Re: Stateless form.processForm

Hello

Do you have main_template.xml in your main-display-pipeline? Perhaps  
is is enough to define your form template without continuation, like  
<ft:form-template action="xxx" method="POST">. Also perhaps you don't  
need any processing in flow.js after form.showForm("main-display- 
pipeline", data).
