PrimeFaces autoComplete dropdown not showing values

After updating from PrimeFaces 8 to 10 all the autoComplete components in my application do not show values when opening the dropdown menu

enter image description here

The list stays empty. When I debug into AutoComplete and the AutoCompleteRenderer, I can see that the suggestions for an empty query are generated

But later in the AutoCompleteRenderer the AutoComplete is a new instance (with same component id) without any suggestions.

This is my JSF page

        <p:outputLabel value="Selected item: #{testBean.item}" />
    </h:form>
</h:body>
</html>

and my bean

import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;

import org.apache.commons.lang3.StringUtils;

import lombok.Getter;
import lombok.Setter;

@Getter
@Setter
@ManagedBean
@ViewScoped
public class TestBean {

    private String item;

    private final List<String> items = Arrays
            .asList("item-0", "item-1", "item-2", "item-3", "item-4", "item-5", "item-6", "item-7", "item-8", "item-9");

    public List<String> completeItems(final String query) {
        return items.stream()
                .filter(i -> StringUtils.containsIgnoreCase(i, query))
                .collect(Collectors.toList());
    }
}

Any ideas what I am doing wrong?

Solution

  • I found it. javax.faces.PARTIAL_STATE_SAVING was set to false. If I remove this in the web.xml everything works fine. This option was set before I joined the project and I can't find anything explaining why it was set to false.
