Werner Punz commented on MYFACES-2640:
--------------------------------------
Also the question is, does Mojarra handle this usecase or does it not. I will run some tests
the following days, expect a fix by the end of the week one way or the other.
In the meantime please use the workaround of wrapping your entire output into a single node
or just update a complete region which has the component embedded instead.

> (JSF.js) Ajax Render component problem, replace with whole fragment not one element.
> ------------------------------------------------------------------------------------
>
> Key: MYFACES-2640
> URL: https://issues.apache.org/jira/browse/MYFACES-2640
> Project: MyFaces Core
> Issue Type: Bug
> Components: JSR-314
> Affects Versions: 2.0.0-beta-3
> Environment: tomcat 6.0.20 java (mac os x )
> Reporter: Mark Li
> Original Estimate: 4h
> Remaining Estimate: 4h
>
> after ajax submit, jsf.js will re-render some element depending on jsf.ajax.request({render:"
some elements "});
> but this js code will cause some problem.
> jsf.js:
> myfaces._impl._util._Utils.replaceHtmlItem = function (request, context, itemIdToReplace,
newTag, form) {
> ......
> var fragment = range.createContextualFragment(newTag);
> evalNode = item.parentNode.replaceChild(fragment, item)
> .....
> }
> sometime fragment will has more than one childNodes, or the childNode not has clientId,
but the childNode of childNode has clientId.
> this will cause html unstable.
> Please fix it.
> this is my suggestion:
> myfaces._impl._util._Utils.replaceHtmlItem = function (request, context, itemIdToReplace,
newTag, form) {
> .............
> Orginal:
> var fragment = range.createContextualFragment(newTag);
> evalNode = item.parentNode.replaceChild(fragment, item)
> fix:
> var fragment = range.createContextualFragment(newTag);
> var replaceItem = myfaces._impl._util._Utils.findHtmlItemFromFragment(fragment,
itemIdToReplace);
> if(replaceItem == null)replaceItem = fragment;
> evalNode = item.parentNode.replaceChild(replaceItem, item)
> ..................
> }
> myfaces._impl._util._Utils.findHtmlItemFromFragment = function(fragment, itemId){
> if(fragment.childNodes == null)
> return null;
> for(var i = 0; i < fragment.childNodes.length ; i++ ){
> var c = fragment.childNodes[i];
> if(c.id == itemId)
> return c;
> }
> for(var i = 0; i < fragment.childNodes.length ; i++ ){
> var c = fragment.childNodes[i];
> var item = myfaces._impl._util._Utils.findHtmlItemFromFragment(c, itemId);
> if(item != null)
> return item;
> }
> return null;
> };
