anders,
myintention is to show as separate fields  in GUI. like we can view all
those details in table as fields by splitting the message,priority,Thread
etc., thats why i introduced '~' delimiter.

I have created an for that also.Its working fine with the outputted format
given previously.

cheers,
amarnath.
