Flowscope outside Spring Web Flow

[Arun Prasath]

Hi,

I am using Spring Web Flow 2.0. Could anyone please let me know how to access flow scoped variables outside spring web flow, may be in servlet, filter or mvc controller ?

I tried to use flow execution key to get the FlowExecution from flow repository, but it always returns null, which I found found here, http://www.ervacon.com/products/swf/tips/tip1.html. But, It does not seem to be working.

Please help to solve this !.

Could anyone clarify my question ?

Looks like there are some thread bound context holder classes

ExternalContextHolder and RequestContextHolder

I am not sure if these will help you or not.

import org.springframework.webflow.execution.RequestContext;
import org.springframework.webflow.execution.RequestContextHolder;

RequestContext requestContext = RequestContextHolder.getRequestContext();
requestContext.getFlowScope();

Alternatively if you have an evaluate action you can pass it in, and have your Controller method accept a RequestContext.

<evaluate expression="myController.someMethod(flowRequestContext)"/>
