I think your problem is due to this bug: https://jira.codehaus.org/browse/IZPACK-919.
You can add a DefaultTargetPanel to solve it.

Hello,
I have extended TargetPanel, and created my own Panel (my project needs a customized screen, taking two installation paths).So I do not need another TargetPanel.
Are there any other workarounds?

To solve this problem, I added a DefaultTargetPanel which is not visible and a UserInputPath with two fields to enter my two installation pathes. I don't know if a better way exists.
