When I call init() I get an error saying the class "Facebook" has not been declared. Every tutorial online has similar code and supposedly works so I'm guessing its a setting somewhere I haven't set because it does look like its getting imported.
My Code:
import flash.display.MovieClip;
import com.facebook.graph.Facebook;
import com.facebook.graph.net.*;
import com.facebook.graph.data.*;
public class A_CLASS extends MovieClip {
protected var _appID:String = "164534125383085";
function A_CLASS():void {
Facebook.init(_appID, logIn);
}
function logIn(session:Object, fail:Object):void {
console.text = "Did Init()";
}
}
My Output:
ReferenceError: Error #1065: Variable com.facebook.graph::Facebook is not defined.

ReferenceError: Error #1065: Variable com.facebook.graph::Facebook is not defined.
that means your program cannot see the reference class please check your Build Path SWC or ANE and build your project then retry

I'm trying to debug a library which uses haxe.macro.TypeTools::findField. I've created a simple code for that:
package;
using haxe.macro.TypeTools;
class Main
{
public function new()
{
var test = findField(Child, "hello");
trace(test);
}
}
class Base
{
private function hello()
{
}
}
class Child extends Base
{
public function new() {}
}
However I'm getting error Unknown identifier : findField. Is this because it can only be used in build macro context?
This is what I'm trying to emulate.
First of all, function findField() is not from the haxe.macro.TypeTools.
It is a helper function from edge.core.macro.Macros.
To use it without a class path, import it's class with a wildcard import edge.core.macro.Macros.*
Secondly, findField() should be used in a build macro context only, since it expects Array<Field>, which is obtained by haxe.macro.Context.getBuildFields().
Timeline code:
import as3.first;
first._this=this;
var str1:String='this is timeline';
Class code:
package as3 {
import flash.display.MovieClip;
public class first extends MovieClip {
public static var _this:Object;
trace(_this.str1);
}
}
Error message:
TypeError: Error #1009: Cannot access a property or method of a null
object reference.
Trying to wrap my mind around how classes work. Need to access timeline functions and variables from class. What am I doing wrong and how can I make this work?
All in all what you are doing is somewhat weird. May be, you just want a document class for your SWF root? You as well could add a class to any movieclip in your library: both ways grant you access to timeline.
package as3
{
import flash.display.MovieClip;
public class first extends MovieClip
{
public static var _this:Object;
trace(_this.str1); // you may place code here... but consider this:
// this area is STATIC, the code here
// executes only once when class gets initialized,
// so, this happens BEFORE you assign first._this=this;
}
}
The following is the code generated by SWTBot Recorder.
public class UserInterfaceTester extends SWTBotEclipseTestCase {
#Test
public void TableTest() {
bot.tree().getTreeItem("wtrt").select();
bot.contextMenu("Expand All").click();
bot.tree().getTreeItem("wtrt").getNode("erwtesg(3)").getNode("esrgg").select();
bot.contextMenu("Open Application Metadata File").click();
bot.text().setText("9.5");
bot.text().setText("Synopsys");
bot.text().setText("3.2");
}
}
But when I try to put that in my Test case to run inside my project it shows error in bot.contextMenu. It says "The method contextMenu(String) is undefined for the type SWTEclipseBot".
Extending SWTBotEclipseTestCase automatically gives me bot object which is
protected SWTEclipseBot bot = new SWTEclipseBot();
But it says it is a deprecated version. It says "Deprecated. use SWTWorkbenchBot. This will be removed from future releases"
Hence I tried
SWTWorkbenchBot bot = new SWTWorkbenchBot(); // by removing extends SWTBotEclipseTestCase
that to did not work. What is the issue? Can some one help?
The ContextMenuHelper class should help with this, and it works round some bugs with dynamic context menus. try:
SWTBotMenu menu =
new SWTBotMenu(ContextMenuHelper.contextMenu(bot.tree(), "Expand All"));
menu.click();
I am new to Mockito and need to learn it for work.
I made a very simple class that has one method that returns a string.
I then made the following test class in eclipse.
import static org.junit.Assert.*;
import org.junit.Test;
import org.mockito.Mockito;
public class No_1Test {
#Test
public void testNo_1() {
No_1 myTest = Mockito.mock(No_1.class);
Mockito.when(myTest.HelloWorld()).thenReturn("Hello World");
String result = myTest.HelloWorld();
Mockito.assertEquals("Hello World", myTest.HelloWorld());
}
}
My understanding of what I have made so far is:
I made a mock class of my No_1 class.
I specified that whenever the HelloWorld() method is called it should return the string ("Hello World")
I stored the results of HelloWorld() into the variable result (which should be "Hello World")
I want to assert that it does what it was meant to do.
The problem is that in eclipse it says that the assertEquals method is undefined for Mockito.
Can someone please point out where I am going wrong here.
You are getting the error like assertEquals method is undefined for mockito because we can't use mockito as in mockito.assertEquals as in your codes try changing it with junit.assertEquals()
And What my experience on mockito says that you should avoid mock classes of the same project,we use to mock classes for which we are dependent on other projects or module,so don't mock No_1 class in your codes and try these codes::
import static org.junit.Assert.*;
import org.junit.Test;
import org.mockito.Mockito;
public class No_1Test {
#Test
public void testNo_1() {
Mockito.when(myTest.HelloWorld()).thenReturn("Hello World");
Junit.assertEquals("Hello World", myTest.HelloWorld());
}
}
And mockito is for mocking java classes or method results but try using junit for your testing as in junit.assertequals
What’s the preferred way to handle 404 errors with Play 2.0 and show a nice templated view?
You can override the onHandlerNotFound method on your Global object, e.g.:
object Global extends GlobalSettings {
override def onHandlerNotFound(request: RequestHeader): Result = {
NotFound(views.html.notFound(request))
}
}
Please note that there are really two different problems to solve:
Showing a custom 404 page when there is "no handler found", e.g. when the user goes to an invalid URL, and
Showing a custom 404 (NotFound) page as a valid outcome of an existing handler.
I think the OP was referring to #2 but answers referred to #1.
"No Handler Found" Scenario
In the first scenario, for "no handler found" (i.e. invalid URL), the other answers have it right but to be more detailed, per the Play 2.1 documentation as:
Step 1: add a custom Global object:
import play.api._
import play.api.mvc._
import play.api.mvc.Results._
object Global extends GlobalSettings {
override def onHandlerNotFound(request: RequestHeader): Result = {
NotFound(
views.html.notFoundPage(request.path)
)
}
}
Step 2: add the template. Here's mine:
#(path: String)
<html>
<body>
<h1>Uh-oh. That wasn't found.</h1>
<p>#path</p>
</body>
</html>
Step 3: tweak your conf/application.conf to refer to your new "Global". I put it in the controllers package but it doesn't have to be:
...
application.global=controllers.Global
Step 4: restart and go to an invalid URL.
"Real Handler can't find object" Scenario
In the second scenario an existing handler wants to show a custom 404. For example, the user asked for object "1234" but no such object exists. The good news is that doing this is deceptively easy:
Instead of Ok(), surround your response with NotFound()
For example:
object FruitController extends Controller {
def showFruit(uuidString: String) = Action {
Fruits.find(uuidString) match {
case Some(fruit) => Ok(views.html.showFruit(fruit))
// NOTE THE USE OF "NotFound" BELOW!
case None => NotFound(views.html.noSuchFruit(s"No such fruit: $uuidString"))
}
}
}
What I like about this is the clean separation of the status code (200 vs 404) from the HTML returned (showFruit vs noSuchFruit).

