a4j:commandButton not binding to backing bean

anand_lgv Feb 27, 2013 7:07 PM

Hi,

I am developing a sample JSF 2.0[MyFaces2.0] application with one xhtml page and backing bean. Server : JBoss6, Java version : 1.6. My problem is, i have an a4j:commandButton in xhtml and it is binded to backing bean method. After deploying the application in server if i open the page it says it couldn't find that function[Property] in backing bean. Whereas if we replace the a4j:commandButton with h:commandButton it is working properly. I am using annotations instead of entry in faces-config. Please help me identifying the problem.
