Primefaces mobile and client side validation doesn't work

[i.kuzmin]

Hello everybody,

I'm developing a mobile web app with Primefaces and want to integrate a client side validation but it doesn't work. It seems that the mobile render kit is not compatible with it or maybe I forgot to do something. Could anyone help me ? Thank you in advance.

The problem is when I use :

<context-param>
<param-name>primefaces.CLIENT_SIDE_VALIDATION</param-name>
<param-value>true</param-value>
</context-param>

AND

<default-render-kit-id>PRIMEFACES_MOBILE</default-render-kit-id>

AND

validateClient="true" attribute,

client side validation script is not called and the page is automatically refreshed after I click the commandButton even if ajax is enabled.

In the web browser I have this java script error once a page is loaded :

validators.js;jsessionid=1409a4a5b3f93be1b8d3134bfcce:1 Uncaught TypeError: Cannot set property 'custom.emailValidator' of undefined
at validators.js;jsessionid=1409a4a5b3f93be1b8d3134bfcce:1

ALL WORKS FINE WITHOUT ANY ERRORS when I remove <default-render-kit-id>PRIMEFACES_MOBILE</default-render-kit-id>

This is my sign_in.xhtml : (for the javascript and EmailValidator I copied example code from the Primefaces Showcase)

I include multiple pm:pages in one page.

</h:form>
</pm:content>

<!--Block fixed to the bottom of the page with New user and Forgot password links-->
