在 Grails 上使用插件 Activiti 启动 VacationRequestSampleApplication 时出错

发布于 2024-12-22 10:40:44 字数 937 浏览 2 评论 0原文

我是 BPM 新手，我尝试在我自己的 Grails 应用程序上安装 Activiti。

我已经安装了插件和安全插件（Spring security 和 Activiti-spring security），以及 Vacation Request 应用程序。

来自：http://code.google.com/p/grails-activiti -plugin/wiki/VacationRequestSampleApplication

我登录了，当我单击“开始”链接时，出现此错误：

java.lang.NullPointerException: Cannot get property 'id' on null object
    at ActivitiGrailsPlugin$_addActivitiMethods_closure7_closure29.doCall(ActivitiGrailsPlugin.groovy:130)
    at ActivitiGrailsPlugin$_addActivitiMethods_closure7.doCall(ActivitiGrailsPlugin.groovy:126)

原文

I'm new on BPM and I tried to install Activiti on my own Grails application.

I've installed the plugin and the security plugin (Spring security and Activiti-spring security), and also the Vacation Request application.

From : http://code.google.com/p/grails-activiti-plugin/wiki/VacationRequestSampleApplication

I logged in, and when i click on Start link, I got this error :

java.lang.NullPointerException: Cannot get property 'id' on null object
    at ActivitiGrailsPlugin$_addActivitiMethods_closure7_closure29.doCall(ActivitiGrailsPlugin.groovy:130)

我已按以下顺序安装了插件

activiti-5.8.2
spring-security-core-1.2.7.2
activiti-spring-security-0.4.6
install-vacation-request-sampleapp

我得到

| Error 2012-03-26 11:07:49,216 [http-bio-8080-exec-10] ERROR errors.GrailsExceptionResolver  - NullPointerException occurred when processing request: [GET] /test3/vacationRequest/start

它是否来自我的插件版本使用？

I have installed plugins in following order

activiti-5.8.2
spring-security-core-1.2.7.2
activiti-spring-security-0.4.6
install-vacation-request-sampleapp

And I am getting

Can it be from version of plugins I am using ?

我没有遇到你所报告的问题。

我使用以下命令创建项目：

grails create-app a581
grails install-plugin activiti
grails activiti-quickstart
grails install-vacation-request-sampleapp

我想您可能会错过一些步骤。您可以尝试在您的工作站中运行我创建的项目，网址为 http://grails -activiti-plugin.googlecode.com/files/a581.zip

I didn't face the problem reported by you.

I create the project with the following commands:

grails create-app a581
grails install-plugin activiti
grails activiti-quickstart
grails install-vacation-request-sampleapp

I guess you may miss some steps. You may try to run the project created by me in your workstation at http://grails-activiti-plugin.googlecode.com/files/a581.zip
