Grails: retrieve bean from flow scope

Question

Hi,

In my Grails app, I have a bean stored in flow scope under a key that is dynamically generated. In a GSP I want to retrieve the bean. Assume that the key of the bean is the current Date as a String (though it's not really).

If in my GSP I use something like

${new Date().getDateString()}

then this will render the current date, but what I want to do is retrieve the bean from flow scope with this key.

Thanks, Don

I'm not sure how you'd do this exactly the way you state it. As you state, most times whatever variable held the key would just be converted to a string and displayed. During a WebFlow, everything below the session scope is flattened (including the request and flow scopes) and not referred to by scope-name.

Is there a reason they have to be put in the Flow scope directly? Would it still work for you if you put a Map in the flow scope called "storedBeans" or some such, and put your beans in the map using those generated keys? Then something like:

${ storedBeans[ generatedKeyVar ] }

should return the bean your interested in.
