ArrangeableModel with Errors

[dadidom]

Hi There,

i implemented the ArrangeableModel as shown in the demo application. But i get the following error, while calling the page with the table:

java.lang.ClassCastException: java.lang.Boolean cannot be cast to java.lang.String

    at com.arvato.rewards.sumas.ui.utils.JPADataModel.createFilterCriteria(JPADataModel.java:180)

The Problem is at this poin (last line):

 private Expression<Boolean> createFilterCriteria(CriteriaBuilder criteriaBuilder, Root<T> root)
  {
    Expression<Boolean> filterCriteria = null;
    List<FilterField> filterFields = arrangeableState.getFilterFields();
    if (filterFields != null && !filterFields.isEmpty())
    {
      FacesContext facesContext = FacesContext.getCurrentInstance();

      for (FilterField filterField : filterFields)
      {
        String propertyName = (String) filterField.getFilterExpression().getValue(facesContext.getELContext());

he tries to determined the EL value: "#{property}" which is used in the including "jpaColumn.xhtml".

But the ELContext can't resolve the value for this property! I debugged the application and tested other EL-Values. The "property" and "bean" values from the include-page can't be resolved, all other references (the managedbeans for example) worked well...

Any ideas? Help?

Thanks a lot

Hello, have you resolved it yet? ... I have the same issue .-(

Perhaps I've found the solution(s) but I don't know which one of them is the right:

if you are using maven, try this one: Add Exclusions tag with all exclusions.

{code:xml}
<dependency>
            <groupId>org.richfaces.ui</groupId>
            <artifactId>richfaces-components-ui</artifactId>
            <version>${org.richfaces.bom.version}</version>
            <exclusions>
                <exclusion>
                    <artifactId>jsf-api</artifactId>
                    <groupId>com.sun.faces</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>jsf-impl</artifactId>
                    <groupId>com.sun.faces</groupId>
                </exclusion>
            </exclusions>
        </dependency>
{code}

The second one solution maybe is to change version of RF to 4.1.0.CR2.

In both cases don't forget to clean your project.
