    <p>I have two CFC's which are Beans with DAO functions. I have set up inheritance where the child cfc extends the parent.</p> <p>Both objects have identical structures; Functions: init, read, etc. and Properties: ID, etc. </p> <p>When I create the child object, I pass an ID, which reads the data, getting the foreign key parentID for the parent and then Super.init() is called with appropriate parameters.</p> <p>My unexpected results are: Both the ID for the child and the parentID are the same and are the parentID value when the object is returned. The childs variables.ID is overwritten after the super call. I assume that the variables scope is accessible by both, so when parent sets variables.ID it overwrites the child variables.ID. Can this be avoided without naming IDs differently?</p> <p>The read function of the parent object does not appear to execute. If I rename the parents read function 'read2' for example, the function executes. I also suspect that the functions reside in a shared scope and therefore the childs read function is executing.</p> <p>Is there any way to maintain the same cfc structures and get this functionality to work as expected?</p> <p>Thanks in advance.</p> <pre><code>&lt;cfcomponent accessors="true" extends="Custom" output="false"&gt; &lt;cfproperty name="ID" type="numeric" /&gt; &lt;cfproperty name="listID" type="numeric" /&gt; &lt;cfproperty name="customfieldID" type="numeric" /&gt; &lt;cfscript&gt; variables.dsn = ''; &lt;/cfscript&gt; &lt;cffunction name="init" access="public" output="false" returntype="ListCustom"&gt; &lt;cfargument name="dsn" type="string" required="true" /&gt; &lt;cfargument name="ID" type="numeric" required="true" /&gt; &lt;cfargument name="listID" type="numeric" required="false" default="0" /&gt; &lt;cfargument name="customFieldID" type="numeric" required="false" default="0" /&gt; &lt;cfscript&gt; variables.dsn = arguments.dsn; variables.ID = arguments.ID; variables.listID = arguments.listID; variables.customFieldID = arguments.customFieldID; if (variables.ID){ read(); if (variables.customFieldID){ Super.init(dsn=variables.dsn,ID=variables.customfieldID); } } &lt;/cfscript&gt; &lt;cfreturn this /&gt; &lt;/cffunction&gt; &lt;cffunction name="read" access="private" output="false" returntype="void"&gt; &lt;cfquery name="local.q" datasource="#variables.dsn#"&gt; SELECT customfieldID, listID FROM listCustomFields WHERE ID = &lt;cfqueryparam value="#variables.ID#" cfsqltype="cf_sql_integer"&gt; &lt;/cfquery&gt; &lt;cfif local.q.recordcount&gt; &lt;cfset variables.listID = local.q.listID /&gt; &lt;cfset variables.customFieldID = local.q.customFieldID /&gt; &lt;/cfif&gt; &lt;/cffunction&gt; </code></pre> <p></p> <pre><code>&lt;cfcomponent accessors="true" output="false"&gt; &lt;cfproperty name="ID" type="numeric" /&gt; &lt;cfproperty name="fieldName" type="string" /&gt; &lt;cfscript&gt; variables.dsn = ''; &lt;/cfscript&gt; &lt;cffunction name="init" access="public" output="false" returntype="Custom"&gt; &lt;cfargument name="dsn" type="string" required="true" /&gt; &lt;cfargument name="ID" type="numeric" required="true" /&gt; &lt;cfargument name="fieldName" type="string" required="false" default="" /&gt; &lt;cfscript&gt; variables.dsn = arguments.dsn; variables.ID = arguments.ID; variables.fieldName = arguments.fieldName; if (variables.ID){ read(); } &lt;/cfscript&gt; &lt;cfreturn this /&gt; &lt;/cffunction&gt; &lt;cffunction name="read" access="private" output="false" returntype="void"&gt; &lt;cfquery name="local.q" datasource="#variables.dsn#"&gt; SELECT fieldName FROM CustomField WHERE ID = &lt;cfqueryparam value="#variables.ID#" cfsqltype="cf_sql_integer"&gt; &lt;/cfquery&gt; &lt;cfif local.q.recordcount&gt; &lt;cfset variables.fieldName = local.q.fieldName /&gt; &lt;/cfif&gt; &lt;/cffunction&gt; </code></pre> <p></p>

    1. COCan you share some code? Also, in a parent/child relationship, I am not sure having child extend parent is the way to go. Both could extend a 'base' object, but not sure child extending parent is the way to go.

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).
