[vwnc] Unhandled Exception: a primitive has failed.

Jim Harsh
Hi All,

I have a application which is basically a data flow/visual
programming approach to Image analysis and simulation. Different
classes are instantiated by selecting and placing "glyphs" on a
"canvas" and then connecting them together to indicate the data flow.
There are approximately 300 glyphs/classes. One of the
classes,  Cauchy2DParameter is subclassed from Bennett2DParameter.
When I try to instantiate the Cauchy2DParameter on a Windows box (
XP) it works fine, however,  when I try on a Linux 32 box, if fails
with an Unhandled Exception: a primitive has failed. Looking at the
stack this exception is raised from
HandleRegistry>>evaluateWithFullProtection. If I ftp the image file
from the window box to the Linux box I get the same error. This is
the only class that causes this error.

Any Ideas?

Thanks,
Jim

The more interesting question is WHICH primitive failed. Most likely you
are requesting some resource from the OS (a Pixmap, external library
call, file, socket or process), and Windows is happy to give it to you
but Linux isn't. Maybe it can't find it, or says what you are asking for
is too big or the wrong format (e.g. bitmap depth), or maybe you don't
have permission for it.

By the way, your language sounds really interesting; is there anything
published about it? Would it be possible to have an example screenshot
and/or short description of your visual language to put on the
Domain-Specific Modeling Forum's site?

HTH,
