org.jbpm.graph.def.DelegationException: actor-id expression '#{starter}' did

上传流程定义的报错

org.jbpm.graph.def.DelegationException: actor-id expression '#{starter}' didn't resolve to a java.lang.String: '1' (java.lang.Integer)

 

这个错真的让人纠结啊！竟然是jbpm的。。。。。问题

后面一个参数是Object的,但是这个样子写就错了。

 processInstance.getContextInstance().setVariable("starter",
    request.getSession().getAttribute("userid"));

 

modifiy 下面就行了

 

 processInstance.getContextInstance().setVariable("starter",
    request.getSession().getAttribute("userid").toString());
