  • _flowExecutionKey is shown as null

    Hi,
    WE are using Spring WebFlow RC version in our project.
    We have already developed a wizard-application using it.

    Now, in the current requirement, the problem we are getting is as below:

    We have a View-State as the start-state with a entry-action class method.
    In this action class, we are not getting the value of "_flowExecutionKey".
    Following is showing the value as null.

    String key = context.getExternalContext().getRequestParameterMa p().get("_flowExecutionKey");
    System.out.println("key..."+key);

    For wizard to work correctly, the value of this key is must.
    Please help in solving this.

    Thanks.

    It's normal that there is no _flowExecutionKey request parameter in the request that launches the flow (the first request). That request will cause the FlowExecution to be created and assigned a key to be stored in the repository.

    I would also advise you to try to upgrade to SWF 1.0.1.

      It is my mistake.

      As pointed out by Erwin, _flowExecutionKey request parameter is NOT created in the request that launches the flow (the first request).

      Thanks.
