[kepler-dev] problems and fixes in cvs head of ptolemy

[Ilkay Altintas]

$CLASSPATH works for the Ptolemy II before we merge the Kepler code.
It doesn't work after we compile it with Kepler code.

Strange, $CLASSPATH should work.  $CLASSPATH is handled specially,
see
ptII/ptolemy/data/expr/FileParameter.java
> If a file name begins with the reference "$CLASSPATH", then when

I'm not sure why it would not be working unless there was a partial
merge where the version of FileParameter that predates the CLASSPATH
hacks.

    ok, I got the head of the ptolemy cvs to work with kepler. This is what
    I did:

    -add TextAttribute.java to the makefile in
    ptII/ptolemy/vergil/kernel/attributes

    -remake that directory

    -change line 87 of
    ptII/ptolemy/vergil/kernel/attributes/ImageAttribute.java to be
    source.setExpression("$PTII/doc/img/ptIIplanetIcon.gif");
    (instead of "$CLASSPATH/doc/....")

    -remake that directory.

    -change line 87 of

ptII/ptolemy/vergil/kernel/attributes/demo/AnimateVergil/AnimateVergil.xml
    to <property name="source"
    class="ptolemy.kernel.attributes.FileAttribute"
    value="$PTII/doc/img/ptIIplanetIcon.gif">
    (again instead of "$CLASSPATH/doc....")

    hope that works for you.  if it does, maybe forward this info onto the
    ptolemy folks.  It looks like someone just inadvertantly stuck in
    $CLASSPATH when it should have been $PTII.
