I think that you're defining your method like this:
def sping2(self,fileID,lines):

but in your call you're saying that the parameters are optional:
<dtml-let link="sping2(fileID='myPDFfile.pdf',lines=mylines)">
which isn't true.

if they are not optional, then you have to call the method like this:
<dtml-let link="sping2(fileID,lines)">

Otherwise, you have to define your method on this way:
def sping2(self,fileID='my default',lines=[''])
