Bingo! You pinpointed both the bug, and the reason why the first code worked
even though the code was syntactically bogus. :-) Full score!

I was confused for a whole minute until Johan pointed out the error. I was
of course, as always, concentrating on the place where I did the change and
the place where the error appeared. That is usually where the bug is. :-)

I won't look into the DTML Parser code right now. Don't need no headache ;-)

But this is my first guess:

> > 

DTML looks at "getEasyLanguageService" and does an implicit
"getEasyLanguageService()". So now "getEasyLanguageService" (as an attribute
in the DTML namespace) represents the actual service object the method
should return.

> >   

ELS represents the service object now

> >   
> >  > 

getEasyLanguageService() is called explicitly, and in the "", so DTML does
no magic. It does NOT put the returned service object into the namespace as
"getEasyLanguageService" (as it would do in the first example)

> >   

the method "getEasyLanguageService", not its return value (i.e. the language
service object) is passed to ELS

[Zope-dev] This was fun!!!

2002-10-15 Thread Lennart Regebro 

Here was a fun error I had. Try and figure out where the bug is!

I had this dtml-code:


  
  

  
  


This worked fine. I then changed it to this:


  
  

  
  


Now this fails, and it fails in:
   
with an "function attributes not accessible in restricted mode" error!

Now, where is the bug? :-)

First answers get 5 ZopeZen coolness credit points. An explanation to why
the first version works gets 100 points! :-)
