I'm using the Bootjack Datepicker and after upgrading Dart to 1.12.1, I'm all of a sudden seeing only half a calendar with no days and with this exception:
Exception: No static getter 'trusted' declared in class
'NodeTreeSanitizer'. NoSuchMethodError: method not found: 'trusted'
Receiver: Type: class 'NodeTreeSanitizer'
This is the only line of code needed to wire the calendar:
Calendar.use();
If you need to manually wire the calendar, you can manually call:
Calendar.wire(querySelector("div.calendar"));
Both of them are giving me the exception in calendar.dart
The code that seems to be breaking is:
void _dayView() {
TableElement calBody = element.querySelector('.cnt');
Element dow = calBody.tBodies[0].createFragment(_DOW_TEMPLATE).children[0];
List<Element> children = dow.children;
List<String> swkDays = _dfmt.dateSymbols.SHORTWEEKDAYS;
int ofs = (_firstDayOfWeek + 1) % 7;
//render week days
for (int i = swkDays.length; --i >= 0;) {
children[i].text = swkDays[(i + ofs) % 7];
}
var buffer = new StringBuffer();
for (int i = 6; --i >= 0;) {
buffer.write(_DAYROW_TEMPLATE);
}
calBody.tBodies[0]
..append(dow)
..appendHtml(buffer.toString(), treeSanitizer: NodeTreeSanitizer.trusted); <<<<<<<< ERROR
}
Looking at appendHtml, I can see treeSanitizer is an optional param, so that syntax looks fine. In the abstract class NodeTreeSanitizer, I can see: static const trusted = const _TrustedHtmlTreeSanitizer();, so that seems to be fine as well.
Any idea what could be causing this error?
I've logged a bug here in the meantime: https://github.com/rikulo/bootjack-datepicker/issues/2
Looks like your Dartium version is outdated.
Please compare the output of dart --version (command line) and the Dart version on the about://version page in Dartium.

Using the Calendar component in Extjs 7.0 we noticed that the header cells didn't line up correctly with their columns if the language was set to Dutch:
When checking the source code I found the place where these values are added in the cell html;
In Ext.calendar.header.Base, in the setHeaderText function the following code exists:
var me = this,
D = Ext.Date,
value = me.getValue(),
format = me.getFormat(),
domFormat = me.domFormat,
cells = me.cells,
len = cells.length,
useDates = me.useDates,
cell, i;
if (!value) {
return;
}
value = D.clone(value);
for (i = 0; i < len; ++i) {
cell = cells[i];
if (useDates) {
cell.setAttribute('data-date', D.format(value, domFormat));
}
cell.setAttribute('data-day', value.getDay());
cell.innerHTML = D.format(value, format);
value = D.add(value, D.DAY, 1);
}
The innerHtml is set by formatting the Date(D) object which results in the 3 characters of that day. If you change this to just setting a 4 char value like cell.innerHTML = 'Test' the headers line up just fine:
But for some reason this doesn't work when using the D.format value. If somebody has any idea what causes this, I would love to hear.
I can't seem to test if this also goes wrong in another language cause for some reason my packages can't be loaded in anymore.
You can set(or fix) localization override localization constants.
Calendar use Ext.Date.dayNames and Ext.Date.getShortDayName().
All constants list you can see in localization package.
Fiddle example
when I am initializing array globally (outside the method) its working fine. but when I am initializing the same array inside the method its throwing error unexpected token. you can see into code for location of array. this is array calculateResult[] = [];
Screenshot of the error
private log: string ='result';
private kw: string = 'kw';
private frame: number = 0;
public finalResult[] = [];
//here this array is working fine
calculateResult[] = [];
DisplayResult(){
//if i initialize this array here, it's throwing error
// calculateResult[] = [];
if(some_conditions_true){
alert();
this.log = '1SE0 070-2NC70' '\n';
this.kw = '.37' '\n';
this.frame = '71' '\n';
this.calculateResult[0] = this.log;
this.calculateResult[1] = this.kw;
this.calculateResult[2] = this.frame;
this.finalResult.push(this.calculateResult);
for(i=0;i < this.finalResult.length;i++){
console.log(this.finalResult[0][0]);
console.log(this.finalResult[0][1]);
}
}
The first declaration is considered as a class property, so it's correct.
The second one, is incorrect because it is inside the class method and thus should be either declared as
let calculateResult=[];
if you intend to declare a new array of that name,
either addressed as the class property declared above as
this.calculateResult = ...
