}
};
dataContainer.add(testListView);
Form uploadForm = new Form("uploadform",new

System.out.println("******

}
};
uploadForm.add(new TextArea("fileNotes"));
uploadForm.add(new TextField("fileInput"));

}
private class TestTO implements Serializable{
private static final long serialVersionUID = 1L;
private String fileID;
private String fileNotes;
private String fileInput;
public TestTO(){}
public String getFileID() {
return fileID;
}
public void setFileID(String fileID) {

}

}
}
}
and the html code：
<?xml version="1.0" encoding="UTF-8"?>
File
Note
File
Notes
Del
(file)
(notes)
img/delete.gif
*******************
when execute the code, the console show:
****** Input:1
Now size a:0
Now Size b:1
to.getFileInput(0:1
****** Input:2
Now size a:1
First value:2
Now Size b:2
to.getFileInput(0:2
to.getFileInput(0:2
I first input 1 and then input 2 ,but the two value all become 2,why? Could
