[coldspring-dev] using parentBeanFactoryKey

Tue, 07 Mar 2006 17:23:22 -0800


OK I think I found the issue....
When a parent exists, singletonCacheContainsBean will always ask the parent if the bean exists, therefore if it does not exist in the parent, singletonCacheContainsBean will return false, even though the bean really exists in the child cache.

<cffunction name="singletonCacheContainsBean" access="public" returntype="boolean" output="false">
        <cfargument name="beanName" type="string" required="true" />
        <cfset var objExists = 0 />
        <cflock name="SingletonCache" type="readonly" timeout="5">
                <cfset objExists = StructKeyExists(variables.singletonCache, beanName) />
        </cflock>
Current
<cfif objExists AND isObject(parent)>
Fix
<cfif (NOT objExists) AND isObject(parent)>
                <cfset objExists = parent.singletonCacheContainsBean(arguments.beanName)>
        </cfif>
        <cfreturn objExists />
</cffunction>
