consequential changes from chaging a stereotype

[chadnash]

Sorry If I am completly the wrong track

I have a stereotype X with an attibute Fred
I make an element Y from that stereotype <<X>> appears in that element and gets a tagged value Fred
if I change the stereotype changing the attibute Fred to Joe nothing happens to the element Yill has the tagged value Fred and does not have a tagged value Joe.

I am essentially trying to use the stereotype as a class and the element as an instace of that stereotype .  I am probably on the wrong track.

The overall purpose is to relate use cases against functions from a function point count. ( I know there is a use case metric facility supported by EA and what I am attempting might not be a good Idea but bear with me) . The proposal is to create a Function stereotype and link functions ( created from that sterotype) to usecases via a connector that describes how the function points of the function should be attributed to the use case ( eg 50% of the function points)

SO the original problem comes about by me whanting to know how to manage consequential change if I change my Function stereotype.
Possibly it is the intential not to facilitate consequential change which I can live with. Howeveer may be I should be using somthing else other than stereotypes.  see also "custom element types" http://www.sparxsystems.com/cgi-bin/yabb/YaBB.cgi?num=1211248637

Perhaps a profile to extend use cases via stereotypes. The result would be new element 'types' that were based on use case. You would then use tagged values - as set up in your profile - to add the various values you'd use in your metrics.

Thanks This is what I am proposing to do
as I am a newbie your comment gives me more confidence.
However my specific question still stands
THat is
How can you get changes to stereotypes( or any metaclass sort of thing) to percolate down to the elements that are its instances?

Rather than try to explain it all...

Look up Synchronize in the help (and the forum). You'll get the idea.

This is an ongoing topic, as EA profile support continues to evolve. Check back often, and make sure you update your documentation with each new EA build.

HTH, David
