s:selectItems, entity-query, convertEntity stop working

[sztank]

Hello,
When I migrate from seam 1.2 to 2.0 the following code stops to work properly:

View:

..
<s:decorate id="clientDecorate" template="layout/edit.xhtml">
 <ui:define name="label">Client:</ui:define>
 <h:selectOneMenu value="#{contract.client}" required="true">
 <s:selectItems value="#{clients.resultList}" var="c" label="#{c.name}" noSelectionLabel="Not defined"/>
 <s:convertEntity />
 </h:selectOneMenu>
</s:decorate>
..

where "clients" is the entity-query defined in components.xml file:

<framework:entity-query name="clients" ejbql="select b from Client b" />

"contract" is the entity bean.
That work perfectly in seam 1.2. In seam 2.0 it behaves this way:
When the view is rendered the selectOneMenu is always set to "Not defined" even when the contract.client field is set. So for example when I filled the form and select some "client" from selectOneMenu and then post the form the proper value is set to contract.client field. I persist the contract entity to the database. Now when the enother (edit) form is displayed with the contract.client set the label is "Not defined"

I have read some posts that deal with s:selectItems migration problems but still can't solve the problem.
Thanks in advance for any help.

Have a look at http://jira.jboss.org/jira/browse/JBSEAM-1648

Thanks!
That was the reason. I do not have equals method. Now it is working.
BTW in my equals method i will have to check if obj is not null otherwise I have NullPointerException - don't understand why..

public boolean equals(Object obj) {
 if(obj != null) {
 return (this.client == ((Client)obj).getClient());
 }
 else return false;
}
