Problem with using the basic <a4j:support>
Hi,
I am new to Ajax4JSF. I am trying to use the basic tag <a4j:support> in my JSF page and it does not seem to work for me. It does not throw any exception or error. It simply does not replicate the data which it is supposed to do. I have the required Jar files (ajax4jsf-1.1.0.jar and oscache-2.3.2.jar) in my application's lib directory and I also added the tag-lib referencing as below :
<%@ taglib uri="https://ajax4jsf.dev.java.net/ajax" prefix="a4j"%>
Basically I am developing Portal with JSF and MyFaces and my portal/porlets work fine. NO issue with them.
Below are my web.xml and JSF page code wherein you will see that I have added some filter as recommended in the Developers Guide of a4j from your website. These additions in web.xml are marked starting with <!-- AJAX4JSF START HERE --> and
ending with <!-- AJAX4JSF END HERE -->.
