the test case is failing for me.

The pull request for based on 2.1.0-beta-incubating-SNAPSHOT, however this version is no longer available in repo. There are two changes that needs to be done to make it work:

1. set the lens dependency as 2.2.0-beta-incubating-SNAPSHOT
2. Merge the fix for JIRA LENS-549 in lens.

I'll be sending the patch for LENS-549 today. Once its available then I'll fix this patch to point to newer Lens version.

Travis CI logs suggest that the failure is not cause of my changes. Its failing cause of selenium test issue.

Current master branch has some problem with automated test.
#88 includes fix for the problem.

You can rebase this branch and see if CI passes after #88 is merged.

After rebasing with apache master, I was getting issues in pushing the changes. I then took a easy route and created a new pull request -> #100.
