    <p>I came across a strange problem . I have a jsp , which is calling an iframe . The iframe gets loaded with data from java.</p> <p>Now to render the iframe i am using customized <a href="http://code.google.com/p/infoscoop/source/browse/trunk/src/main/web/js/lib/control.modal.js?r=370" rel="nofollow">control-modal.js</a>.</p> <p>Now my iframe is coded after li tag like this :</p> <pre><code>&lt;li&gt; &lt;a id="modalLink" href="#myModal"&gt;Set up my Modal&lt;/a&gt; &lt;/li&gt; &lt;div id="myModal" &gt; &lt;div class="modalsubcol"&gt; &lt;p class="close"&gt;&lt;a href="#"&gt;&lt;img src="/.../close-button.gif" alt="Close"/&gt;&lt;/a&gt;&lt;/p&gt; &lt;iframe id="modal-frame"style="display:none;" height="430" width="675" src="&lt;%= getTheModal()%&gt;"&gt;&lt;/iframe&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p>And i call the modal in the head part of my jsp like this :</p> <pre><code>&lt;script type="text/javascript"&gt; window.onload=function modalOverride(){ var myModal; $('modal-frame').style.display ='block'; myModal = new Control.Modal($('modalLink'), { afterOpen : function(){$$('.close a').invoke('observe','click',function(e){Control.Modal.close(); Event.stop(e);});}, opacity: 0.3, width: 675, fade: true, fadeDuration: 0.1, autoOpenIfLinked: false }); } &lt;/script&gt; </code></pre> <p>Now the link : <strong>Set up my Modal</strong> is part of a page containing many links. When i bring that page up, the java class that renders the data fro the modal also gets called. But this must happen only when , i click on the <strong>Set up my Modal</strong> link. </p> <p>Before some one tells me , this issue is not due to </p> <pre><code> window.onload </code></pre> <p>event, i have used it as otherwise the modal does not get loaded when i click the a fore mentioned link. I have tried by removing the <strong>window.onload</strong> event as well. If i do that, the java class still gets loaded and now my iframe does not get loaded . No errors come up in fire bug as well.</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.
