Description

inputSuggestAjax doesn't work since the phase listener never gets called. The APPLY_REQUEST_VALUES phase is not entered in some circumstances, specifically if the RENDER_RESPONSE view completes early as it does when the view root is null in the following LifecycleImpl code snippet:

//boolean viewCreated = false;
UIViewRoot viewRoot = viewHandler.restoreView(facesContext, viewId);
if (viewRoot == null)

{ viewRoot = viewHandler.createView(facesContext, viewId); viewRoot.setViewId(viewId); facesContext.renderResponse(); //viewCreated = true; }

If the null view root case is entered, the lifecycle is short-circuited and the APPLY_REQUEST_VALUES phase is never entered, causing the ajax control to have no suggested values.

I was able to get the application to work as expected by subclassing the default AjaxDecodePhaseListener as follows:

/**

• Override the default ajax support, since it doesn't seem to work in the
• APPLY_REQUEST_VALUES phase, since that phase never gets entered. Process immediately
• after the RESTORE_VIEW phase instead.
  */
  public class AjaxDecodePhaseListener
  extends org.apache.myfaces.custom.ajax.api.AjaxDecodePhaseListener
  {

public PhaseId getPhaseId()

{ return PhaseId.RESTORE_VIEW; }

public void afterPhase(PhaseEvent event)

{ super.beforePhase(event); }

public void beforePhase(PhaseEvent event) {
}
}
