As noted on Slack, this is because we have invoke implicit accessors defaulting to try in boxlang. this.tabs = foo is trigger this.setTabs(). And since the setTabs method has this.tabs = … inside of it, it’s endless recursion time.

Note: Removing the declared property of the same name will allow the component to instantiate.
When calling:
createObject('component', 'DoubleInit').init()With a double init component of:
<cfcomponent displayname="DoubleInit" namespace="DoubleInit" output="no"> <cfproperty name="tabs" default="0" type="numeric" /> <cffunction name="init" access="public" output="no" returntype="any"> <cfargument name="tabs" type="numeric" required="no" default="0" /> <cfset this.tabs = arguments.tabs /> <cfreturn this> </cffunction> <cffunction name="setTabs" access="public" output="no" returntype="any"> <cfargument name="tabs" type="numeric" required="no" default="#this.tabs#" /> <cfset this.tabs = arguments.tabs /> </cffunction> </cfcomponent>A stack overflow error will occur:
