[izpack-devel] Issues while reading data from packs

[Michael Scherer]

Hi.

I'm currently trying to implement a BackupPanel which saves all
files that will be overwritten by the InstallPanel into a jar.File.

While doing this I'm trying to find all filenames by reading them
from the packs like the InstallPanel does ...

Now when doing "PackFile packFile = (PackFile)packStream.readObject();" I get
java.io.OptionalDataException
         at java.io.ObjectInputStream.readObject0(Unknown Source)
         at java.io.ObjectInputStream.readObject(Unknown Source)
         at 
com.izforge.izpack.panels.OpenBackupPanelAutomationHelper.doBackup(OpenBackupPanelAutomat
ionHelper.java:61)

What am I doing wrong here, copied must of the stuff from InstallPanel.
Mmmh, thanks for your help.

Greetings,
  Michael
