I am new Web App development using Flex Builder 3 and currently I am facing the following problem:
Attached is a code snippet from the mxml file:
<mx:Script>
<![CDATA[
import com.bx.Char10;
import com.bx.A;
[Bindable] private var inputParam:A = new A()
inputParam.CustNumber.char10 = '0123456789'
}
]]>
</mx:Script>
This Gives a compile error
1120 Access of undefined property inputParam
However if I replace
inputParam.CustNumber.char10 = '0123456789'
with
private function set():void
{
inputParam.CustNumber.char10 = '0123456789'
}
The compile error goes away.
My Question is :
How can I remove this Compilation Error without using the workaround I did?
Hmm, I don't believe that one can execute arbitrary statements directly inside a class body. (The "Script" tag's contents are treated as if they were directly inside the class body).
Only function definitions or variable property definitions are allowed.
A different work-around to use is to pass the information through the constructor of the variable property you're interested in.
[Bindable] private var inputParam:A = new A('0123456789')

I recently switched to Java 11 for a rather big project, and would like to switch to using var class = new Class() instead of Class class = new CLass().
I tried using Intellij Structural Search (and replace) for this, but its turning out to be more complex than expected.
My first attempt was $Type$ $Inst$ = new $Constructor$($Argument$);, which also matches global variables (which don't allow var).
My second attempt is:
class $Class$ {
$ReturnType$ $Method$ ($ParameterType$ $Parameter$) throws $ExceptionType$ {
$Statements$;
final $Type$ $Inst$ = new $Constructor$($Argument$);
$Statements2$;
}
}
Which misses all calls inside e.g. try blocks (since they get matched by the expressions)
Any help would be greatly appreciated!
Use your first template
$Type$ $Inst$ = new $Constructor$($Argument$);
But add a Script modifier on the $Inst$ variable with the following text:
Inst instanceof com.intellij.psi.PsiLocalVariable
Alternatively you may want to try the Local variable type can be omitted inspection that is available in IntelliJ IDEA.
I have setup the JavaSymbolSolver like below:
Instance Variables:
private CombinedTypeSolver combinedTypeSolver = new CombinedTypeSolver();
private JavaSymbolSolver symbolSolver;
private ParserConfiguration parserConfiguration = new
ParserConfiguration();
private JavaParser parser;
private CompilationUnit compilationUnit = null;
private ParseResult<CompilationUnit> parseResultcompilationUnit = null;
from constructor:
this.combinedTypeSolver.add(new ReflectionTypeSolver());
this.combinedTypeSolver.add((new JavaParserTypeSolver("C:\\Users\\nfountou\\git\\TestingJavaParser\\rsc")));
this.combinedTypeSolver.add((new JavaParserTypeSolver("C:\\Users\\nfountou\\git\\TestingJavaParser")));
this.symbolSolver = new JavaSymbolSolver(this.combinedTypeSolver);
this.parserConfiguration.setSymbolResolver(this.symbolSolver);
this.parser = new JavaParser(parserConfiguration);
FileInputStream in = new FileInputStream(filepath);
this.parseResultcompilationUnit = this.parser.parse(in);
this.compilationUnit = parseResultcompilationUnit.getResult().get();
The test code seems to work fine and I am being able to resolve e.g. class B
of class A as can be seen below:
public class A extends B{
}
the problem is that it seems that I cannot resolve anything else and whatever I tried I receive the message below:
Exception in thread "main" java.lang.IllegalStateException: No data of this type found. Use containsData to check for this first.
For example the source code that I am running for resolving e.g an AssignExpr:
ResolvedType declaringType = ((AssignExpr) value).calculateResolvedType();
(where value is an object that holds an AssignExpr node)
Resolving a superclass works fine and returns the right values:
ResolvedClassDeclaration declaringType = ((ClassOrInterfaceType) value).resolve().getTypeDeclaration().asClass();
Any ideas what am I doing wrong?
I found what was the issue... Source code is fine and it passes the configuration to the parser in the right way. The problem was that as I was refactoring code, I created a class and named it "SymbolSolver" which was causing the problem as javaparser uses a class with that specific name...
Also another problem was that I was using wrapppedNode Nodes which do not hold the configuration from symbolsolver.
