    <p>I have a jsp page where I'm trying to send multiple (two currently) ajax requests at once, but I only seem to get the second response. <a href="http://www.coderanch.com/t/121613/HTML-JavaScript/simultaneous-ajax-requests" rel="nofollow">This</a> guy described my problem exactly, but his solution didn't work for me.</p> <p>Here is my js code:</p> <pre><code> function createRequestObject(){ var req; if(window.XMLHttpRequest){ //For Firefox, Safari, Opera req = new XMLHttpRequest(); } else if(window.ActiveXObject){ req = new ActiveXObject("Microsoft.XMLHTTP"); } else{ //Error for an old browser alert('Browser error'); } return req; } function sendRequest(method, url, d){ var http = createRequestObject(); var div = d; if(method == 'get' || method == 'GET'){ http.open(method, url, true); http.onreadystatechange = function() { if(http.readyState == 4 && http.status == 200){ var response = http.responseText; if(response){ document.getElementById(div).innerHTML = response; } } }; http.send(null); } } </code></pre> <p>And here is how I call that code:</p> <pre><code>QC1 Status: &lt;div id='qc1'&gt;blah&lt;/div&gt; &lt;br /&gt;UAT2 Status: &lt;div id='uat2'&gt;blah2&lt;/div&gt; &lt;a onclick="sendRequest('GET','index.jsp?qc1.properties=true','qc1'); " href="#"&gt;qc1&lt;/a&gt; &lt;a onclick="sendRequest('GET','index.jsp?uat2.properties=true','uat2'); " href="#"&gt;uat2&lt;/a&gt; &lt;a onclick="sendRequest('GET','index.jsp?qc1.properties=true','qc1'); sendRequest('GET','index.jsp?uat2.properties=true','uat2'); " href="#"&gt;both&lt;/a&gt; </code></pre> <p>When I call one at a time they work as expected, but the "both" link only updates with the second request, even though I know it runs the index.jsp code for both.</p> <p>EDIT: Ok, after fixing the obvious mistake that BalusC pointed out, it works. Fixed it in this post too.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
