Dear Ptolemy-hackers,
I am trying to use the FilePortParameter and I had some problem,
When I call a asFile()
http://chess.eecs.berkeley.edu/ptexternal/src/ptII/doc/codeDoc/ptolemy/actor/parameters/FilePortParameter.html#asFile()
on an FilePortParameter which has not been used by the user I get
a nullPointerException, while in the doc it says that it should
return null.
My guess is that there is a bug in the FilePortParameter.java and
the following patch fixes my problem.
[EMAIL PROTECTED]:~/projects/opal/kepler/ptII$ svn diff ptolemy/actor/parameters/FilePortParameter.java
