[izpack-devel] Serialization problem

[damo]

I have been trying to add some new functionality to izpack so that it can use variable dependencies in a similar way the OS tag does.

eg.
<fileset dir="Database" targetdir="$INSTALL_PATH\">
   <installType type="something">  
      <include name="**\**\**\*"/>
   </installType>
</fileset>

the "something will be set in a panel that is near the start of the install"

it is supported for <file><fileset><singlefile><parseable><executable> 
based on the value of the variable a fileset (for instance) would be copied or not. 
I have implemented it fully and the ant task builds successfully but when i try to compile using compiler.jar i get an error 

the fileset where i use the tag <installType> is used in "Pack 2: Application Server" and that's where i get this error...

[end...]

any help would be great as i would like to contribute to this project and hope that this can be implemented into izpack at some stage as it would be a very handy addition to the project.

NOTE: com/izforge/izpack/installer/InstallData.java does exist 

i have also assigned a new serialVersionUID but i think that there is a special way to work them out as the error refers to SUID

at java.io.ObjectStreamClass.getDeclaredSUID(ObjectStreamClass.java:1474)
at java.io.ObjectStreamClass.access$400(ObjectStreamClass.java:47)

this to me suggests that there is a security access problem because the serialVersionUID is invalid.

if anyone knows what i need to do or even if there are any serialVersionUID available to use i would be gratefull to hear them. 

Thanks Damien

Regards Damien.
