BPMN Modeler

A Flowable-based BPMN 2.0 modeler. It authors *.bpmn process definitions that the embedded Flowable engine executes at runtime.

Files

• *.bpmn - BPMN 2.0 XML. Reconciled by BpmnSynchronizer and deployed to the Flowable engine.

Authoring

Drag stencils from the palette onto the canvas.

• Events - start, end, intermediate (timer, message, signal, error, escalation), boundary.
• Activities - user task, service task, script task, send task, receive task, manual task, business rule task, call activity, sub-process.
• Gateways - exclusive, parallel, inclusive, event-based.
• Sequence flows - with optional condition expressions.
• Pools and lanes - participant decomposition.

Selecting an element opens the property panel on the right. Each stencil exposes its own set of properties (id, name, documentation, assignments, listeners, async / compensation flags, ...).

Service-task handlers

Service tasks invoke handler code. Set the handler from the property panel's Assignments editor:

• JavaScript / TypeScript - delegate expression ${JSTask} plus a handler field whose string value is the path to the JS/TS file (e.g. my-project/handlers/MyHandler.ts).
• Java - delegate expression ${JavaTask} plus a handler field whose value is the fully-qualified Java class name. The class must implement org.flowable.engine.delegate.JavaDelegate and is compiled by engine-java. The ${JavaTask} form is hot-reload-safe. The alternative flowable:class="..." binding works but pins the first generation of the class until restart.
