Strange behavior, objectid() method in component.cfc

So I was working on something OOP :-). And I am trying to use Hal Hellms BaseComponent.cfc that all CFCs that don't extend anything should extend. For the purpose of this post I reduced it to two methods:
<br /><cfcomponent displayname="BaseComponent" hint="I am the base class for all components"><br /><br /> <cfset variables.null = "|\| |_| |_ |_" /><br /> <cfset variables.instance = StructNew() /><br /> <cfset variables.objectID = CreateUUID() /><br /><br /> <cffunction name="init" access="public" output="false"><br /> <cfreturn this /><br /> </cffunction><br /> <br /> <cffunction name="objectID" access="public" returntype="string" output="false"><br /> <cfreturn variables.objectID /><br /> </cffunction><br /> <br /></cfcomponent><br />
The way I was using it is I included it into ColdFusion component.cfc that all CFCs extend by default:
<br /><cfinclude template="/common/vendor/basecomponent/BaseComponent.cfc"><br />
So I also make test CFC and a cfm page:
<br /><cfcomponent output="false"></cfcomponent><br />
<br /><cfscript><br />Obj = createObject("component","ObjectIdTest");<br /></cfscript><br /><cfdump var="#Obj#"><br />
When I run cfm file and expend the dump output I see following:



As you can see the objectid() method is missing.

Now I remove the include from component.cfc and make my test component extend BaseComponent
<br /><cfcomponent extends="common.vendor.basecomponent.BaseComponent" output="false"><br /></cfcomponent><br />
Run cfm again and get following:


Now objectid() method is seen in the dump.
