    <p>I have a jQuery ajax call in my coldfusion page which is as below:</p> <pre><code>function getData(paramValue) { var URL = "/cfc/**somecfc.cfc**?method=**somemethod**"; $.ajax({ type: "POST", url: URL, data: ({ paramValue: paramValue}), dataType: "text", success: function(data) { alert(data);}, error:function (xhr, ajaxOptions, thrownError){ alert("xhr.status = " + xhr.status); alert("thrownError = " + thrownError); } }); } </code></pre> <p>some method in somecfc returns a text value. When I try to view the data within success, it shows the following error:</p> <p><code>"&lt;wddxPacket version='1.0'&gt;&lt;header/&gt;&lt;data&gt;&lt;string&gt;ERROR: . &amp;lt;br /&amp;gt;Element SETTINGS is undefined in a Java object of type class [Ljava.lang.String;.&lt;/string&gt;&lt;/data&gt;&lt;/wddxPacket&gt;"</code></p> <p>Since it shows the error from within <strong>success</strong>, there seems to be problem with the return data or ?</p> <p>Any help to fix this would be highly appreciated.</p> <p>the code in the cfc method is as follows: </p> <pre><code>&lt;cffunction name="somemethod" access="remote" returntype="any" o&gt; &lt;cfargument name="paramValue" type="string" required="yes" &gt; &lt;cfset var returnValue = "" /&gt; &lt;cfquery name="someQry" datasource="#variables.settings['dsn']#" &gt; SELECT value_name FROM valuesTbl WHERE value_Id = &lt;cfqueryparam value="#arguments.paramValue#" cfsqltype="cf_sql_varchar"&gt; &lt;/cfquery&gt; &lt;cfset returnValue = #someQry.value_name# /&gt; &lt;cfreturn returnValue /&gt; &lt;/cffunction&gt; </code></pre> <p>returnValue variable has only 1 string value. Hope this helps!</p>

    2. COYou'll need to post the code in your cfc, since that's where the error is coming from.

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.
