      I have a JPA entity model that has the following chain of relationships:

      Order_JpaImpl {
      @OneToMany(mappedBy = "order", fetch = FetchType.EAGER, cascade =


      List< OrderLine_JpaImpl> orderLines = new LinkedList<>();

      OrderLine_JpaImpl {
      @ManyToOne(fetch = FetchType.EAGER)
      @JoinColumn(name = "prdId", nullable = false)
      private Product_JpaImpl orderLineItem;

      Product_JpaImpl {
      @ManyToOne( cascade = {}, targetEntity = Show_JpaImpl.class, fetch = FetchType.EAGER )
      @JoinColumn( name="shwId", nullable = false )
      private Show_JpaImpl show;

      Show_JpaImpl {
      @Column( length = 32, unique = true, nullable = false )
      private String shortName;

      I want to use FIQL to get all the orders that include orderlines that have products from a given show.
      So I have a simple search expression: show==AMND
      And a mapping:
      private static Map<String,String> createBeanNameMap()

      { Map<String,String> map = new HashMap<>(); map.put("customerdisplay","customerDisplay"); map.put("ordertime","orderTime"); map.put("fulfilmentstatus","fulfilmentStatus"); map.put("show","orderLines.orderLineItem.show.shortName"); return map; }

      That is used by:
      SearchCondition<ImplType> searchCondition = searchContext.getCondition(targetClass, getBeanNameMap());

      Raises this exception:
      Caused by: java.lang.IllegalArgumentException: argument type mismatch; setter parameter type: java.util.List, set value type: uk.co.spudsoft.spiderweborders.model.jpaimpl.OrderLine_JpaImpl
      at org.apache.cxf.jaxrs.ext.search.Beanspector.setValue(Beanspector.java:152) ~[cxf-rt-rs-extension-search-2.7.8.jar:2.7.8]

      OrderLines is a list of OrderLine objects, but the template is being created with just one and the setter doesn't know how to handle lists.
      I tried adding a setter that takes a single OrderLine, but something got upset when it saw that the getter and setter were of different types.

      I /think/ the failure occurs when you have:
      1. A parent entity containing a list of children.
      2. The children entities contain a single grandchild.
      3. The search is for a property of the grandchild.
      And it fails when it tries to set the grandchild in the child.

      I've actually got another layer in the hierarchy (great-grandchild), but given where the exception comes from I suspect that isn't needed to cause the failure.
