so now that ive looked at ipagefactory what you want should be pretty easy
if you still want to use pages
mount a MyFactoryPage onto the /mountpointurl using indexedurlcodingstrategy
then in ipagefactory do this:
Page newPage(final Class<? extends Page> pageClass, final PageParameters
parameters) {
if (pageClass.equals(MyFactoryPage.class)) {
// we hit our marker factory page
String url=buildurlfromparameters(params);
String resolvedpageclass=resolveclassfromurl(url);
PageParameters resolvedparams=resolveparamsfromurl(url);
return super.newPage(resolvedpageclass, resolvedparams);
} else { return super.newPage(pageClass, parameters); }
}
MyFactoryPage is just an empty page, it really only serves as a marker for
when you hit that mount point.
makes sense?

the niceset woiuld be to use panels instead of pages. that way you mount a
page onto /mountpoint, when its hit you read the rest of the parameters,
query the db for the panel class, instantiate it and add it to the page.
nice and clean. there is really very little difference between page and
panel functionality-wise.
i dont have the code infront of me, but i would think this should be
doable within the pagemap factory
