p:dialog does not set properties to Entity - jsf

Question

I have the following p:datatable that hold two buttons that call the View and the Add dialogs.
The problem is with the Add dialog, that does not seem to be setting properties to any of the Entity objects.
When I put a break on the save() method inside ChildrenController.java all values a 'null'.
I am using:
PrimeFaces 5.1 |
Mojarra 2.2.7 |
Glassfish 4.1 |

Answer 1

You didn't process your components in your question's code. What you did there to fix the problem in your own answer is including your form in the list of UIComponents to process. That means that JSF will not look at all your input components in your form and that's why it will not retrieve any values you entered in those fields to set them in your backing bean.
To get a better understanding of what process means, you may look at this question.

Answer 2

Solved the problem by putting the p:commandButton inside the p:panelGrid of the dialog which makes absolutely no sense to me whatsovever ! Anyway here is how the dialog looks like:
<h:form id="formName">
<p:dialog>
<p:panelGrid>
<p:commandButton process="#this :formName" ajax="false" actionListener="#{bean.method()}"/>
</p:panelGrid>
</p:dialog>
</h:form>
EDIT: edited code to be more readable
