Event-based gateway used wrongly

The check bpmnlint/event-based-gateway, in the group Modelling rules.

Error

Why it matters

An event-based gateway waits for the first of several events, so it needs at least two ways out and none of them may be conditional.

How to fix it

Give the gateway two or more outgoing flows to events, and remove their conditions.

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/event-based-gateway. In a terminal, penstock check --only rules reports it.

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