Re: AW: Questions on workflow

Hello there to all.
 
I must apologize for being so late in answering this.  We have been in crisis mode here at work for about 3 months now, but are finally out of it.
 
There is a very much up to date version of the plugin, it is actually up to v3.0.6.  This includes (but not limited to) Eclipse 3.x integration, and XDoclet generation for new models.  I am getting ready to check the difference with the KeelWorkflow system that is in CVS and what I have locally.  I can only imagine that it is a large difference.  I will start a new thread for a discussion on that subject.
 
To get to your questions though:
 
1.  Typically what we do is to add a line in a try catch block such as:
            request.getPreviousRequest().put("error", "my_error");
     Then we can have a script like this:
            vars.get("error") != null
 
2.  Usually the behavior is going to be to continue until there is a return="true" added to the model.  You can use return="ifinput" to conditionally stop on your models.  Catch your exception and then add an Output for your error display to the response, this will cause the workflow to notice that there is something there to display to the user.
 
3.  Absolutely!  Bad Jeff, no biscuit!  As soon as I get my changes added into CVS, I am going to do a much more extensive tutorial for the workflow system.  I do apologize for the lack of documentation, this really is a sweet way of development.

Hi Thomas.

Oh dear. While it was not exactly what you were lookig for, I was 
hoping that you would be pull what you needed from it (as in, use the 
GUI to set up an Exception handler, and then have a look at the 
generated XPDL). I had no idea the release file was so far out of date.

Does anybody know if there is a more up to date version of RedKeel in CVS?

Regards,
Steve
