Hello,

I have an entity bean "CancerType" and a SFSB(long running) "MethSearch" and there is a "search.xhtml".

One of the search fields in "search.xhtml" is a selectOneMenu, in which all CancerTypes are listed. The selected one is set to "cancerType" variable in MethSearch bean. MethSearch bean has a method "find()", which is called from search.xhtml after a CancerType in selectOneMenu selected.

Problem: Before Seam the Method "find" calls, the overriden method "equals(Object otherCancerType)" in CancerType Entity is called, but the parameter "otherCancerType" is null. And i need to find why?

here some codes: first CancerType Entity

@Entity
public class CancerType implements java.io.Serializable {
// id and some string variables
@Override
 public boolean equals(Object otherCancerType) {
 if(this.id == ((CancerType)otherCancerType).getId())
 return true;
 return this.name.equals(((CancerType)otherCancerType).getName());
 }
}

@Stateful
@Name("methsearch")
public class MethSearch implements IMethSearch{
 @PersistenceContext(type=PersistenceContextType.EXTENDED)
 private EntityManager entityManager;
.....
@Begin
 public void find() {
 Criteria criteria = ....
}

<h:outputLabel for="cancerTypeid">Cancer type:</h:outputLabel>
 <h:selectOneMenu id="cancerTypeid" value="#{methsearch.cancerType}">
 <s:selectItems value="#{cancerTypeDAO.getAll()}" var="cancerType" label="#{cancerType.name}"
 noSelectionLabel="Please Select..."/>
 <s:convertEntity />
 </h:selectOneMenu>
....
<h:commandButton value="Find" action="#{methsearch.find()}" />

<page view-id="/search.xhtml">
 <navigation from-action="#{methsearch.find()}">
