If you're using a distribution, you could attach a custom JavaScript
requirement to a choice that represents a package.
It would look something like
function preventDowngrade()
{
if (choices.installer_choice_X. packageUgradeAction== downgrade)
return false;
return true;
}
Now, to figure out what X should be, you just need to know that the
choices id created by Packages are based on their indentations.
So if you have the following choice hierarchy
group
choice A
choice B
choice C
The IDs will be:
installer_choice_1
installer_choice_1_1
installer_choice_1_2
installer_choice_2
