[CFCDev] calling a component from within the itself when it was instantiated in the calling page

Pardon my potentially colossal ignorance here, but -

If in a cfm page I do this:

// instantiate the Egg component

variables.eggs = createObject("component","myPath/eggs");

// use it here to create a new Egg record

variables.args = structNew();

variables.args.myArg1 = "blah";

variables.nEggs = variables.eggs.newEgg(argumentCollection=variables.args);

And - newEggs() within eggs.cfc looks something like this:

INSERT ...

</cfquery>

Now - right here, after the insert query, I want to check and see if the insert itself happened and the new record exists, so ---

My question is - when I'm inside of newEgg() within egg.cfc, which was instantiated on the calling page, and newEgg() calls getEgg(), do I need to instantiate egg.cfc again since the component itself may not be aware of the fact that it was instantiated on the calling page, or what?

One example of the code following the insert query might be:

// instantiate the component

instance.eggs = createObject("component","myPath/eggs");

// use it to check to see if the new Egg record exists instance.args.eggID = arguments.myArg1;

instance.newEggCheck = instance.eggs.getEgg(instance.args.eggID);

// toggle return variable based on results of above test

if(instance.createFacilityCheck.recordCount IS 1)

instance.theReturnString = instance.theNewEggID;

else

instance.theReturnString = "ERROR";

</cfscript>

</cffunction>

Or, does it/should it know the object exists already? Something like

this:

// check to see if the new Egg record exists instance.args.eggID = arguments.myArg1;
