[Zope] External Methods & Symbol Table & BioPython

[Cristian S. Rocha]

Hello,

I'm trying to use BioPython in an External Method but it return
"ImportError: cannot import name FastaReader" (and others functions). I
check some "tricks" but nothing change.

Then I modify my external method to know what happening with the symbol
table:

The program:

"""
def SequenceRead(SequenceString):
	import StringIO
	import Bio.SeqIO.FASTA

	return vars(Bio.SeqIO.FASTA).keys()

"""

When I run it at command line the function return:

"""
['Bio', 'string', 'Seq', 'FastaReader', '__builtins__', '__file__',
'SeqRecord', 'FastaWriter', '__name__', 'os', '__doc__']
"""

That's ok. But When I run it in Zope the function return:

"""
['Bio', 'string', 'Seq', '__builtins__', '__name__', '__file__', 'os',
'__doc__']
"""

The function lost the "FastaReader", "SeqRecord" and "FastaWriter" in
the symbol table!!!

What's wrong? Must I change something to change them to public
functions?

Thxs,
Cristian.