So keep the first one: calculateResult = [];
If you keep it commented, this.calculateResult[0] will be undefined in the class method, you cannot refer to it.
You should initialize as
DisplayResult(){
this.calculateResult = [];
}

// Public symbol.
f = _eval('(x) => x.$unwrapped', null);

// Private symbol.
var withoutKey = unwrapped.substring(0, atPosition);
var privateKey = unwrapped.substring(atPosition);
f = _eval('(x) => x.$withoutKey', privateKey);
}
// ..... Skipped

V(Mirrors_evalInLibraryWithPrivateKey, 2) \
P.S.
I ask question here becuase I cannot ask it at Dart mail lists.
P.S.
As we can see it static private method in mirrors_impl.dart:
static _eval(expression, privateKey) native "Mirrors_evalInLibraryWithPrivateKey";
Does anyone want that this method should be public? (this is not a question but just a thought aloud).
According to the Dart FAQ a pure string eval like that is not likely to make it into the language, even though other dynamic features will likely be added:
So, for example, Dart isn’t likely to support evaluating a string as
code in the current context, but it may support loading that code
dynamically into a new isolate. Dart isn’t likely to support adding
fields to a value, but it may (through a mirror system) support adding
fields to a class, and you can effectively add methods using
noSuchMethod(). Using these features will have a runtime cost; it’s
important to us to minimize the cost for programs that don’t use them.
This area is still under development, so we welcome your thoughts on
what you need from runtime dynamism.
Ok, I've got a weird one here. I'm trying to make a basic tile engine using a windows form, but some of my code is just...not happening. I'll post the chunks in question.
private void MapEditor_Load(object sender, EventArgs e)
{
LoadImageList();
FixScrollBarScales();
cboCodeValues.Items.Clear();
cboCodeValues.Items.Add("ENEMY");
cboCodeValues.Items.Add("CHEST");
cboCodeValues.Items.Add("NPC");
for (int x = 0; x < 100; x++)
cboMapNumber.Items.Add(x.ToString().PadLeft(3, '0'));
cboMapNumber.SelectedIndex = 0;
TileMap.EditorMode = true;
backgroundToolStripMenuItem.Checked = true;
}
This should be called when the form loads, right? The code dives into LoadImageList(), which contains:
private void LoadImageList()
{
string filepath = Application.StartupPath +
#"\Content\Textures\IndoorTileSet.png";
Bitmap tileSheet = new Bitmap(filepath);
int tilecount = 0;
for(int y = 0; y < tileSheet.Height / TileMap.TileHeight; y++)
{
for(int x = 0; x < tileSheet.Width / TileMap.TileWidth; x++)
{
Bitmap newBitmap = tileSheet.Clone(
new System.Drawing.Rectangle(
x * TileMap.TileWidth,
y * TileMap.TileHeight,
TileMap.TileWidth,
TileMap.TileHeight),
System.Drawing.Imaging.PixelFormat.DontCare);
imgListTiles.Images.Add(newBitmap);
string itemName = "";
if(tilecount == 0)
itemName = "Empty";
if(tilecount == 1)
itemName = "Floor";
listTiles.Items.Add(new ListViewItem(itemName, tilecount++));
}
}
}
The bitmap loads correctly, but then the entire MapEditor_Load method just stops working. tileCount seems to be a local variable in the debugger, and its value is 0, but the debugger never executes the breakpoint on the line which it is assigned. I have absolutely no idea why it would do this, and it's driving me nuts. Any help?
Oh, I put the bitmap load in a try/catch block just to see if it was handling an exception in a weird way, but I had no luck. It's not throwing an exception. I began having this problem immediately after replacing my IndoorTileSet with an updated version. I've tried a clean rebuild, with no success.
I read something about a person having a similar problem, who wound up having to declare something as an Instance of a class, but the post wasn't detailed enough for me to know if that's where I'm going wrong, or what I might have to declare as an Instance for it to work...or what an Instance even means, really.
I'm not sure about the code in LoadImageList() method but I suggest you to use BackgroundWorker or Control.Invoke to make your application more responsive.
Try this :
Bitmap tileSheet = (Bitmap)Bitmap.FromFile(filepath);
The problem is, superficially, that my Bitmap code is throwing an FileNotFound exception, which means I've got a bad filepath. I can handle that. The issue of the program not actually throwing exceptions, and seeming to ignore code, is an issue with 64-bit operating systems not being able to handle exception calls in all instances. The details, and a link to a hotfix to solve the issue, can be found at this site.
