debug cfc cfcomponent cfinvoke
I am new to cfcomponent. I am trying to convert some .cfm database pages (insert, delete, update, etc) into an oop DAO class. But I am using the method of:
A) code one function in .cfc, B) test by trial and error the function (Not debug), C) repeat.
I based my code on Part 3:"Gateways and Datasources" section of http://learn.objectorientedcoldfusion.org/wiki/Gateway .
Known unsolvable facts: 1) Unfortunately, I am developing on Vista 64bit (using dreamweaver) and cannot local debug because code (hundreds of .cfm pages) was written for microsoft access database. 2) I have to use "production server" for trial and error on remote host (readyhosting.com) 3) Production server is running Coldfusion 7 and do not have access to coldfusion administrator. 4) Do not have money in budget to downgrade vista 64 bit computer.
SUMMARY of PROBLEM: my .cfc is persistent. How do I stop .cfc from being persistent for debugging? Is there a deleteObject() or a workaround.
Details of problem:
I have two pages. 1) PeopleType_test.cfm and 2) PeopleType.cfc.

DETAIL of PROBLEM:
---------------------------------------------
I am using Internet Explorer 8.0 and dreamweaver cs3 and Coldfusion 7 (on remote production server). So here is what happens:
A) In PeopleTypeVer5.cfc, I edit the code (to fix compiler errors / logic errors) in "FindQryPeopleIdBy__names_gIdVer4" function
B) In both files, I change my "FindQryPeopleIdBy__names_gIdVer4" function name to "FindQryPeopleIdBy__names_gIdVer5"
C) I rename PeopleTypeVer4.cfc to PeopleTypeVer5.cfc
D) In PeopleType_test.cfm, I change TO <cfinvoke component="PeopleTypeVer5"...>
E) I ftp both files to server
F) I "refresh" PeopleType_test.cfm page in browser. Cfinvoke still thinks it is using old PeopleTypeVer4.cfc, not the new PeopleTypeVer5.cfc -- it does NOT refresh page? Even though I changed name?
G) I originally tryied to just perform steps A, B, E,F (skip steps C,D) and it does not work.
Q? How do I tell coldfusion to "expire" or force a reload of the new version of my PeopleTypeVer5.cfc component?
Q? or Is there some kind of workaround?
Q? or Is there some way to leverage a factory pattern to get around this problem?
Q? or Is there some way at runtime (say in a form field) that I could enter in the name of the .cfc I want to "load" or use?
Thanks
Dan
