[richfaces-issues] [JBoss JIRA] (RF-12571) aj4:status - onerror - more documentation - more attributes ?

[Jean ANDRE (JIRA)]

     [ https://issues.jboss.org/browse/RF-12571?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jean ANDRE updated RF-12571:
----------------------------

    Description: 
The documentation on aj4:status does not explain very well what we should expected as data to be passed or retrieved when error occurred. 


{code}
<a4j:status id="ajax-status"
            name="ajaxStatus"
            onstart="#{rich:component('messageWaiter')}.show()"
            onstop="#{rich:component('messageWaiter')}.hide()"
            onerror="alert(event.type);alert(status);" />
{code}

Based on this code, it seems we can catch at least one object - the event but the event doesnot seem to have any valuable information.

It is possible to sent us some valuable information when we received the onerror event and tell us what we can use as information to be displayed to user when an ajax error occurred.

Some old versions (?), seems to have 3 attributes like req, status, message on event error but with RichFaces 4.2.3 final, I catch nothinh


from https://community.jboss.org/message/54813
{code}
A4J.AJAX.onError = function(req, status, message){
 if(status == 505 || status == 500 || status == 400){
 window.alert("Error: "+message + "\n Please contact administrator" );
 }
 }
{code}

For example, in this situation, I emulated an error into the controller.


public String doOpenItem(String tabId, Integer itemId) throws InterruptedException {
  Thread.currentThread().join(2000);
  Integer i = null;
  i.doubleValue();
  return "thepage";
}