In another question I was advised to use ScalaJS bundler to import NPM dependencies.
I would like to use some Javascript NPM packages in a simple client-only web application. There is an example called static which shows this.
My changes to the example:
Add into build.sbt:
npmDependencies in Compile += "esprima" -> "3.1.3"
Add into Main.scala:
import Esprima._
import JsonToString._
val code = "answer = 42"
val tokens = tokenize(code)
val tokensStr = tokens.json
Change in Main.scala: "This is bold" into s"This is bold $tokensStr"
Facade (a bit simplified, for full a version see GitHub):
import scala.scalajs.js
import scala.scalajs.js.annotation.JSName
#JSName("esprima")
#js.native
object Esprima extends js.Object {
def tokenize(input: String, config: js.Any = js.native, delegate: String => String = js.native): js.Array[js.Any] = js.native
def parse(input: String, config: js.Any = js.native): js.Dynamic = js.native
}
When running the html generated with fastOptJS::webpack the error is:
Uncaught TypeError: Cannot read property 'tokenize' of undefined
Inspecting the static-fastopt-bundle.js shows esprima is used, but its js is not bundled.
What other steps are needed to add dependencies into a client-only web page?
As described in this part of the documentation, you have to use #JSImport in your facade definition:
#JSImport("esprima", JSImport.Namespace)
For reference, #JSName defines a facade bound to a global name, while #JSImport defines a facade bound to a required JavaScript module.
I'm using TypeScript and require.js to resolve dependencies in my files. I'm in a situation where I want to reference a static field of a class in an other file, but in the same internal module (same folder) and I am not able to access it, even if the Visual Studio pre-compiler does not show any error in my code.
I have the following situation :
Game.ts
class Game {
// ...
static width: number = 1920;
// ...
}
export = Game;
Launcher.ts
/// <reference path='lib/require.d.ts'/>
import Game = require("Game");
var width: number = Game.width;
console.log(width); // Hoping to see "1920"
And the TypeScript compiler is ok with all of this. However, I keep getting "undefined" at execution when running the compiled Launcher.ts.
It's the only reference problem I'm having in my project, so I guess the rest is configured correctly.
I hope I provided all necessary information, if you need more, please ask
Any help is appreciated, thanks !
Your code seems sound, so check the following...
You are referencing require.js in a script tag on your page, pointing at Launcher (assuming Launcher.ts is in the root directory - adjust as needed:
<script src="Scripts/require.js" data-main="Launcher"></script>
Remove the reference comment from Launcher.ts:
import Game = require("Game");
var width: number = Game.width;
console.log(width); // Hoping to see "1920"
Check that you are compiling using --module amd to ensure it generates the correct module-loading code (your JavaScript output will look like this...)
define(["require", "exports", "Game"], function (require, exports, Game) {
var width = Game.width;
console.log(width); // Hoping to see "1920"
});
If you are using Visual Studio, you can set this in Project > Properties > TypeScript Build > Module Kind (AMD)
If you are using require.js to load the (external) modules, the Game class must be exported:
export class Game {}
If you import Game in Launcher.ts like
import MyGame = require('Game')
the class can be referenced with MyGame.Game and the static variable with MyGame.Game.width
You should compile the ts files with tsc using option --module amd or the equivalent option in Visual Studio
I have a Document class that loads variables from Facebook with the use of stage.loaderInfo
var connect:FacebookConnectObject = new FacebookConnectObject( facebook, API_KEY, this.stage.loaderInfo );
But when I change the Document class (with another one responsible for the layout of my app), and try call the above from a movieclip that exists in my application with the use:
var facebook_class:FacebookAp = new FaceBppkApp
addChild(facebook_class) I get error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I believe the error comes fro this line
this.stage.loaderInfo
since I changed the scope...
How I am supposed to fix that?
According to a post by Devonair: Seems 99 times out of a 100 when people have a problem with a 1009 error, it's because the stage property is inaccessible.
so I used this snippet
public function start() {
if
{(stage) init();}
else
{ addEventListener(Event.ADDED_TO_STAGE, init);
}
}
private function init(event:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, init);
// everything else...
}
In case sb has the same problem...
