Hi,

I am having the same problem. Did you solve this issue?

Thanks,

In Response To: 

Hey,

I have a simple entityList class inherited from EntityQuery,

Everything seems to work fine with pagination, search ,etc... as seamGen generates this just fine,


but I can't seems to find a way to add a search parameter that is an entity and not a primitive datatype,


so here's an example..
lets assume I have a list of person where each person entity has a reference to an 'address' entity.


  | public class PersonList extends EntityQuery {
  | private static final String[] RESTRICTIONS = {
  | "person.address = #{personList.person.address}"};
  | 
  | private Person = new Person();
  | 
  | ...getting of Person...
  | ...etc...
  | 



In my personList.xhtml I have a default datatable that iterates over the resultList of the 'personList', etc...

and a search parameter as:

  | <h:selectOneMenu id="address" value="#{personList.person.address}" required="false">
  | <s:selectItems value="#{allAddresses}" var="r" label="#{r.displayName}" 
  | <s:convertEntity />
  | </h:selectOneMenu>
  | 

(where 'allAddresses' is a resultList of another entityQuery)


last thing is the parameters, I've added the following parameter to the page descriptor:

  | <param name="address" value="#{personList.person.address}"/>
  | 



Submitting the form results an 'IllegalArgumentException - argument type mismatch'


Am I doing something wrong?
