Can't get all values from web page - jsf-2

Question

I am working with JSF 2 and Hibernate. I have XHTML page where bean is get from database and inserted into page. When I change the values of bean and submit for savign I am getting only the last value. What I making wrong?
Here is my XHTML page form code:
<h:form id="edit-slide-form">
<h:panelGrid columns="2">
<h:outputText value="#{msgs.slideTitle}" styleClass="label"/>
<h:inputText id="title" value="#{sliderAction.newSlide.title}" name="#{sliderAction.slide.title}" required="true"/>
<p></p><h:message for="title" errorClass="error"/>
<h:outputText value="#{msgs.description}" styleClass="label"/>
<h:inputTextarea id="description" value="#{sliderAction.newSlide.description}" name="#{sliderAction.slide.description}" required="true"/>
<p></p><h:message for="description" errorClass="error"/>
<p></p>
<h:commandButton value="#{msgs.save}" action="#{sliderAction.saveChanges}" styleClass="button"/>
<h:message for="edit-slide-form"/>
</h:panelGrid>
</h:form>
When I submit this form I can get only last value (e.g id="description").

Also I have notices this warning message:
[org.hibernate.ejb.internal.EntityManagerFactoryRegistry] (http-localhost-127.0.0.1-8080-1) HHH000436: Entity manager factory name (iaau) is already registered. If entity manager will be clustered or passivated, specify a unique value for property 'hibernate.ejb.entitymanager_factory_name'
can this cause such problems
