Issue #69

[SaiUpadhyayula]

Fixed NullPointer Exception when clicked on Cancel button in the FileDialog

[rohitvvv]

Please add a unit test.

[SaiUpadhyayula]

As the application is using the Native OS File Dialog for the file upload, it seems we cannot test this functionality through TestFX.

Hence I added a unit test for the null check.

Please check.

can u check the build failures?

[SaiUpadhyayula]

I think the build errors are due to the new dependencies in the previous PR below #67 (comment)

The dependencies are downloaded without any problem and the build is fine on my Local.

Should we change anything in the Travis CI ?

[jbuddha]

have u tried clean install

[rohitvvv]

It seems travis build is unable to resolve Loggable annotation.

[SaiUpadhyayula]

Yes, the Clean Install is fine on my machine.

[rohitvvv]

Merging for now as the build is clean.
