Passing a parameter value with spaces in it seems to work but trigger an error

[asmodehn]

Because I am managing multiple levels of parameters ( some in shell, some in python, some for underlying system ), I need to pass a parameter like:

--params="value1 value2 value3".

Currently I get : ERROR: Invalid remapping argument 'params=value1 value2 value3'

but this python code seems to work as expected : @manager.option('-p', '--params', dest='params', default='') def flask(params=''): try: app.logger.info('params%r', params) #get params in list: do_something(params.split()))

the logger gives me : params u'value1 value2 value3'

Any idea why the ERROR ?
