[jira] Updated: (TOMAHAWK-793) inputSuggestAjax doesn't work due to
phase listener issue.
[ http://issues.apache.org/jira/browse/TOMAHAWK-793?page=all ]
David Green updated TOMAHAWK-793:
---------------------------------
Status: Patch Available (was: Open)
> 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) {
> }
> }
