NumberFormatException＆amp; Activiti Explorer中的NullPointer异常

时间：2015-01-15 19:18:14

标签： activiti bpm bpmn

每当我点击Activity Explorer中的Processes或Reports选项卡时，它会显示“Internal Error，Please notify administrator”，我在控制台中收到以下错误。

尝试在activiti论坛中搜索一些类似的错误，但没有解决方案。

任何人都可以帮我吗？

看起来像是vaadin bug http://dev.vaadin.com/ticket/9115， 尝试更新vaadin版本。

如果有人再次遇到问题： https://forums.activiti.org/content/activiti-explorer-runs-return-error#comment-35300

一种可能的解决方案是在web.xml文件中设置servlet过滤器，以便为http响应添加一个X-UA-Compatible标头。 根据这篇文章https://dev.vaadin.com/ticket/12635，另一种补救方法是将Vaadin升级到6.8版本。
