property not found

[arno1]

Hello,
I just downloaded the new (5.4) version of Activiti and updated my modelling plugin for eclipse and wanted to build a new simple example process for my colleague but there's an exception which tells me, that the propery of the used form is not found (I used the new feature of the "Form" section in Eclipse modeling plugin).
Explanation: In the first task I have a form (or want to have) where a name is entered, which is shown in the second task.
See Screenshot:

The exception is: "Unknown property used in expression."

So how does your expression look like? How do you reference 'firstName'?

I tried following things to reference the variable in the second task:

1. Hello ${firstName}!

2. Hello ${1}!

none of them worked.

Does the exception occur when you submit the form? Or request the form?

Can you show the XML the designer generated (the formProperties element)
