I have not seen the duplicate functions and variables appearing twice, how did you generate a second time with the same settings? The generate button should be disabled after the first generation, however we hope to change this in the next version so you can actually create multiple projects in a sitting. I would like to try to recreate this though, so any info would be appreciated!
Also, if you didn't see it already, a patch release 1.0.1 was put out yesterday (more detail about it here: http://devgirl.wordpress.com/2010/09/07/adobe-air-launchpad-update/).
Here's how to recreate it (and it still exists in the new version - just tested):
- Run through the settings (I chose some of the options in configuration and samples just so that those methods get generated)
- Save to location (I just chose my desktop) and generate
- Delete the files you generated, rechoose the location (desktop) and generate button is reactivated - OR - simply choose a new location and the generate button is reactivated
In that scenario it appears that any methods added in the configuration and samples selection stage are generated twice.
Hope that helps.
