jbpm-web 3.2beta1: cannot complete task in simple example wo

[zipwow]

My goal and problem:
My goal was to get the jbpm-web console running with the simple process. I can load and start the process, but cannot complete the first task.

The setup details
I've got the 3.2beta1 webconsole running under Tomcat against a hypersonic database.

I used the IDE to create a process archive of the "simple" process in the examples folder. (examples/simple)

I loaded the archive successfully (as "ernie"), and started it successfully. A task seems to have been assigned to ernie, but I do not see how to specify the two task attributes (size and color), or how to represent the task as complete.

I notice that the "task form" tab is disabled.

The actions section has only a "reassign" option, which actually lists no users in the drop-down.

my questions
Is this definition expected to work?

Is a task form required? What's a task form, anyway? I see it in the wiki vision, but can't find other documentation on it.

To reply to myself on question #2 re:task forms, it looks like they are required:

http://jira.jboss.com/jira/browse/JBPM-732
http://jira.jboss.com/jira/browse/JBPM-596
http://jira.jboss.org/jira/browse/GPD-3

But I still can't find documentation on how they work.

I notice that the websale example has the forms.xml, but I get errors when executing that process (some errors on properties that are non-fatal, and ultimately a ava.lang.NoSuchFieldError: FORCE at org.jbpm.graph.node.Join.execute(Join.java:105)

taskforms are generated via the GPD and can then be manually adapted
