inputSuggestAjax doesn't work due to phase listener issue.
----------------------------------------------------------
Key: TOMAHAWK-793
URL: http://issues.apache.org/jira/browse/TOMAHAWK-793
Project: MyFaces Tomahawk
Issue Type: Bug
Components: AJAX Form Components
Affects Versions: 1.1.4-SNAPSHOT, 1.1.5-SNAPSHOT
Reporter: David Green
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
{
private static final long serialVersionUID = 1660766611978163100L;
public PhaseId getPhaseId()
{
return PhaseId.RESTORE_VIEW;
}
public void afterPhase(PhaseEvent event) {
super.beforePhase(event);
}
public void beforePhase(PhaseEvent event) {
}
}
