Hi guys!

I'm playing with Explorer2. First of all, congratulations! I really like it. Vaadin it's a really powerful tool  :D.

But I've found a problem (perhaps cause it still under development)… Processes with forms doesn't work fine.
When I try to run a process:
  - With no form: it works perfectly.
  - With an "easy" form (without variables): it doesn't show any form but it runs.
  - With "normal" form (e.g. VacationRequest): I can click "Start flow" button, but when I press "Start proces" button it throws an Exception:

GRAVE: Error while closing command context
org.activiti.engine.ActivitiException: Unknown property used in expression
        at org.activiti.engine.impl.el.JuelExpression.getValue(JuelExpression.java:48)
        at org.activiti.engine.impl.bpmn.behavior.UserTaskActivityBehavior.execute(UserTaskActivityBehavior.java:52)

        at org.activiti.engine.impl.interceptor.CommandContext.performOperation(CommandContext.java:76)
        …

As you can see below, forms are loaded correctly:

Really, it doesn't matter cause is not an estable version. But I wondered if it will support html forms… It will, isn't it?

P.S.: Do anybody knows when is gonna be ready first version  :mrgreen: ?

Best regards!
