yes acutally this templist business broke my code.  the TectCtrls in the
traffic panel would were not being populated and the logfile.csv was
empty.

So should i replace:

#logger code---------------
        #  first new line
        self.logfile.write('\n')
        #  date and time
        self.logfile.write('%s,'%(str(strftime("%Y-%m-%d %H:%M:%S",
localtime()))))
		#  loop through each of the TextCtrl objects
        for k,v in self.fields.items():
            #  get the value of the current TextCtrl field
            f = field_values.get(k, None)
            if f:
                #  output the value with trailing comma
                self.logfile.write('%s,'%(str(f)))		
		#end logger code ----------------

With the code you posted above?

I am pretty sure that the reason i don't get the 'source' and 'dest'
fields is because of this:

#if the field 'duid' == 'hdu', then clear all the fields
        if field_values['duid'] == 'hdu':
            self.clear()

since the 'source' and 'dest' are in the LUD1 and not the HDU so it
doesn't update when the LDU1 comes through (if the LDU1) does actually
get serialized.  still haven't found a way to get to view the serialized
data.
