hi Michael,
first of all thanks for the kind words! use-cases indeed 'keep track' of the previous page state in case an exception occurs and we need to go back to the previous page but speaking of reusable use-cases is another story, I like the idea too but the problem is that when you reuse use-cases a lot you tightly couple them, which in effect makes it less suitable for reuse the most apparent example is the one where you send parameters to the next use-case, this one is probably going to 'read' them, but if another use-case also sends parameters (different ones, mind you) your target use-case becomes 'aware' of the other ones and depending on which use-case forwarded control to it it behaves a bit differently since it will work with different parameters each time (which we need to avoid) makes sense ? this example only covered the case where different parameters are sent from different use-cases, another problem of reuse is where a target use-case needs to 'return' to the calling source state of the original use-case, again it means the use-case becomes 'aware' of the ones calling it, and it will behave differently based on information outside of its own scope I don't know if I make sense here .. I'm going knee deep into this stuff every day I'm working on bpm4struts so I might not be 100% clear :-) -- Wouter Zoons - [EMAIL PROTECTED] http://www.andromda.org/ _________________________________________________________ Reply to the post : http://galaxy.andromda.org/forum/viewtopic.php?p=1844#1844 Posting to http://forum.andromda.org/ is preferred over posting to the mailing list! ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
