Comment faire pour extraire des objets à partir de ListView - getItemAtPosition ne fonctionne pas

J'ai un adaptateur personnalisé mis en œuvre pour mon ListView. Comment puis-je extraire des objets à partir d'un élément de liste. Voici comment mon adaptateur personnalisé air:

MyCustomAdapter.java

public class MyCustomAdapter extends ArrayAdapter<DashboardBean> {
Context context;
int layoutResourceId;
DashboardBean currentMRB;
Vector<DashboardBean> data;
public MyCustomAdapter(Context context, int layoutResourceId, Vector<DashboardBean> data) 
{
super(context,layoutResourceId,data);
this.layoutResourceId = layoutResourceId;
this.context=context;
this.data = data;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
MyStringReaderHolder holder;
if(row==null)
{
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent,false);
holder= new MyStringReaderHolder();
holder.project = (TextView)row.findViewById(R.id.project);
holder.workRequest = (TextView)row.findViewById(R.id.work_request);
holder.startDate  = (TextView)row.findViewById(R.id.start_date);
holder.status = (TextView) row.findViewById(R.id.status);
row.setTag(holder);
}
else
{
holder=(MyStringReaderHolder) row.getTag();
}
DashboardBean mrb =data.elementAt(position);
System.out.println("Position="+position);
holder.project.setText(mrb.project);
holder.workRequest.setText(mrb.workRequest);
holder.startDate.setText(mrb.startDate);
holder.status.setText(mrb.status);
return row;
}
static class MyStringReaderHolder {
TextView project, workRequest, startDate, status;
}
}

Voici l'DashboardBean.java

 public class DashboardBean {
public String project;
public String workRequest;
public String startDate;
public String status;   
public DashboardBean(String project,String workRequest,String startDate,String status)
{
this.project = project;
this.workRequest = workRequest;
this.startDate = startDate;
this.status = status;
}
}

Voici fragment de code java à partir d'où j'appelle onClickListener() :

mListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> myAdapter, View myView, 
int myItemInt, long mylng) {
TableRow tableRow = (TableRow) (mListView.getItemAtPosition(myItemInt));
String project = ((TextView) tableRow.findViewById(R.id.project)).getText().toString();
String workRequest = ((TextView) tableRow.findViewById(R.id.work_request)).getText().toString();
String startDate = ((TextView) tableRow.findViewById(R.id.start_date)).getText().toString();
String status = ((TextView) tableRow.findViewById(R.id.status)).getText().toString();
showWorkRequest(project, workRequest, startDate, status);
}
});

Et le code xml:

<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tabRow1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="@style/BodyRow"
android:gravity="center_horizontal" >
<RelativeLayout 
android:id="@+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal" >
<TextView
android:id="@+id/status"
android:layout_width="wrap_content"
style="@style/BodyText"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:textColor="@color/textColor"
android:text="TextView" />
<TextView
android:id="@+id/start_date"
style="@style/HourText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="TextView"  android:textColor="@color/textColor" android:textSize="10sp"/>
<TextView
android:id="@+id/project"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="@+id/start_date"
android:gravity="center_horizontal"
style="@style/LeftHeaderText"
android:text="TextView" android:layout_marginLeft="5dp"
android:textColor="@color/textColor" android:textStyle="bold"/>
<TextView
android:id="@+id/work_request"
android:layout_width="wrap_content"
style="@style/BodyText"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/project"
android:layout_below="@+id/project"
android:text="TextView"
android:textColor="@color/textColor" />
</RelativeLayout>
</TableRow>

Je suppose que je ne peux pas utiliser onClickListener comme il est généralement utilisé parce que je suis extendind adaptateur personnalisé. Dans ce cas, ils peuvent être un problème avec

public void onItemClick(AdapterView<?> myAdapter, View myView, 
int myItemInt, long mylng)

Mais le journal dit: ClassCastException à DashboardBean.

De toute façon, je ne peux pas le fixer. Quelqu'un pourrait-il aider?
