    <p>I'd imagine it has something to do with the fact that these two functions call each other, and as a far as I can tell, the <code>if</code> statements, once true, will always be true.</p> <pre><code>function removeForm(span) { if (previousSpan == null) return false; &lt; --Out of memory here according to IE if (previousSpan.parentNode.getElementsByTagName("form").length != 0) previousSpan.parentNode.removeChild(span.parentNode.getElementsByTagName("form")[0]); var result = (span == previousSpan); if (result) collapse(previousSpan); // &lt;--------------- previousSpan = null; // | return result; // | } // | // | function collapse(span) { // | if (previousSpan == span) removeForm(span); // &lt;-------- span.innerHTML = span.innerHTML.replace("▼", "►"); while (span.nextSibling != null) { span = span.nextSibling; if (span.className == "comment-content show"); span.className = "comment-content hide"; } } </code></pre> <p>Effectively:</p> <pre><code>var previousSpan; function removeForm( span ) { // ... if( span == previousSpan ) collapse(previousSpan); // ... } function collapse( span ) { // &lt;---here span is previousSpan, // &lt;-- always true because you're doing if(previousSpan == previousSpan) if (previousSpan == span) removeForm(span); // ... } // This makes subsequent comparisons in "removeForm()" always true as well, // because now it is guaranteed that "span" is the same as "previousSpan" </code></pre> <p>So once <code>span == previousSpan</code> in <code>removeForm()</code>, you're passing <code>previousSpan</code> to <code>collapse()</code>. The first thing <code>collapse()</code> does is checks to see if what it received is equal to <code>previousSpan</code>, which it always will be since that was the test to send it in the first place.</p>

    1. COYeah, you're right again. And I really feel stupid now. Thanks for the help I really appreciate it. I was looking at this code for hours yesterday and didn't see that.

    2. COWell, all of the answers I got were correct, I chose this one because it's contains some, well, 'graphic' and illustrates the problem. Thanks again.

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.
