How to use alternate OTB app Python syntax with StringList or ImageList parameters?

Description

Is the alternate Python syntax for OTB application parametrization works with StringList?

I've tried for instance :

band_math.IL=["image1.tif","image2.tif"]

It leads to an error from the SWIG wrapper. I did not find example of the use of image list and string list with theis syntax in the related tests in Wrappers/SWIG.

The error message generated on Ubuntu 14.06 with OTB-6.4 binary:

>>> app.IL=["test.tif", "test1.tif"]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/grizonnetm/software/OTB-6.4.0-Linux64/lib/python/otbApplication.py", line 1107, in __setattr__
    self.SetParameterValue(name.lower(), value)
  File "/home/grizonnetm/software/OTB-6.4.0-Linux64/lib/python/otbApplication.py", line 1023, in SetParameterValue
    return self.setParameterStringList(paramKey, value)
  File "/home/grizonnetm/software/OTB-6.4.0-Linux64/lib/python/otbApplication.py", line 1082, in __getattr__
    raise AttributeError("'%s' object has no attribute '%s'" % (Application.__name__, name))
AttributeError: 'Application' object has no attribute 'setParameterStringList'

Steps to reproduce

Describe as precisely as possible how to reproduce the bug. Try to isolate a minimal number of steps. Also describe reproducibility (always, random ...).

Configuration information

OS, OTB version or tag, information related to build (binaries, superbuild, system libs ...)

Should that say band_math.IL=["image1.tif", "image2.tif"]?

changed the description

I've indeed tested with double quotes. I've updated the bug description (add double quote around filepath) and also copy the SWIG wrapper error that given by the Python console.

Works for me in the latest OTB 6.6 nightly.

The workaround might be to use app.SetParameterStringList("il", ["image1.tif", "image2.tif"]).

you're right... (I've done a course on OTB last week with version 6.4 where I find the issue.

I close the issue. Thanks a lot @lnicola.
