stanislaw89 opened a new issue #165:
URL: https://github.com/apache/royale-compiler/issues/165
Test case:
```
package {
import mx.collections.ArrayCollection;
import org.apache.royale.test.Assert;
public class WeirdArrayCollectionBugTest {
[Test]
public function working():void {
var wrapper:SomeWrapper = createWrapper();
var arr:Array = [];
var collection:ArrayCollection = wrapper.items;
for each(var item:SomeItem in collection) {
arr.push(item);
trace(item);
}
Assert.assertEquals(2, arr.length);
Assert.assertEquals("a", arr[0].name);
Assert.assertEquals("b", arr[1].name);
}
[Test]
public function bug():void {
var wrapper:SomeWrapper = createWrapper();
var arr:Array = [];
for each(var item:SomeItem in wrapper.items) {
arr.push(item);
trace(item);
}
Assert.assertEquals(2, arr.length);
Assert.assertEquals("a", arr[0].name);
Assert.assertEquals("b", arr[1].name);
}
private static function createWrapper():SomeWrapper {
return new SomeWrapper(new ArrayCollection([new SomeItem("a"), new
SomeItem("b")]));
}
}
}
import mx.collections.ArrayCollection;
class SomeWrapper {
public var items:ArrayCollection;
public function SomeWrapper(items:ArrayCollection) {
this.items = items;
}
}
class SomeItem {
public var name:String;
public function SomeItem(name:String) {
this.name = name;
}
}
```
The first "working()" test works fine but the "bug" test fails with this
output
```
WeirdArrayCollectionBugTest.bug .
2Language.as:254 undefined
Language.as:254 WeirdArrayCollectionBugTest.bug E
Language.as:254 Time: 0.025
Language.as:254 There was 1 failure:
Language.as:254 1 WeirdArrayCollectionBugTest.bug Cannot read property
'name' of undefined
```
The only difference is
```
var collection:ArrayCollection = wrapper.items;
for each(var item:SomeItem in collection) {
```
vs
```
for each(var item:SomeItem in wrapper.items) {
```
For some reason
`for each(var item:SomeItem in wrapper.items) {`
generates JavaScript
`var item = foreachiter1_target[foreachiter1];`
which gives `undefined`
Seems like it was supposed to be
`foreachiter1_target.getProperty(foreachiter1);`
