Configuration properties are for transformation options, that are
configurable by the user of the transformation. I would not use them for
internal, global variables.

there are some bugs in the Helios release of Eclipse related to
dictionaries (also in combination with properties). I reported them and
they were recently fixed. See:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=322756
and
https://bugs.eclipse.org/bugs/show_bug.cgi?id=322758
Maybe these fixes also solve your problems?
Best regards,
Dennis

QVTo has both configuration and non-configuration properties. Instead of
"configuration property <name> : <type> = <value>" just use "property
<name> : <type> = <value>"...

Are you asking about mappings, or helpers, or both? For mappings, you
can control this by using in/out/inout, I think.

Hello Al,
oh wait, configuration properties don't have values... But
non-configuration ones do! Anyway, just omit the "configuration" keyword
and you have 'normal' properties.

Dennis
