[izpack-devel] Custom Actions NPE, patch

Hi Klaus, et.al.,

Sorry. I wasn't complaining. I just didn't understand at first. I 
thought the build-installer-listener tag associated the name with the 
class, but I see now that you might include several classes in there, so 
that wouldn't really work.

I made a patch for the doc on how to create a listener, but when I do an 
"ant build.docu" it doesn't change the html, and I don't see anything in 
the build.xml that would generate the node9.html from the node9.xml. I 
only see the copy of the xml. How do you gen the .html? Do you use a 
tool for editing the docbook xml?


PS. Since I haven't been able to view it in the browser, it might not be 
right yet. This is just to give you an idea of what I'm doing in case 
I'm on the wrong track.
