Installer uses the wrong harness

Hi everyone,
I create the installer for my platform app through right click on the
project in Project Explorer -> Package As -> Installers.

The app is set up to use a custom platform, which is registered in the IDE.
All works well and the executables (launchers) are taken from the harness
that I provide with the platform.

BUT: the installer panels are generated from stubs that reside in the
harness that comes with the IDE.

When you invoke "Package As -> Installers", the command that I see in the
output window is:

ant -f "*<NB Install Path>*\\harness\\nbi\\stub\\template.xml"
"-Dnbi.stub.location=*<NB Install Path>*/harness/nbi/stub" ... build

So all the installer panels are just the default ones. I of course can
replace the harness in the IDE folder with my own one, but it this a bug or
am I doing something wrong?

Best,
Dmitry Avtonomov
