I have multiple features a user can install. I have configuration,including panels to prompt for that info. I need to only prompt and configure if the user has selected that feature. I can't find an easy way to do this. There should just be one variable I can check. I think this is something everyone would need... shouldn't it be a standard rule? Am I missing something?
I think the solutions is to write a custom rule that cycles through CHOSEN_INSTALL_FEATURE_LIST looking for the feature. I just can't imagine that it is not a given.
Instead of looping over the values in a custom rule, perhaps use a Compare InstallAnywhere Variables rule that checks if $CHOSEN_INSTALL_FEATURE_LIST$ contains the feature name you want? Assuming the feature names don't overlap (no case like "thing" and "nothing", and all that)...
