSystemMessage(activity);
}
return Request.CreateResponse(HttpStatusCode.OK);
}
As you can see, all rules can be listed in project explorer, i am wondering Drools workbench has such a Rest API for this, but I went through online document document, there is no such API. any suggestion on this? thanks in advance.
https://docs.jboss.org/drools/release/latest/drools-docs/html/ch20.html#d0e22619

As far as I know, there is no REST API to do that (public at least). One option do you have though is to use git to get that information from the workbench.
The storage of the workbench is based on git. Each repository in the workbench is actually a git repository. The workbench allows you to clone those repositories and to do whatever you need with them just as with any other git repo out there.
Inside each of the git repositories you will find zero or more maven projects. Indeed, each of the projects you see in the workbench is a real maven project. The different assets in your projects (drl rules, guided rules, decision table, etc.) will be available under the resources directory of the corresponding project.
Hope it helps,
As Esteban Aliverti mentioned, there is no ready to use API to achieve this. However, we can write a custom extension to KIE Server to fetch all the rules deployed.
It is explained in detailed here.
I have similar use case in my application and did the following implementation for fetching rules.
CusomtDroolsKieServerApplicationComponentsService
public class CusomtDroolsKieServerApplicationComponentsService implements KieServerApplicationComponentsService {
private static final String OWNER_EXTENSION = "Drools";
public Collection<Object> getAppComponents(String extension, SupportedTransports type, Object... services) {
// skip calls from other than owning extension
if (!OWNER_EXTENSION.equals(extension)) {
return Collections.emptyList();
}
RulesExecutionService rulesExecutionService = null;
KieServerRegistry context = null;
for (Object object : services) {
if (RulesExecutionService.class.isAssignableFrom(object.getClass())) {
rulesExecutionService = (RulesExecutionService) object;
continue;
} else if (KieServerRegistry.class.isAssignableFrom(object.getClass())) {
context = (KieServerRegistry) object;
continue;
}
}
List<Object> components = new ArrayList<Object>(1);
if (SupportedTransports.REST.equals(type)) {
components.add(new RuleRESTService(rulesExecutionService, context));
}
return components;
}

You can make a REST call to Kie Server from you application to access all the rules available for the given container.
http://localhost:8080/kie-server/services/rest/server/containers/instances/<container-id>/ksession/<session-id>
I'm experiencing a problem when D&D a custom object from Swing to JavaFX and I'm wondering if I'm doing something wrong or its probably a Java FX bug.
My Transferable has been defined as the following:
public class TransferableEmployee implements Transferable {
public static final DataFlavor EMPLOYEE_FLAVOR = new DataFlavor(Employee[].class, "Employee");
public static final DataFlavor DEFINITION_FLAVOR = new DataFlavor(PropertyDefinition[].class, "Definition");
private static final DataFlavor FFLAVORS [] = {EMPLOYEE_FLAVOR, DEFINITION_FLAVOR};
private Employee[] employees;
private PropertyDefinition[] propertyDefinitions;
public MintTransferableEmployee(Employee[] employees, PropertyDefinition[] propertyDefinitions) {
this.employees = employees != null ? employees.clone() : null;
this.propertyDefinitions = propertyDefinitions != null ? propertyDefinitions.clone() : null;
}
public DataFlavor[] getTransferDataFlavors() {
return FFLAVORS.clone();
}
public Object getTransferData(DataFlavor aFlavor) throws UnsupportedFlavorException {
Object returnObject = null;
if (aFlavor.equals(EMPLOYEE_FLAVOR)) {
returnObject = employees;
}
else if(aFlavor.equals(DEFINITION_FLAVOR)){
returnObject = propertyDefinitions;
}
else{
throw new UnsupportedFlavorException(aFlavor);
}
return returnObject;
}
public boolean isDataFlavorSupported(DataFlavor aFlavor) {
boolean lReturnValue = false;
for (int i=0, n=FFLAVORS.length; i<n; i++) {
if (aFlavor.equals(FFLAVORS[i])) {
lReturnValue = true;
break;
}
}
return lReturnValue;
}
}
I've created an imageView (FX Component) where I added the setOnDragOver just as the following:
employeePhotoImageView.setOnDragOver(new EventHandler<DragEvent>() {
#Override
public void handle(DragEvent event) {
System.out.println("dragOver");
event.getDragboard().getContentTypes();
event.getDragboard().getContent(DataFormat.lookupMimeType("application/x-java-serialized-object"));
}
});
The getContentTypes() returns a Map with [[application/x-java-serialized-object]], so now I try to get the Content, and this only returns the List of PropertyDefinition but no Employee at all (which in this case, is the one I need).
