Conditional flow without a condition

The check bpmnlint/conditional-flows, in the group Modelling rules.

Error

Why it matters

A flow that leaves a task or event marked as conditional but has no condition either always or never fires; the engine cannot tell.

How to fix it

Give the flow a condition, or make it an ordinary flow.

Where you see it

The editor puts a marker on the element while you draw, and the Problems tab of the sidebar lists it under Rules, with the rule name bpmnlint/conditional-flows. In a terminal, penstock check --only rules reports it.

To change how strict this rule is, set conditional-flows to error, warn or off in your .bpmnlintrc. See Validation.
