Render JSON as result of webflow execution (expression evaluation).

[mauro_monti]

Hi Guys,

Quick question. I am working with webflow in an application and I need to render JSON as result of an evaluation expression.

My flow is defined in this way

<view-state id="..." view="...">
 <transition on="paginate">
            <set name="requestScope.echo" value="requestParameters.sEcho" type="int" />
            <set name="requestScope.startIndex" value="requestParameters.iDisplayStart" type="int" />
            <set name="requestScope.pageSize" value="requestParameters.iDisplayLength" type="int" />

            <evaluate expression="dashboardFlow.requestPage(requestScope.echo, requestScope.startIndex, requestScope.pageSize, flowScope.application, flowScope.statuses)" result="flowScope.result"/>
        </transition>
</view-state>

Is there any way to tell webflow to render the result of this expression evaluation?

I was trying to setup the ContentNegotiatingViewResolver to use jackson, but I cant find a way to tell webflow to serialize or render an specific result.

How do you solve this cases? What approach should I use?

Thanks!.

Maybe using: http://static.springsource.org/sprin...eaming-actions ?
Which approach is the best for these cases?

I was taking a look to a lot of examples and all of them use the approach to render fragments (html fragments) but i need to return a Serialized object.
Thanks!
