thanks Gabriel,
i wrote the function below, but am now getting an "Error in
sys.exitfunc:" error (which disappears when i comment out the last two
lines below):
class write2Log:
def write(self, x):
if x!=',':#ignore if a comma
if str(x).count('\n')==0:
buffer += str(x)
else:
list = str(x).split('\n')
logger.debug(buffer)
buffer = ""
for text in list:
logger.debug(text)
sys.stdout = write2Log()
sys.stderr= write2Log()
any ideas what might be wrong?
thanks again
