RawFileAdaptor does not work if shape is ['*']

Dear nomad,

the attribute a_browser=dict(adaptor='RawFileAdaptor') does not work if quantity shape is a vector:

detector_data = Quantity(
        type=str,
        shape=['*'],
        a_eln=dict(component='FileEditQuantity'),
        a_browser=dict(adaptor='RawFileAdaptor'))

Best Micha
