Can I Specify an "A or B" condition in the Split Condition Settings?

Question.

Can I specify an "A or B" condition in the Split condition settings?

Answer.

It is possible to not only specify AND conditions (i.e. C and D) but also OR conditions like A or B.

On the [Split] tab of a Human Task, you can arrange multiple AND conditions by clicking on [+] to add them.
If you want to arrange multiple OR conditions, add multiple conditions that have the same destination Node specified. If two conditions are specified as "destination X if condition A" and "destination X if condition B" respectively, the condition is evaluated as "destination X if condition A or B". (Conditional expressions are evaluated in order from top to bottom.)
