  Hi Levi,

  Firstly, I'd like to tell you that it's a rare event to find someone who actually recognises a term like "stripped-down example", let alone one whose code is complete enough to demonstrate the issue without any hacking and emulator restarts. Even though I was ready to close down for the night, I was so surprised, that I started everything up again! :)

  And now I have just noticed that you have even tagged it correctly with your target platform! I want to vote your post 1000 times so that everyone sees the fine example that it sets! ;)

  I can see that you have the right idea with your code, but the problem is that you cannot add a window to a view. Conversely, you can add a view to a window. I could immediately see a description of the problem when I ran your code because I was running android's adb -e logcat to see logging messages, which showed:

  java.lang.IllegalStateException: call to getView on a Window
  

  Obviously that's not an option for you when working with the apple's sdk, but you could use the
  TiDev Run Emulator screen and set the filter at the bottom to "Trace".

  So, replace the last 4 lines of your code with the following and it will work.

  view1.add(btn1);
  win1.add(view1);
  win1.open();
  

  However, I am mindful that this won't give you your original intended result. Would you have a look at it again, with the information about adding views in mind, and if you need further help, let me know what you are aiming for and I will help you through it.

  Good luck, and enjoy it!

• I just had a similar trouble, so I'd like to to add that adding a window to a window will lead to the same exception :

  java.lang.IllegalStateException: call to getView on a Window
  

  So you have to remind that you can nest views but not windows.
