This is not a bug. Your App can have many activities and you can use a layout file from the designer in any activity or all activities. There is no way for the designer to know if you plan on using it in the first activity or the second or both.
I would hate to think that it would only generate members to the module that I first loaded the layout file in.
True
...but I can't count all the times (in the beginning) I generated numerous view-names (and events) which ended up in the wrong module which I then had to delete.
Over the time, I got used to it and it rarely happens these days.
However, a dialog-box confirming if you want to generate members or not would be great.
