[werkflow-user] Hanoi example failure

Discussion:

Hi,

I recently checked out werkflow-core and ran the maven:werkflow-hanoi
target. After passing all the tests, the example ran through but threw
an Exception part way.

Can anyone tell me if I've got something misconfigured?

Many thanks.

Peter

The output was :

Hi,

I just fixed the Hanoi example in CVS. It is running now again.

In case you use any condition (e.g. if, switch, while, etc) be aware
that recently werkflow was changed to use Ognl as default for condition
evaluation. It is planned to make this configurable, but for now you can
check out http://www.ognl.org for more information on Ognl syntax and
possibilities.
