    Need help with <h:selectOneMenu> and valueChangeListener met

    Arbi Sookazian Master

      Using JBoss 4.0.5 and Seam 1.2.1.GA.

      In the below .xhtml file, the valueChangeListener="#{userRoleSearch.processValueChange}" does not fire the public processValueChange method in my SFSB when the commented <s:div> and </s:div> tags around it are uncommented. It does execute when the tags are commented. In either case, the drop-down is rendered.

      Why does this happen? I experienced the same thing with the <s:fragment> tag. Any help would be greatly appreciated...