If I remove the data of the PropertyDefinition in the transferable, the employee is returned in the getContent(DataFormat) method.
For me, this means that JavaFX only works with 1 DataFlavor or somehow it is only returning the last flavor found in the Transferable.
Any clues on this?
Thanks in advanced...
I have an MVC 2 app that I want all requests to return json. I have overridden a HandleErrorAttribute and an AuthorizeAttribute. My goal is that all errors (even 403 and 404) are returned as json.
Here is my error handler. ExceptionModel is a simple class defining any error returned by my application. The Exception handler is a class that translates the error details into a formatted e-mail and sends it to me.
public class HandleErrorJsonAttribute : System.Web.Mvc.HandleErrorAttribute
{
public override void OnException(ExceptionContext context)
{
context.ExceptionHandled = true;
RaiseErrorSignal(context.Exception);
context.RequestContext.HttpContext.Response.ContentType = "application/json";
JsonSerializer serializer = new JsonSerializer();
serializer.Serialize(context.HttpContext.Response.Output, new ExceptionModel(context.Exception));
}
private static void RaiseErrorSignal(Exception ex)
{
IExceptionHandler handler = Resolve();
handler.HandleError(ex.GetBaseException());
}
private static IExceptionHandler Resolve()
{
return ServiceLocator.Locate<IExceptionHandler>();
}
}
Here is the Exception model for clarification
public class ExceptionModel
{
public int ErrorCode { get; set; }
public string Message { get; set; }
public ExceptionModel() : this(null)
{
}
public ExceptionModel(Exception exception)
{
ErrorCode = 500;
Message = "An unknown error ocurred";
if (exception != null)
{
if (exception is HttpException)
ErrorCode = ((HttpException)exception).GetHttpCode();
Message = exception.Message;
}
}
public ExceptionModel(int errorCode, string message)
{
ErrorCode = errorCode;
Message = message;
}
}
and finally, my custom authorize attribute. I an using forms auth, but I did not want any of the automatic redirection. I simply want the error to show on the screen and stop any further processing.
public class AuthorizeTokenAttribute : System.Web.Mvc.AuthorizeAttribute
{
public bool SuperAdminOnly { get; set; }
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
bool authorized = base.AuthorizeCore(httpContext);
if(!SuperAdminOnly)
return authorized;
if(!authorized)
return authorized;
return SessionHelper.UserIsSuperAdmin(httpContext.User.Identity.Name);
}
protected override void HandleUnauthorizedRequest(System.Web.Mvc.AuthorizationContext filterContext)
{
throw new HttpException(403, "Access Denied");
}
}
This all works great for most errors, but it is missing one thing. I have a controller action like this.
[AuthorizeToken]
[HttpPost]
public JsonResult MyAction()
{
return new JsonResult();
}
It works fine when you submit via post, but on a get I receive an unhandled 404 error.
Server Error in '/' Application.
The resource cannot be found.
Description: HTTP 404. The resource
you are looking for (or one of its
dependencies) could have been removed,
had its name changed, or is
temporarily unavailable. Please
review the following URL and make sure
that it is spelled correctly.
Requested URL: /MyController/MyAction
Version Information: Microsoft .NET
Framework Version:4.0.30319; ASP.NET
Version:4.0.30319.1
This happens on a GET, which is to be expected as default behavior. However, how can I handle for this condition so that I could instead return json like this
{"ErrorCode":404,"Message":"Page Not Found"}
To handle errors personally I prefer the Application_Error event in Global.asax:
protected void Application_Error(object sender, EventArgs e)
{
var exception = Server.GetLastError();
Response.Clear();
Server.ClearError();
var httpException = exception as HttpException;
var routeData = new RouteData();
routeData.Values["controller"] = "Errors";
routeData.Values["action"] = "Index";
routeData.Values["error"] = exception;
IController errorController = new ErrorsController();
errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
}
and then have an ErrorsController:
public class ErrorsController : Controller
{
public ActionResult Index(Exception exception)
{
var errorCode = 500;
var httpException = exception as HttpException;
if (httpException != null)
{
errorCode = httpException.ErrorCode;
}
return Json(new
{
ErrorCode = errorCode,
Message = exception.Message
}, JsonRequestBehavior.AllowGet);
}
}
