JSF SessionScoped Property not set

Question

I'm using a SessionScoped bean for storing my Client object that i retreive from a ClientService thats using JPA. When my webpage is loaded i pass a GET Id parameter for retreiving the correct Client object. Everything goes fine but when i try too edit the Client object properties, it doesn't change for some reason.

Here is my code:

La solution

Edited form values do not get submitted on an Ajax enabled commandButton unless they are explicity named in the execute attribute. Try adding this:

<h:commandButton  value="Change" >
  <f:ajax execute="@form" render="@form" listener="#{editClientBean.edit}" />
</h:commandButton>

The @form is a reserved keyword in the execute and render properties to instruct an Ajax form submission to include the form naming container and all children within that form. You are specifying to submit all form values to be applied to the model and then in the render attribute you are instructing to re render all of the form elements after server side processing.
