[jboss-user] Re: SeamGen+EntityQuery - ' argument type mismatch'

See Thread at: http://www.techienuggets.com/Detail?tx=11318 Posted on behalf of a User Hi, I am having the same problem. Did you solve this issue? Thanks, mail:guy.bashan@gmail.com Guy. 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?
