Worked on enhancing the BPMN integration documentation within the jmix-framework/jmix-docs repository, focusing on clarifying the requirements for injected field types in BPMN service tasks. The update specified that injected fields must use the org.flowable.common.engine.api.delegate.Expression type, reducing the risk of misconfiguration for developers integrating BPMN workflows. This documentation-only change, implemented using adoc and leveraging strong documentation skills, aimed to improve onboarding and accuracy for users. No code changes were required, as the work centered on refining technical content to address common integration issues and streamline support, ultimately contributing to a smoother developer experience with BPMN service tasks.
