Error description
In a ruleflow if you happen to let an empty ruletask subflow ( no ruleflow referenced), this will fail to generate a ruleset ( compile ) producing NullPointerException in the workspace .metadata/. log : !MESSAGE An error occurred during the export of the ruleset archive. !STACK 0 java.lang.NullPointerException at com.ibm.rules.engine.ruleflow.compilation.

Local fix
Fill out the subflow, with a reference to an existing ruleflow.
Problem summary
The code corresponding to an empty subflow is incorrectly generated and null object are created leading to the exception.
Problem conclusion
The code is fixed
Temporary fix
