Hi,

I created a metadata to hold 5 files together (1 primary and 4 data files). The file extension corresponding to the following metadata appears correctly in the list.
But When I try to upload the files. I get the following error.

Could you please help me fix this.

Here is the small class that I created to hold metadata:
class CompositeTest( Data ):
        file_ext="comptest"
        MetadataElement( name="data_lines", default=0, desc="Number of data lines", readonly=True, optional=True, visible=False, no_value=0 )
        composite_type="basic"
        
        def __init__(self,**kwd):
                Data.__init__(self,**kwd)
                self.add_composite_file('pedfile.txt')
                self.add_composite_file('mapfile.txt')
                self.add_composite_file('frequencyfile.txt')
                self.add_composite_file('datafile.txt')
        
        def init_meta(self,dataset,copy_from=None ):
                Data.init_meta(self,dataset,copy_from=copy_from)
