Pedro Santos commented on WICKET-3583:
--------------------------------------
The problem is at CompanySelectionPage line 68, the program is trying to
assigin an AttributeModifier to an array of other type. How do code look like
in there?
As it is not Wicket code, this error description fits better in user mailing
list.
> 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.
