2 posible transitions for 2 different roles
Hello, i'm reading the docs but i can't see if, being in 1 state and having 2 possible actions (transitions to make), it's possible to be performed by 2 different roles.
The reason why jBpm sticks to UML-activity-diagrams is for easy-acceptance. Petri nets are easy, but not as easy and widespread as UML-activity-diagrams.

开始的时候丝毫没有意识到是这里出了问题,还以为是xsl文件中引用的uri出了问题(因为上面那个异常导致了xalan编译xsl样式表的时候无法找到import的locale.xsl文件,于是编译器又报了locale.xsl中定义的变量找不到的错误,就是这个错误误导了我好长时间而没有发现错误的源头),修改了好半天的xsl文件都没发现有问题,而且用xalan
最近在网上看到一篇N. Alex Rupp写的“Beyond MVC: A New Look at the Servlet Infrastructure”文章,意思大致是说MVC被Struts等框架错误地应用到了Servlet架构中。我想只有对Struts有足够的了解再加上在MVC方面有足够深的功力,才敢发此言论,不是经常听人说:最熟悉自己的人是你的敌人。本人功力尚浅,没有引领风潮的能力,而且生活还得继续,只能先来熟悉熟悉Struts。
申明: 强烈建议在阅读本文之前先阅读一下N. Alex Rupp老兄的文章,如果你赞同他的看法,可能你会觉得研究Struts就没什么意义了。
