thanks Sunondo!

I can already give you a tip for displaying a list of users:

  1. on the action state representing the page you must have an
     outgoing transition
  2. add a trigger to this transition and give it a good name
  3. add a parameter (or more) to this trigger, let's say "users" which
     is a collection (or array) instance
  4. add a tagged value to that parameter:
     @andromda.struts.view.field.type = select

this should render a list allowing multiple selections, the action form will contain a variable "usersBackingList" that contains the complete list of users; there will be another variable "users" that represents the collection of selected users (always a subset of the backing list)

if you prefer a combobox instead of a list you can just change the type of the "users" variable to a non-collection object (you probably want to rename to "user" too)

that's all you need to do, just make sure the rest of the activity graph is correct too, soon the cartridge will help you there :-)

Thank you, that worked. I now have a working example where I can create
a new user using the generated code. Thanks to you and Wouter for all
your help. This is really cool stuff!
Now I will try to add more action states to the activity diagram. I need
to display the list of users created by the previous steps. Let's see
how that goes. :-)

Hi Sundondo,
This is probably because your HSSQL ds.xml file needs
to have the following things uncommented:

and:

So uncomment those things and it should work.

Hi Chad,
I have a question about creating the tables used in the AnimalQuiz sample. When I run the initializeSchema then I get the error included at the bottom of my email. I looked in my JBoss deploy dir and saw the hsqldb-ds.xml config file. I modified the connection url there but then jboss startup threw some exceptions. Do you know what I need to do to set up hsqldb in order to create the tables? I went to the hsqldb site on sourceforge but didn't find much info there.
In the older version of Andromda (2.x) the tables
were getting created automatically. However in the
new version it complains while trying to create a
new entity that the table does not exist. Am I doing
something wrong in the new version?
Thanks for your help,
Sunondo
