Martin Pradny [http://community.jboss.org/people/mpradny] created the discussion "Empty string process variable on Oracle 9i" To view the discussion, visit: http://community.jboss.org/message/538936#538936 -------------------------------------------------------------- I've just moved jbpm 4.3 application form my test environment on MySQL to customer's test server which storing data in Oracle 9i. I process I'm using process variables and test them in decision nodes, eg. is there is something take one path, otherwise take different one. Problem is that when I store empty string variable in the database is physically stored null. When I try to read it back in EL I get error that variable has not been found. I have found thread discussing handling null values in EL, but this is slightly different case. If I store "" I want to get "" back. This should be completely transparent for the jbpm engine. Am I missing some configuration in hibernate? I don't want to use solution that I would store some fake value instead of empty string e.g. "$$this_is_really_empty" :^0 .
