Yaytay updated CXF-5449:
------------------------
Description:
I have a JPA entity model that has the following chain of relationships:
Order_JpaImpl {
@OneToMany(mappedBy = "order", fetch = FetchType.EAGER, cascade =
{CascadeType.ALL})
List< OrderLine_JpaImpl> orderLines = new LinkedList<>();
}
OrderLine_JpaImpl {
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "prdId", nullable = false)
@ForeignKey
@Index
private Product_JpaImpl orderLineItem;
}
Product_JpaImpl {
@ManyToOne( cascade = {}, targetEntity = Show_JpaImpl.class, fetch =
FetchType.EAGER )
@JoinColumn( name="shwId", nullable = false )
@ForeignKey
@Index
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:

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.
