p:ajax feature not working in Liferay portal

Question

I can\'t get the PrimeFaces 6.1 built-in ajax feature to work when using a liferay portal. I\'ve started with the very initial use case example, that is the one shown in the

Answer 1

I've just sorted the problem out. There were 2 problems. The first one (the less serious one) is that the js callbacks are being invoked wrong. The right way to invoke them should be as follows:

<p:ajax process="@form" update="output" onstart="onStart()" oncomplete="onComplete()" onsuccess="onSuccess()" onerror="onError()" />

The serious problem is related to a missing parameter in the liferay-portlet.xml config file. Well, it maybe I should haved started saying that I was dealing with a Liferay portlet containing a JSF portlet which uses Primefaces. It all implies that liferay-portlet.xml config file is required. And this config file has to contain the following parameter:

<requires-namespaced-parameters>false</requires-namespaced-parameters>

The problem is that the default liferay-portlet.xml file, that is, the one that the eclipse IDE wizard creates DOES NOT automatically include such a parameter. After including such a parameter, it all works as expected.

(Down vote for Liferay people working in the Liferay Faces Bridge project).

UPDATE: The way I create the Liferay Plugin Project.

1. New > Project > Liferay Plugin Project

   Plugin Type: portlet

   Include Sample code -> unchecked

   Launch New Portlet Wizard afer project is created -> checked

2. Next > JSF 2.x

3. Next > Primefaces
4. Finish

Steps when Wizard is displayed:

1. Portlet class: javax.portlet.faces.GenericFacesPortlet
2. Next View template: Primefaces
3. Next
4. Finish

Major result after those steps is that file liferay-portlet.xml doesn't have the element:

<requires-namespaced-parameters>false</requires-namespaced-parameters>

Development settings:

• Eclipse Java EE IDE for Web Developers Version: Mars.2 Release (4.5.2) - Build id: 20160218-0600
• Liferay IDE 2.2.4.201507230603-ga5

Any clarification would be appreciated.
