Markus,
thanks!

Alas, the page (to which I need the special access) is not a new one to be
created, but an existing non-trivial one; what's worse, it is not a direct
subclass of OCSComponent, there's an intermediate class with another shared
functionality. Aside of the inherited stuff, the page refers to the session
both in its own code and also in the HTML template.
Thus, whilst this approach is technically possible, I am afraid it might prove
more legwork than writing the component code afresh.
Unless.... hmmm, I wonder. Can I create an independent session for one specific
page only this way?
===
class ThatDarnedComponent extends SomethingElse /* which extends OCSComponent
which extends ERXComponent */ {
Session specificPageOnlySessionAccess; // set up if no other page should
share login
Session session() {
return specificPageOnlySessionAccess?:super.session()
}
... ... all the rest unchanged
===
class DirectAction extends WODirectAction {
WOActionResult thatDarnedAction() {
def page=pageWithName("ThatDarnedComponent")
page.specificPageOnlySessionAccess=new Session() // not shared, but
specific for the page only; other pages would get different session
page.specificPageOnlySessionAccess.currentUser=... user determined from
request, details unimportant ...
return page
}
... ...
===
Might that work perhaps? Would any other component (if accessed anyhow) get a
different session? Or would there be problems due to the specific session
somehow shared, e.g., through a context or whatever?
Thanks and all the best,
OC
