Pradeep Kamath updated PIG-336:
-------------------------------

    Description: 
The following code currently does not work
{code}
B = filter A by $0 is null and $1 is null;
{code}

Some other things which don't work with nulls include POAND, POOR etc


  was:
The following code currently does not work
{code}
B = filter A by $0 is null and $1 is null;
{code}



        Summary: NULL checks are not in place in the types branch  (was: is null does not work in a AND)

I am currently working on adding null in data for unit test cases so that testing with nulls is part of unit test cases. I am also trying to fix code issues along the way - will have a bigger patch once done.
