所以，我有2個持有人使用CustomLayout。Vaadin，CustomLayout循環和IndexOutOfBound
PersonHolder：
<div class='persons_holder' location='persons_list'></div>
PersonsHolder：
<div class='single_person_holder'>
<div class='person_action' location='person_action'></div>
<div class='person_data'>
<div class='person_name' location='person_name'></div>
<div class='person_shares' location='person_shares'></div>
</div>
</div>
現在，我想用一些對（;;）指令使用它。簡而言之：
CustomLayout personsHolderLayout = new CustomLayout(PERSONSHOLDER);
Panel tmpPanelPersons = new Panel();
for (PersonView personView : personViews) {
Component compToAdd2 = magicWithData(2);
Component compToAdd3 = magicWithData(3);
CustomLayout singlePersonHolderLayout = new CustomLayout(SINGLEPERSONHOLDER);
singlePersonHolderLayout.addComponent(compToAdd2, "person_action");
singlePersonHolderLayout.addComponent(compToAdd3, "person_name");
Panel tmpPanelPerson = new Panel();
for (SingleEntryView chng : ((PersonWithSharesView) personView.getEntries()) {
Component comp2add = magicWithAnotherData(1);
tmpPanelShares.addComponent(comp2add);
singlePersonHolderLayout.addComponent(tmpPanelShares, "person_shares");
}
tmpPanelPersons.addComponent(singlePersonHolderLayout);
}
personsHolderLayout.addComponent(tmpPanelPersons, "persons_list");
經過一個循環，就完成了。我有indexOutOfBound在：
CustomLayout singlePersonHolderLayout = new CustomLayout(SINGLEPERSONHOLDER);
有人能告訴我我做錯了什麼嗎？ 我是Vaadin的新人:)所以請溫柔一點。
