tracker issue : CF-3037908

Problem:

cfproperty declaration in component interferes with inheritance.

beanB extends beanA. beanB adds FieldC to FieldA and FieldB declared in beanA. beanB contains cfproperty declarations for FieldA, FieldB, and FieldC. If beanB is populated using setters for FieldA, FieldB, and FieldC, only FieldC is properly set. Removing the cfproperty declarations results in the expected behavior.

Method:

/**** beanA ****/
<cfcomponent displayname="beanA">
  
  <cffunction name="init" access="public" returntype="beanA" output="false" displayname="component 'Constructor'" hint="I initialize this component.">
    <cfargument name="FieldA" displayname="string FieldA" hint="initial value for the FieldA property" type="string" required="no" default="" />
    <cfargument name="FieldB" displayname="string FieldB" hint="initial value for the FieldB property" type="string" required="no" default="" />
    <cfscript>
        variables.instance = structNew();
        variables.instance.FieldA = arguments.FieldA;
        variables.instance.FieldB = arguments.FieldB;
    </cfscript>
    <cfreturn this />
  </cffunction>
