The condition associated with a connector coming from a Decision gateway uses Java operators that include “&&” for AND and “| |” for OR. The expression reads from left to right and can be as long as required. Only user-defined dataslots can be used as the variables.
BPM Designer also provides expression validation: that means, expressions are checked and validated at design time, not at runtime. Application developers are notified of any errors in the expressions and can correct the errors before executing the application.
