xml importing: "split" error

[aksiotis]

I was using a specific xml file inside the NFB lab and it works there. However, when I tried to import the file using Studio, I got the message:

Traceback (most recent call last):
  File "c:\users\владислав\nfb_studio\nfb_studio\experiment_view.py", line 510, in actionImport
    ex = Experiment.import_xml(data)
  File "c:\users\владислав\nfb_studio\nfb_studio\experiment.py", line 269, in import_xml
    group = Group.nfb_import_data(group_data)
  File "c:\users\владислав\nfb_studio\nfb_studio\group\group.py", line 102, in nfb_import_data
    group.repeats = [int(number) for number in data["sNumberList"].split(" ")]
AttributeError: 'NoneType' object has no attribute 'split'

This seems incorrectly formatted. The group has a single item, "signal", but the sNumberList field has no items, when it should have had a single 1 to indicate that this "signal" block is executed once.

@nikolaims How should I parse this? If sNumberList is empty just insert N number of ones to match the number of items in sList?

Apparently NFB Lab does not validate invalid field such as this. So this is not a bug - the file is actually invalid.
I will keep this open until I implement a proper message for incorrectly formatted XML files.
