Question

当选择ColorDataGrid中的某个“开发人员行”框时，会发生此错误，该框又调用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，并且我知道已知的bug，其解决方法（添加跟踪语句）在这种情况下并没有真正帮助。我怀疑当我添加对象添加到ArrayCollection时发生溢出但我真的不知道为什么。

必须有某种递归会导致溢出，我错过了什么？

这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

之后添加一个空的trace语句来解决问题

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

这不是解决方案，只是一种解决方法。
