[kepler-dev] fileOrURLPort broken in BinaryFileReader ?

Hi Tristan,
I certainly see the same err that you reported - namely that
specifying the file name on the port never transfers the file name to
the internal parameter!
The problem seems to be in the 'if (fileOrURLPort.hasToken(0)) {'
statement in the '_openAndReadFirstBytes' method. No token is being
retreived. I think that the problem is that this method is being called
in the initialize and preinitialze methods and tokens are not present
yet when these are fired. I commmented out the calls to
openAndReadFirstBytes in these methods and added it to the very top of
the fire method and everything worked OK!
I will defer to Efrat to take a look and see if my conclusion is
correct, since this is a GEON actor.
