<div if="${Cur.viewer != null}"> is what you need. Since viewer is not
available, you have to use Cur to refer to it.
Bit offtopic,
Here's a little debugging tip that would help you see the data that os-data
section generates.
- Open the application iframe in a new tab
- Remove parameter sanitize=1 and reaload
- view source of frame.
- You'll find a opensocial.data.DataContext.putDataSet( which has the result
of evaluation of os-data section
Let me know if above doesn't work for you.
