[jira] Created: (TRINIDAD-1719) ajax xml response is not valid in some cases

ajax xml response is not valid in some cases
--------------------------------------------

                 Key: TRINIDAD-1719
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-1719
             Project: MyFaces Trinidad
          Issue Type: Bug
    Affects Versions: 1.2.13-core 
            Reporter: Xavier Brénuchon


Hello,
There is a probleme with ajax calls in trinidad 1.2.13 (not with 1.2.9).
For exemple : I want use a table with a sortable colomun. When I click on the column header, there is an ajax call.
But the xml response is not valid and the page made a repost.

The xml response is not valid because in my page (not in the table), I have, for exemple, a 'h:outputText' with accented character as value.
Indeed, this 'h:outputText' has written its value in the ajax xml output. (not in a '<fragment>', not in a CDATA section).

There is 2 problems :
 First, this 'h:outputText' should not write to output, because it is not affected by the partial render (this 'h:outputText' is not in the table). (This first problem was present in trinidad 1.2.9)
 Second, even if this accented value is written is the output stream and not in a cdata section, accented characters must be compatible with xml (&#x hexa; for exemple) (This problem is new in trinidad 1.2.13)



I looked at source code and I found where are bugs.

First the h:outputText is not ignored because a method must be uncommented  :
PPRResponseWriter.java, ligne 219 :
  /* Needed in JSF 1.2
  @Override
  public void writeText(Object      text,
                        UIComponent component,
                        String      propertyName) throws IOException
  {
    if (_isInsideTarget() && (text != null))
      super.writeText(text, component, propertyName);
  }
  */

This method must be uncomment, because for h:outputText, there is no test _isInsideTarget.




Second, In DispatchResponseConf.java, ligne 75, the content type is searched in RequestStateMap (a new class from 1.2.13) :
return (String) RequestStateMap.getInstance(context.getExternalContext()).get(__CONTENT_TYPE_KEY);

The problem is that the content type is not inserted in RequestStateMap, but always by the old way (1.2.9) ie request.setAttribut.
So trinidad don't finds content type (here :'text/xml') and uses the default HtmlResponseWriter and not XhtmlResponseWriter (see CoreRenderKit.java line 592)

So we must correct both where the content type is written :
DispatchRenderResponse.java, ligne 45 :
      _request.setAttribute(DispatchResponseConfiguratorImpl.__CONTENT_TYPE_KEY, ct.getContentType());
      
and DispatchServletResponse.java, ligne 49 :
      _request.setAttribute(DispatchResponseConfiguratorImpl.__CONTENT_TYPE_KEY, ct.getContentType());


Replace these two line with :
	RequestStateMap.getInstance(_request).put(__CONTENT_TYPE_KEY, ct.getContentType());
