私はここに来て、よく似た問題のためにかなりの時間を探しました。 この問題が他の場所で解決されている場合は、私にその答えを教えてください。ありがとう。ArrayIndexOutOfBoundsException動的な列のprimefaces getRowDataから
状況： 私は動的な列を持つDataTableを持っています。 フィルタリングと並べ替え作業。
テーブル内の選択された行を読み込み、選択した行のセル内の値に応じて異なるアクションを実行するコンテキストメニューを実装する必要があります。 行を取得しようとすると java.lang.ArrayIndexOutOfBoundsException がスローされます。
ヘルプとヒントは非常に高く評価されます。
おかげで、 アーサー
列と、コンテキストメニューでのDataTable：

列モデルコード
static public class ColumnModel implements Serializable {
private static final long serialVersionUID = -2504875837397753172L;
private final String header;
private final String property;
private final String align;
private final Integer width;
public ColumnModel(String header, String property, String align, Integer width) {
this.header = header;
this.property = property;
this.align = align;
this.width = width;
}
public String getHeader() {
return header;
}
public String getProperty() {
return property;
}
public Integer getWidth() {
return width;
}
public String getAlign() {
return align;
}
}
列の生成コード：
protected void setDynamicColumns() {
String[] columnKeys = dataController.getTableHeaders();
columns = new ArrayList<>();
for (String columnKey : columnKeys) {
HashMap<String, Object> columnInfo
= dataController.getColumnInfo(layoutName, columnKey);
// Get field names and values from ab_umsatz_layout
Integer width = (Integer) columnInfo.get("FELD_WIDTH");
String align = (String) columnInfo.get("FELD_ALIGN");
ColumnModel columnModel
= new ColumnModel(columnKey.trim().toUpperCase(),
columnKey.trim(), align, width);
columns.add(columnModel);
}
}
onRowSelect方法：
public void onRowSelect(SelectEvent selectEvent) {
DataTable dataTable = (DataTable) selectEvent.getComponent();
try {
Object selectedRow = dataTable.getRowData();
System.out.println(selectedRow);
}
catch (Exception e) {
e.printStackTrace();
}
}
