[izpack-users] PathSelectionPanel without using TargetPanel in 3.9 Show full header

[Lars Fischer]

Hello,

I want to create an installer which uses an not changable install-path.
With Izpack 3.8 this setting has worked:

<panels>
        <panel classname="HelloPanel"/>
        <panel classname="InstallPanel"/>
        <panel classname="ShortcutPanel"/>
        <panel classname="SimpleFinishPanel"/>
</panels>

After updating to 3.9 the created install.jar shows an exception, if I
try to install my application:

The missing PathSelectionPanel is in the package "TargetPanel" and not
included in the install.jar, because I dont use the TargetPanel.

Can I import the TargetPanel without showing it to the user or can I
disable it in the installation-process?

regards,
Lars Fischer