I have an array which is filled with platforms that are supposed to move.
var MovingPlatformArray:Array = new Array();
for (var c:int = numChildren - 1; c >= 0; c--){
var child3:DisplayObject = getChildAt(c);
if (child3.name == "movingplatform"){
MovingPlatformArray.push(child3);
}
}
this.addEventListener(Event.ENTER_FRAME,ctrl_birdie);
function ctrl_birdie(e:Event):void{
for(var c in MovingPlatformArray){
MovingPlatform[c].y += speed;
if(MovingPlatformArray[c].hitTestPoint(birdie.x,birdie.y,true)){
birdtelleryvertrager=0;
birdtellery = 0;
birdie.y-=14;
}
if(movingplatform.y <= 25){
speed = 2;
}
if(movingplatform.y >= 350){
speed = -2;
}
}
Right now I have 2 moving platforms in this array. But only one moves up and down. But they both register a touch with the birdie. Am I doing something wrong?
In your listener, you're only setting the position of one platform, which ever one "movingplatform" is a reference to. As all your stage instances of moving platforms are named "movingplatform", one lucky platform is getting referenced by name (the rest ignored), instead of what you intended, which is to use the references in your array and adjust each platform.
You probably meant for movingplatform to be a local variable in your event handler, declared something like this:
var movingplatform:DisplayObject = MovingPlatformArray[c] as DisplayObject;
I'd recommend using a for each loop in place of the for in, because I think it's a little cleaner, but this is a minor style thing:
for each (var platform:DisplayObject in MovingPlatformArray)
{
platform.y += speed;
... rest of your code ...
}
For the sake of clarity, I edited the loop variable to be platform instead of movingplatform, to avoid confusion of having a local variable shadow a stage instance (i.e. this.movingplatform). I wanted it to be clear that the stage instance name is not being used here, because the unintentional instance name reference in your code is the source of your problem in the first place.
As far as i'm concerned, you have two options. use a for each, as adam smith suggested or use a for-loop as it was intended to be used :)
for(var c:uint = 0; c < MovingPlatformArray.length; c++){...
and btw: should "MovingPlatform[c].y += speed;" not be "MovingPlatformArray[c].y += speed;"?
edit: looking at your code, i would also suggest you use MovingPlatformArray[c].hitTestObject(birdie) instead of MovingPlatformArray[c].hitTestPoint(birdie.x,birdie.y,true)
If I were you, I would bring the logic for the platform out, and store it in a class. (Ideally you would do this for the birdie object as well). I have created an example below. The movieclips on the stage should extend Platform rather than MovieClip so they invoke the methods at the bottom.
// Use vectors if you know all the items are going to be the same type
var platforms:Vector.<Platform> = new <Platform>[];
for (var c:int = numChildren - 1; c >= 0; c--){
var child:DisplayObject = getChildAt(c);
// You shouldn't check against names (as per the original post). Because
// names should be unique
if (child is Platform){
platforms.push(child);
// This could be random so each platform has a different range
// This means platform 1 could go from y 30 to y 400, platform 2
// could go from y 60 to y 200, etc
child.setRange(25, 400);
}
}
this.addEventListener(Event.ENTER_FRAME, gameLoop);
// Have an overall game loop
function gameLoop(e:Event):void {
// Loop over the platforms
platforms.forEach(function(item:Platform, i:int, a:Vector.<Platform>):void {
// Hit test function in the class means you only have to pass in one mc
// rather than the points and a boolean
if(item.hitTest(birdie)) {
birdtelleryvertrager=0;
birdtellery = 0;
birdie.y-=14;
}
// Removed the movement logic, this should be kept out of the game loop
// plus how much better does this read?
item.move();
});
}
Then in a class location somewhere, like in a folder game/activeObjects
// A class for the platform stored else where
package game.activeObjects
{
import flash.display.MovieClip;
/**
*
*/
public class Platform extends MovieClip {
private const SPEED:Number = 2;
private var _direction:int = 1;
private var _minimumHeight:Number = 25;
private var _maximumHeight:Number = 350;
public function Platform() {
}
public function setRange(minimumHeight:Number, maximumHeight:Number) {
_minimumHeight = minimumHeight;
_maximumHeight = maximumHeight;
}
public function move():void {
this.y += SPEED * _direction;
if(this.y <= _minimumHeight) {
_direction = 1;
} else if(this.y >= _maximumHeight) {
_direction = -1;
}
}
public function hitTest(mc:MovieClip):Boolean {
return hitTestPoint(mc.x,mc.y,true);
}
}
}
