Hi everyone,
1、to Werner, i hates it too, i dont like use update, its not a universal
solution.
2、to Jakob, h:messages is a solution, i used to use it. but when you want to
show some message dialog, you have to add things in very page, even in every
form. very ugly.
my solution is hack the sourcecode, hehe.
Java Side:
org.apache.myfaces.context.servlet.PartialViewContextImpl{
....
private void processPartialRendering(UIViewRoot viewRoot, PhaseId phaseId){
List<FacesMessage> messages = _facesContext.getMessageList();
Integer messageSize = 0;
StringBuffer sb = new StringBuffer();
if(messages != null){
messageSize = messages.size();
for(FacesMessage m : messages){
if(m.isRendered())
continue;
sb.append("<message
severity=\"").append(m.getSeverity().getOrdinal()).append("\"><![CDATA[").append(m.getSummary()).append("]]></message>");
m.rendered();
}
}
writer.append("<update id=\"javax.faces.MessageState\"
size=\"").append(messageSize.toString()).append("\">").append(sb).append("</update>");
}
...
}
also jsf.js
myfaces._impl.xhrCore._AjaxResponse.prototype.processUpdate{
...
}else if (node.getAttribute("id") == "javax.faces.MessageState") {
if(node.getAttribute("size") != "0"){
var m = [];
var mn = node.childNodes;
for(var i = 0 ; i < mn.length ; i ++ ){
if(mn[i].tagName == 'message'){
m[m.length]=
{message:mn[i].textContent, severity:mn[i].getAttribute("severity")};
}
}
request.responseMessages = m;
request.responseMessageSize =
node.getAttribute("size");
}
} else {
var cDataBlock = myfaces._impl._util._Utils.concatCDATABlocks(node);
....
}
myfaces._impl.core._jsfImpl.prototype.sendError {
......
eventData.source = context.source;
eventData.responseXML = request.responseXML;
eventData.responseText = request.responseText;
eventData.responseCode = request.status
eventData.responseMessages = request.responseMessages;
eventData.responseMessageSize = request.responseMessageSize;
...
}
myfaces._impl.core._jsfImpl.prototype.sendEvent{
eventData.responseXML = request.responseXML;
eventData.responseText = request.responseText;
eventData.responseCode = request.status
eventData.responseMessages = request.responseMessages;
eventData.responseMessageSize = request.responseMessageSize;
}
I think you will not like it, but its a final solution to me.
anyway, the specification should give a solution about delivery messages in
ajax via jsf.ajax.request.
