322147 - xmlhttp request returns xhtml with an img tag but does not display the image,

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[bdn]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.7.12) Gecko/20051010 Firefox/1.0.7 (Ubuntu package 1.0.7)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.7.12) Gecko/20051010 Firefox/1.0.7 (Ubuntu package 1.0.7)

A xmlhttp response returns the following xhtml elements (which are then appended to the body of a page) but fails to display the image. A http trace shows a request for the xmlhttp request but no request for the image, as such the alt text is displayed. I have not had this issue under windows IE.

<div xmlns=\"http://www.w3.org/1999/xhtml\"><img id=\"test\" src=\"../themes/default/blockImageHead.png\" alt=\"test\" /></div>

Right clicking the alt text and clicking "view image" then displays the image correctly in a separate window.

Reproducible: Always

Steps to Reproduce:
1. Create a javascript xmlhttp (see below) that calls a url that returns some the xhtml: <div xmlns=\"http://www.w3.org/1999/xhtml\"><img id=\"test\" src=\"../themes/default/blockImageHead.png\" alt=\"test\" /></div>
-- Replace the image with an image you have access to --
2. Create a page that launches the javascript and appends the xhtml to the page.

Javascript function:

    var xmlhttp=false;
    var url='http://localhost:8080/ws/home';    

    if (window.XMLHttpRequest) { 
        xmlhttp = new XMLHttpRequest(); 
    } else if (window.ActiveXObject) {
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); 
    }

    xmlhttp.open("GET", url, false);
    xmlhttp.send(null);

    if (xmlhttp.status != 200) {
        alert (xmlhttp.responseText);
    } else {
        ws = document.getElementById('workspace'); // this is the body
        if (browser.isIE) {
            ws.appendChild(xmlhttp.responseText);
        } else 
        if (browser.isNS) {
            ws.appendChild(xmlhttp.responseXML.childNodes.item(0));
        }

Actual Results:  
See details

Expected Results:  
Image should be displayed. I've tried pre-loading but this does not help:

//        var images = xmlhttp.responseXML.getElementsByTagName("img");
//        if (images.length != 0) {
//            var preLoad = new Array(images.length);
//            for (var i = 0; i < images.length; i++) {
//                var img = images[i];
//                if (img != null) {
//                    preLoad[i] = new Image();
//                   preLoad[i].src = img.src;
//               }
//            }
//              delay(100);
//        }

This could be an issue related to base URIs.  Have you tried using an aboslute URL for the image?

Hi Jesse, 

Yes. I have tried a combination of addresses all of which resolve if directly typed into the browser toolbar. I considered the same possibility and tried the absolute url: "http://localhost:8080/ws/home/imagetest.png". This made no difference. In addition I have taken the dynamic xhtml returned by the server and created a static web page from it and then all images resolve ok.

Does http://www.squarefree.com/bug322147/grab.html work for you?  If not, what are you doing differently?

Hi Jesse,

No. This doesn't work, unless I right-click and select view image.

You're using a very old version of Firefox.  Can you upgrade to Firefox 1.5 (at least) and say whether you still see the bug?

Hi Jesse,

I have upgraded as you have recommended and now "http://www.squarefree.com/bug322147/grab.html" works ok. This has resolved this  bug as well. I also note that drag n drop is much smoother too. Excellent.

Thank you
Brendan
