Null pointer exception, empty alphabet size

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Open DUALIST in Exploration Mode
2. Select single lines (or tweets) data set (example attached)
3. Fill in class labels (in this case: "Pos, neg, neu"))  and press "Start 
Exploring!".

What is the expected output? What do you see instead?
Expected output is DUALIST GUI, instead see Play exception report (attached)

What version of the product are you using? On what operating system?
Lastest version of DUALIST OS X 10.7.2, Google Chrome

Please provide any additional information below.
I've tried this with two single lines datasets, one with instance numbers and a 
classification followed by the instance (separated by tabs) and the one 
attached, both result in the same error.

Using the same data set but split in to folders as a zip will work.

Hi Zack, I believe this is fixed in the current SVN branch. This reminds me, I 
need to push out a new release with these fixes. Thanks!
