Springframework webflow變量類名稱未找到

我有彈簧webflow變量的初始化問題。我有兩個流xml的，他們看起來相同，但是當打開其中一個彈簧引發這個異常。在流動有兩種類型的變量初始化：Springframework webflow變量類名稱未找到

<var name="bean" bean="beanName" scope="flow" />

和

<set attribute="id" value="${'someId'}" scope="flow" />

這裏是例外：

我不知道你正在嘗試做的，但如果你想使用<var>元素你需要需要名稱和類屬性。像 <var name="myVar" class="com.example.var.MyVar"/>

加，你就不需要在wefblow定義豆，你可以使用自動在ApplicationContext中

我解決問題中定義的。問題出在webflow方案版本不匹配。我的一個流xml使用1.0，而系統使用2.0。
