Re: [werkflow-user] Hanoi example failure

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.
