我尝试了使用 BonitaBPMCommunity-7.3.1-Tomcat-7.0.67链接http://community.bonitasoft.com/project/process-variable-example给出的简单流程变量示例。它在 bonita studio 和默认的 h2 数据库配置和 tomcat 包中运行良好。但是当我用 PostgreSQL 数据库配置 tomcat 包时，它不能很好地与 Bonita ui 表单一起使用，但可以很好地与包含 6.x 表单的进程一起使用。我已按照官方链接http://documentation.bonitasoft.com/?page=tomcat-bundle中给出的数据库配置说明进行操作. 使用 bundle 配置 PostgresSQL 时，日志文件中没有错误。这种行为是因为我在 Windows 7 Ultimate 32 位上运行 tomcat 包“BonitaBPMCommunity-7.3.1-Tomcat-7.0.67”？如果我问了一些愚蠢的问题，我是 Bonita 的新手，请原谅。
