Sebasti?n Fiorentini commented on JBSEAM-1909:
----------------------------------------------

The solution to this is pretty simple, and relies on a minor modification / extension to org.jboss.seam.pageflow.Pageflow. 

package ar.com.sdc.seam;

import javax.faces.context.FacesContext;
import org.jboss.seam.annotations.Install;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.pageflow.Page;
import org.jboss.seam.pageflow.Pageflow;

@Name("org.jboss.seam.pageflow.pageflow")
@Install(value = false, precedence = Install.DEPLOYMENT)
public class PageflowRichFaces extends Pageflow {

	@Override
	protected void navigate(FacesContext context) {
		Page page = getPage();
		String viewIdActual = context.getViewRoot().getViewId();
		String proximo = page.getViewId();
                //the patch is the following line
		if (!viewIdActual.equals(proximo)) {
			if (!page.isRedirect()) {
				render(context, page);
			} else {
				redirect(page);
			}
		}
		setDirty();
	}
}

Also, If you want to use this extension, put this in your components.xml:

	<component name="org.jboss.seam.pageflow.pageflow"
		class="ar.com.sdc.seam.PageflowRichFaces" installed="true" />

Now, on your Pageflow, if you navigate to the same page within the states, it use RichFaces transition, so the page doesn't gets re rendered.

I though that this solution could be pretty incorporated to the next release, and with a simple boolean parameter anyone can turn on or off the comparision behavior (that which decides to re render or not the current page).

Hope this helps.

> When I use ajax4jsf:commandButton calling bean action rerender of components is working fine, but when I call pageflow action entire page is reloaded instead of rerender of particular component