If you want to do the same using Java instead of Scala you can do it in this way (this works for play framework 2.0.3):
Global.java:
import play.GlobalSettings;
import play.mvc.Result;
import play.mvc.Results;
import play.mvc.Http.RequestHeader;
public class Global extends GlobalSettings {
#Override
public Result onHandlerNotFound(RequestHeader request) {
return Results.notFound(views.html.error404.render());
}
}
Asumming that your 404 error template is views.html.error404 (i.e. views/error404.scala.html).
Please note that Play development team are making lots of efforts to move away from global state in Play, and hence GlobalSettings and the application Global object have been deprecated since version 2.4.
HttpErrorHandler.onClientError should be used instead of
GlobalSettings.onHandlerNotFound. Basically create a class that inherits from HttpErrorHandler, and provide an implementation for onClientError method.
In order to find out type of error (404 in your case) you need to read status code, which is passed as a one of the method arguments e.g.
if(statusCode == play.mvc.Http.Status.NOT_FOUND) {
// your code to handle 'page not found' situation
// e.g. return custom implementation of 404 page
}
In order to let Play know what handler to use, you can place your error handler in the root package or configure it in application.conf using play.http.errorHandler configuration key e.g.
play.http.errorHandler = "my.library.MyErrorHandler"
You can find more details on handling errors here: for Scala or Java.
This works in 2.2.1. In Global.java:
public Promise<SimpleResult> onHandlerNotFound(RequestHeader request) {
return Promise.<SimpleResult>pure(notFound(
views.html.throw404.render()
));
}
Ensure that you have a view called /views/throw404.scala.html
This works in 2.2.3 Play - Java
public Promise<SimpleResult> onHandlerNotFound(RequestHeader request) {
return Promise<SimpleResult>pure(Results.notFound(views.html.notFound404.render()));
}
html should be within /views/notFound404.scala.html
Dont forget to add Results.notFounf() and import play.mvc.Results;
For Java, if you want to just redirect to main page, I solved it by this.
#Override
public Promise<Result> onHandlerNotFound(RequestHeader request) {
return Promise.pure(redirect("/"));
}
