hello one and all,

i read the article in the book: 
http://web2py.com/books/default/chapter/29/4#Sharing-the-global-scope-with-modules-using-the-current-object

and so i added to my db.py model file after the assignment of db and auth:

from gluon import current
current.db, current.auth = db, auth

and i created a new module called mcp0.py under the modules section and 
added say the function:

def chkSession(subscribing=False):
    auth, db, session, request, response = current.auth, current.db, 
current.session, current.request, current.response
    tCase, tSheet = db.cases, db.worksheets
    ...
    return etc

being sure that "current" is called in the function and not globally to 
make sure the threads are kept straight.

now this is where it gets strange, when i generate a link like 
https://domain.com/app/controller/function/30 and click on it, the 
application returns an error because the argument of 30 changes to None.  
now if i type the 30 back into the URL, it will return the page ok.  but 
clicking on the link, which is a correct link, somehow the argument list 
gets lost between the click and the function maintaining that argument 
list.  and again, if i manually type it, the 30, the page loads fine.

weird and i don't understand it.  ok, let me know, lucas
