My problem is specifically relating to adding a DSN property into one of my service CFCs. I've added these details to the top of my cfc <cfcomponent displayname="CatalogueService" output="false" cache="true" cachTimeout="0">        <!--- Dependencies --->    <cfproperty name="CatalogueGateway"      type="model"                     scope="instance" />    <cfproperty name="DSN"               type="coldbox:datasource:dsn"         scope="instance" />       <cfproperty name="SessionStorage"      type="coldbox:plugin:sessionstorage"   scope="instance" />       <cfscript>       instance = structnew();    </cfscript>    <cffunction name="init" returntype="CatalogueService">     <cfargument name="DSN" type="string" inject="#instance.dsn.getName()#" hint="Datasource" />     <cfscript>     variables.DSN = arguments.DSN;     return this;     </cfscript>    </cffunction> I've kept the init very similar to what I've used to use to prevent needing to change any of the code. I was aware that coldbox 3 has standardised the name for wiring to "inject". However, I'm still on coldbox 2.6 (I think). So to keep inline I added this line to the coldbox.cml.cfm file and <yoursettings> section <Setting name="beanFactory_dslMarker"       value="inject"/> Unfortunately I'm receiving this error: ================= Application Execution Exception Error Type: Application : [N/A] Error Messages: The DSN parameter to the init function is required but was not passed in. ================= and can't figure out why?? Is anyone able to show me the error of my way? Thanks, Richard

Remove the constructor argument and just rely on the cfproperty injections. Luis Majano
