シーム 2.2.2、JSF 1.2。それはとても単純に聞こえます:dataTable
各行には、いくつかのボタンが呼び出されたときに観察したいチェックボックスがあります。私はコントローラーを持っています:
@Name("MyController")
@Scope(ScopeType.PAGE)
public class MyController {
private List<MyItem> myItems;
public MyItem[] getItemsList(boolean excluded) {
return myItems;
}
私はMyItem
タイプを持っています:
public class MyItem {
private boolean selected = false;
public boolean isSelected() {
return selected;
}
public void setSelected(boolean selected) {
System.out.println("setting to " + selected);
this.selected = selected;
}
... other things ...
}
これは私のXHTMLです:
<a:form id="formExcludedList">
<rich:dataTable id="excludeList"
value="#{MyController.getItemsList(true)}" var="o">
<rich:column>
<h:selectBooleanCheckbox id="selectComponent"
value="#{o.selected}" />
</rich:column>
チェックボックスをクリックした場合MyItem.setSelected
は実行されません。私はいくつかのファンキーなロギングを取得しています:(簡潔にするために手入れされています)
