Actionscript 3 VerifyError:错误#1023:ArrayCollection的addItem上发生堆栈溢出

选择ColorDataGrid中的一个“开发者行”框时会发生此错误，该框依次调用ExtractProjectPopup.mxml中的updateDeveloper（）方法，如下所示

public function updateDeveloper():void
{
    developerIndexArray:ArrayCollection = new ArrayCollection();
    var devObject:Object = new Object();
    var ObjectString:String = developerIndexArray.toString();
    if(developerGrid.selectedIndex >= 0)
    {
        var developer:ExtractPopUpDeveloperRow = this.developerRows.getItemAt(developerGrid.selectedIndex) as ExtractPopUpDeveloperRow;
        developer.isPartOfProject = ! developer.isPartOfProject;
        if(developer.isPartOfProject)
        {   
        devObject.index = developerGrid.selectedIndex;
        viewResumeButton.visible = true;
        developerIndexArray.addItem(devObject);     
        }
    }
}

我目前正在使用Flex SDK 3.6，我知道已知的解决方案（添加跟踪语句）在这种情况下没有真正的帮助。我怀疑当我将对象添加到ArrayCollection时会发生溢出，但我真的不知道为什么

一定有某种递归迫使溢出，我遗漏了什么吗

以下是导致溢出的堆栈跟踪：

[mpt.project::ExtractProjectPopUp~[O] Object~[A] int[I] int[I]  mpt.vo.extraction::ExtractPopUpDeveloperRow[O] String[S] int[I]]   {mpt.project::ExtractProjectPopUp~[O]} (mx.collections::ArrayCollection[O] int[I])

感谢您的帮助。

奇怪的是，通过在语句后添加一个空跟踪语句，问题得到了解决

var developer:ExtractPopUpDeveloperRow = this.developerRows.getItemAt(developerGrid.selectedIndex) as ExtractPopUpDeveloperRow;

这不是一个解决方案，只是一个变通办法

从堆栈的角度来看，我甚至不认为它能到达

developerIndexArray.addItem

。它似乎是关于

this.developerRows.getItemAt

。还有一个后期绑定，如

astypelate

所述，它可以创建递归，如

72:dup

所示。尽管如此，如果不看看

developerRows

成员和

ExtractPopUpDeveloperRow

类到底是什么，我真的不知道。此外，您的AS3似乎是一个片段（即，它具有神秘变量的不完整性），尽管您没有另外描述。
