Re: Shark 1.1 getting SubFlow Process

Hi, 

yes, this is a bug in BaseIteratorWrapper class.

The bug fix would be to initialize queryExpression to empty string:

protected String queryExpression="";

and to add line:

if (queryExpression==null) queryExpression="";

after line

queryExpression = query;

in method:

public void set_query_expression (SharkTransaction t,String query) throws BaseException, InvalidQuery


Regards,
Sasa.
