Body
The main problem is that you have two User objects: <ul> <li>User u - currently selected user. </li> <li>User user - just a ManagedBean, most probably with no state (no id, no name, no address).</li> </ul> When performing the edit operation you try to use u.id and user.name, user.address, etc. What you need to do, is to take all the values from the u object. There are many different approaches (I've never used the third one, but it should work and it's the closest to what you've already have): A1. You can keep currently selected object in your UserBean and set it with setPropertyActionListener: <pre><code><f:setPropertyActionListener target="#{userBean.selectedUser}" value="#{u}" /> </code></pre> Then you can call the edit method implemented in the same bean (it has full access to selectedUser object and it can implement the edit itself of just delegate the action to object with edit method implementation). A2. You can place your edit method in the UserBean and pass entire User object as a parameter: <pre><code><h:commandButton value="Save" action="#{userBean.editData(u)}" /> </code></pre> A3. Or you can just call: <pre><code><h:commandButton value="Save" action="#{u.editData()}" /> </code></pre> instead of: <pre><code><h:commandButton value="Save" action="#{user.editData(u.userID)}" /> </code></pre>

1. COThanks a lot, i have tried all three of your suggestion but i am still only getting nulls put into the database, could it be because when i input the data into the data table click of the cell it reverts back to what was there before and thus passing a null value ?

2. COThat'd be it. How about implementing the rowEdit/cellEdit events (just like in the PrimefacesShowcase)? RowEdit example seams pretty much like what you're trying to achieve.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
