I have a JPA entity, which hibernate is proxying.
The following action works as it explicitly states the properties to
include, however what I would much rather do is use excludeProperties to
remove the problematic property. The problem property when serialized
causes a "Positioned Update not supported" exception.
The interesting thing is, all the properties on the entity class are
persisted correctly if explicitly included.
Looking in the the debugger shows there is a property called
"$JAVASSIST_READ_WRITE_HANDLER" of type FieldInterceptorImpl which
Hibernate/JPA adds to the entity. I'm pretty sure this is what is
causing it to fail.
I've tried the following:
@Action(value = "list-clients", results = {
@Result(type = "json", params = {
"excludeProperties",
"list\\[.*\\]\\.\\$JAVASSIST_READ_WRITE_HANDLER.*"
})
})
but with no luck. Following is my action and the entity class.
Here is my action (In a _working_ state):
/////////////////////////////
@ParentPackage("json-default")
@Result(type = "json")
public class ListTable extends ActionSupport {
@EJB
private ClientService clientService;
private List list;
@Action(value = "list-clients", results = {
@Result(type = "json", params = {
"includeProperties",
"list\\[.*\\]\\.name, list\\[.*\\]\\.id, list\\[.*\\]\
\.timelogCollection\\..*"
})
})
public String listClients() {
list = clientService.list();
return SUCCESS;
}
public List getList() {
return list;
}
}
/////////////////////////////
Here is the entity:
/////////////////////////////
