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());
| }
| }
MethSearch SFSB:
@Stateful
| @Name("methsearch")
| public class MethSearch implements IMethSearch{
| @PersistenceContext(type=PersistenceContextType.EXTENDED)
| private EntityManager entityManager;
| .....
| @Begin
| public void find() {
| Criteria criteria = ....
| }
|
search.xthml:
<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()}" />
|
and pages.xml:
<page view-id="/search.xhtml">
| <navigation from-action="#{methsearch.find()}">
| <end-conversation/>
| <redirect/>
| </navigation>
| </page>
Thank you in advance :)
