My app has a persistent business object model. I also have a persistent jbpm workflow which describes the status of an entities in my biz model. I need to select entities based on their workflow state and their data. E.g. A global document system where documents are approved by regional editors. I need to select all documents in the state "awaiting approval" where the document region is EU. I'm not sure of the correct approach to model this: 1) place the relevant document attributes (doc_id, region) as variables within the workflow. Search for approval workflow tasks with matching process vars - region = 'EU'. Necessitates duplication of vars between biz entity and process vars. 2) add an attribute to the doc entity (process_id). Search for approval workflow tasks, joined to biz model where doc.region = 'EU' and doc.process_id = foo. 3) place the doc_id as a variable in the workflow and query both process and biz database joined by doc_id and were doc.region = 'EU' Is there a "correct" way to achieve this?
