[tehackio]

If one ajax call inside column of org.ajax4jsf.model.ExtendedDataModel to render outside, method walk is called many times;

More information.

I'm using richfaces 4.3.1.Final, apache-tomcat-7.0.34, servlet-weld 1.1.11.

On org.richfaces.component.UIDataAdaptor, context.getFacesContext().getAttributes().get("javax.faces.visit.SKIP_ITERATION") returns "null", therefore "false".

    /**
     * @param context
     */
    private boolean requiresRowIteration(VisitContext context) {
        // The VisitHint.SKIP_ITERATION enum is only available as of JSF 2.1.  Switch to using the enum when we no longer want to support JSF 2.0.
        // return !context.getHints().contains(VisitHint.SKIP_ITERATION);
        return ! Boolean.TRUE.equals(context.getFacesContext().getAttributes().get("javax.faces.visit.SKIP_ITERATION"));
    }
