[Modeling-users] BR: fetch() doesn't bark on wrong class name

is simple to reproduce: just call EditingContext.fetch () with a
wrong class name. I got two different errors with two different
qualifiers, so I thought it was a bad qualifier, and then I realize my
typo. here are those errors:

Traceback (most recent call last):

Wow, thanks, but wait! :) I only made part of the work. Incidentally, I've just noticed
that the second part of your original message did not exhibit the same bug: it
is in fact due to qualifierWithQualifierFormat() not detecting some syntax
error, such as in:

name like "bob" AND isActive=1

(it is incorrect: '=' is not an operator, but '==' is)

I've just opened a new ticket for this one:
https://sourceforge.net/tracker/index.php?func=detail&aid=1032577&group_id=58935&atid=489335

Attached to this ticket is a patch solving it --it would be nice if enough
people could test it w/ their own qualifiers and report that it does not break
any valid ones, so I can integrate it into the main trunk.
