not able to get the flow scope variable from one s

Question

When I transit from view state to decision state or action state all the input set is lost while transitioning to another state. How to do I get the flow scope variable for decision state or action state on transitioning from view state to decision state and action state in junit ?

In my flow definition right now I am in view state when I set the event Id as submit it moves to registerEnroll decision state where it needs flowScope.regform.loyaltyLookUp value. When I see the flow execution variable map there is nothing inside apart from RegForm object, even though I have set variable in MutableAttributeMap.

How to set the flow scope variable which will be always available on transitioning to state on junit test case for spring webflow?

In second test case flow is going to else part of decision state even though I have provide flowScope.regform.loyaltyLookUp in input. What mistake I am doing I am not able to figure out .

Answer 1

you are setting this property:

input.put("enrollresponse.responseCode", "200");

but:

1. I don't see it anywhere in your flow (maybe in the part you omitted)
2. You have to first create the enrollresponse object before setting "responseCode" on it. I think that is causing the error you are having

[EDIT]

3. you also need to specify the scope for variable in <set> element (showrror state). replace:

   <set name="errorCode" value="flowScope.enrollresponse.responseCode" />
   

   by

   <set name="viewScope.errorCode" value="flowScope.enrollresponse.responseCode" />
   

fix all those issues and try again
