Pedro Santos resolved WICKET-3583.
----------------------------------
Resolution: Cannot Reproduce
> java.lang.ArrayStoreException with AttributeModifier
> ----------------------------------------------------
>
> Key: WICKET-3583
> URL: https://issues.apache.org/jira/browse/WICKET-3583
> Project: Wicket
> Issue Type: Bug
> Components: wicket-core
> Affects Versions: 1.5-RC2
> Environment: Windows 7, x86-64, Java 6u24
> Reporter: Alex Rambau
> Labels: wicket
>
> Receiving the following error:
> java.lang.ArrayStoreException: org.apache.wicket.AttributeModifier
> at
> com.wagnerequipment.it.web.applications.portalmanagement.CompanySelectionPage$2.populateItem(CompanySelectionPage.java:68)
> at
> org.apache.wicket.markup.repeater.RefreshingView$1.newItem(RefreshingView.java:113)...
> when executing code (adding the AttributeModifier to the item) that worked
> previously under 1.4:
> DataView<AccountCompany> dataView = new
> DataView<AccountCompany>("pageable", new
> AccountCompanyListDataProvider(filterCharacterInput)) {
> @Override
> protected void populateItem(final Item<AccountCompany> item) {
> AccountCompany company = item.getModelObject();
> item.add(new ActionPanel("actions", item.getModel()));
> item.add(new Label("companyId",
> String.valueOf(company.getCompanyId())));
> item.add(new Label("companyName", company.getCompanyName()));
>
> item.add(new AttributeModifier("class", true, new
> AbstractReadOnlyModel<String>() {
> @Override
> public String getObject() {
> return (item.getIndex() % 2 == 1) ? "even" : "odd";
> }
> }));
> }
> };
> Removing the addition of AttributeModifier to the item causes the issue to go
> away.
