Question

I've inherited an application that is currently using Webflow 1.0.6 and am attempting to upgrade this to Webflow 2.3.4 as an interim step before upgrading to a later version.

I've run one of the flows through the WebFlowUpgrader and it has produced the below output:

I'm unsure how to resolve the warning WARNING: the bean attribute is no longer supported

Prior to the running through the WebFlowUpgrade upgrade the variables were declared as:

    <var name="ControllerHelper" bean="ControllerHelper" scope="flow" />
    <var name="ListStructureDataController" bean="ListStructureDataController" scope="flow" />
    <var name="ViewElementDetailController" bean="ViewElementDetailController" scope="flow" />

尝试使用class：

<webflow:var name="ControllerHelper" class="com.example.ControllerHelper">
