    <p>Your two main options are listToArray(myList) and the java method myList.split(), as noted in previous answers and comments. There are some things to note though.</p> <ul> <li>By default ColdFusion list functions ignore empty list items.</li> <li>As of ColdFusion version 8, listToArray takes an optional third argument, includeEmptyFields, which is a boolean controlling that behavior, defaulting to false.</li> </ul> <p>For example:</p> <pre><code>listToArray("asdf,,,qwer,tyui") is ["asdf", "qwer", "tyui"] listToArray("asdf,,,qwer,tyui", ",", true) is ["asdf", "", "", "qwer", "tyui"] </code></pre> <p><strong>Re java split:</strong></p> <p>Like other java functionality that pokes up through the ColdFusion layer, this is undocumented and unsupported</p> <p>In Adobe ColdFusion 8, 9, and 10, but not in Railo, this is a syntax error:</p> <pre><code>a = "asdf,,,qwer,tyui".split(",") </code></pre> <p>But this works:</p> <pre><code>s = "asdf,,,qwer,tyui"; a = s.split(","); </code></pre> <p>As far as I can see, Adobe ColdFusion treats the result of .split() like a ColdFusion array:</p> <ul> <li>CFDumps show it as an array</li> <li>It's 1-based</li> <li>You can use arrayLen on it</li> <li>You can modify its elements in ColdFusion</li> <li>There may be other behaviors I didn't check that aren't like a CF array, but as above, it's unsupported</li> </ul> <p>In Railo:</p> <ul> <li>Debug dumps show it as Native Array (java.lang.String[])</li> <li>The other statements about its very array-like behavior are still true</li> </ul> <p>That's in contrast to real java arrays, created with createObject("java", "java.util.ArrayList").<br> <em>NOTE: That's only partly correct; see edit below.</em></p> <ul> <li>For instance, in Adobe ColdFusion, elements of a java ArrayList can't be modified directly with CFML</li> <li>In general, Railo handles java arrays more like ColdFusion ones than ACF</li> </ul> <hr> <p><strong>Edit:</strong> Thanks Leigh, I stand corrected, I should stick to what I know, which is CF way more than java.</p> <p>I was reacting to the comment saying that the result of .split() "is not a ColdFusion array, but a native Java array. You won't be able to modify it via CF", which is not the case in my experience. My attempt to clarify that by being more specific was ill-informed and unnecessary.</p>

    1. CO*java arrays, created with createObject("java", "java.util.ArrayList")* An `ArrayList` is not the same as a java array. ArrayList's are a type of `java.util.List` and *can* be modified, same as any CF array. (Beneath the hood, ACF "arrays" are java.util.List's too). A "real" java array is different. A java array's *size* is immutable. Meaning you can modify its elements, but you cannot perform operations that change its size ie add or remove.

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.
