Um, except that id is not always a method ;-(, hence the _['id'] idiom
(see discussion earlier this week)

Thanks for the quick fix.  I really thought it was time to go to bed.  Now that
it makes sense, I have to rethink whether I have enough evidence that I'm
tired.  :-)

yep.. well... this is quite a common question, all up.  It comes from people 
using shorthand, but not relaising it.  sometimes i wonder if this feature 
should be removed.

the line:



is actually shorthand for:



which means your expression is handled as a python expression, not a DTML 
one.  In which case, you are comparing a function object (id)  with a string 
object ('index_html').

the simple fix is, of course, to 'call' the function



should do what you're expecting.

[Zope] Help with simple dtml-if compare

[Patrick J.M. Keane]

Bug?  Or am I missing something.

Create a default document called 'index_html', with these contents:



index_html == 

index_html != 



Basically, we're comparing the document id -- "index_html" to the string
"index_html".

If you run it, the results say:

index_html != index_html

Why is that??  Any help?  Ideas?

Thanks
PK
