I've never heard of this init-method thing. To get ColdSpring to inject your
Articles component you just need a setter in your Category component.
ColdSpring matches the name of the property to the setter (so property
Articles looks for setter setArticles). So make sure in your XML the name of
the property matches the name used in the setter.
<cffunction name="setArticles" access="public" returntype="void"
hint="Articles setter">
<cfargument name="articlesCFC" type="Components.Articles"
required="true" />
<cfset Variables.articlesCFC = arguments.articlesCFC />
</cffunction>

I figured ColdSpring would just run some magic on my properties and
automatically figure out that they should be set in the init-method rather
than in the init() constructor, but CS threw an error at me indicating it
was still looking for a generic set[myDependency]() method. Here's my
config.xml:
<!-- File loaded by ColdSpring to perform dependency injection -->
<beans>
<bean id="Articles" class="Components.Articles" singleton="true">
<constructor-arg
name="datasource"><value>${datasource}</value></constructor-arg>
</bean>
<bean id="Categories" class="Components.Categories"
singleton="true"
init-method="setup">
<constructor-arg
name="datasource"><value>${datasource}</value></constructor-arg>
<property name="articleCFC"><ref bean="Articles"
/></property>
</bean>
</beans>
And here's my Categories.cfc:
<cfcomponent hint="Add/Edit/Delete Categories">
<cfset Variables.datasource = "" />
<cfset Variables.articlesCFC = "" />
<cffunction name="init" access="public"
returntype="Components.Categories" hint="I initialize myself">
<cfargument name="datasource" type="string"
required="false" />
<cfset Variables.datasource = arguments.datasource />
<cfreturn this />
</cffunction>
<cffunction name="setup" access="public"
returntype="Components.Categories" hint="I post-initilize myself for
circular dependencies">
<cfargument name="articlesCFC"
type="Components.Articles" required="false" />
<cfset Variables.articlesCFC = arguments.articlesCFC />
<cfreturn this />
</cffunction>
</cfcomponent>
What's the syntax for making the init-method concept work? I googled
around
a bit, but kept getting matches regarding the regular init() constructor
rather than the init-method usage.
