@JordiCastilla, code is same as http://www.primefaces.org/showcase-ext/sections/dynaform/basicUsage.jsf to reduce the question size i haven;t included it in here — Jeevanantham, May 25 '15 at 10:18
Code can't be exactely the same since it does not happen there afaics. And do include it, since the link you refer to might disappear in the future and it will be difficult for others to use this post — Kukeltje, May 25 '15 at 10:43
If you want someone to help you, create an [MCVE](https://stackoverflow.com/help/mcve). You're asking for free help: the least you could do is to make it easier on us. — DavidS, Jul 30 '15 at 17:17

I was having the same problem, and fixed it by adding the id attribute to the form tag to:

<h:form id="mainForm" prependId="false">
  <h:panelGroup id="dynaFormGroup">

---- EDIT -----

When you look at the code posted, you can see that the command button has the fully qualified id of the components in the update attribute :mainForm:dynaFormGroup

<p:commandButton value="Submit" action="#{dynaFormController.submitForm}"
  process="dynaForm" update=":mainForm:dynaFormGroup :mainForm:inputValues"
  oncomplete="handleComplete(xhr, status, args)"/>

That's why the form should have the id="mainform"

On the other hand, why when the id is missing causes the java.lang.StackOverflowError, is something i still don't know. If I found the reason i will update.

A better answer would explain (1) what the problem is and (2) how the proposed solution fixes it. – DavidS Jul 30 '15 at 17:18
explain your answer plz. – Zakaria Acharki Jul 30 '15 at 17:35
Try to make it work without the prependId= false. Using that is bad practice in relation to possible ajax calls – Kukeltje Jul 30 '15 at 21:41
