Question

Answer 1

1. Please look in the Error Log view in Eclipse; there should be an exception trace there which could help us in identifying the root cause.

2. Can you reproduce this? Does it happen only when you create a new project and add all Mobile environments at once, or even when you add only one Mobile environment?

3. What is your Worklight version?
