hi everyone!
here's a first attempt at cleaning up usecases.js:
http://people.apache.org/~nettings/usecases.js
as you can see, i've put some repetitive stuff into functions and ripped
out cforms-specific code. all other usecases work.
as to cforms, i'm planning to add a generic solution for custom
flowscripts, inspired by the existing mechanism of <intro/> and
<outro/>, which should be ok for cforms. if it works out like i think it
should, you will be able to pass two urls with custom flowscript
snippets to the usecase declaration - one for the main loop, and the
other for the "submit" case.
i'd also like to get rid of the duplicate view methods (<view
template=""../> and <view uri="".../>). both do almost the same now anyway.
the remaining one (i'm favouring "uri") will take a protocol-less uri
that will be fed to the root sitemap if it starts with a slash, and to
the usecases.xmap if not. this will make our framework consistent with
the cocoon documentation. any objections?
doug has recently requested an option to switch from sendPageAndWait to
sendPage, to cater to one-shot usecase views. is that a purely
hypothetical scenario, or will people use it? i can add an option, but
i'd like to avoid creating dead code.
here's how the xconf view declaration might look:
<view uri="/modules/foo/usecases/foo-mogrify.jx"
loopFlow="/modules/foo/flow/mainLoop.js"
submitFlow="/modules/foo/flow/submit.js"
menu="false|true"
createContinuation="false|true"
/>
where createContinuation and submitFlow are mutually exclusive.
this approach will also eliminate the cforms-specific code in UsecaseView.
if anybody is using custom variants of the cforms module for some more
advanced stuff, i would be glad to hear about them, in order to find out
about limitations in my outline.
as always, comments and improvements appreciated.
