kandi X-RAY | spring-webflow Summary
Spring Web Flow facilitates building web applications that require guided navigation -- e.g. a shopping cart, flight check-in, a loan application, and many others. In contrast to stateless, free-form navigation such use cases have a clear start and end point, one or more screens to go through in a specific order, and a set of changes that are not finalized to the end. A distinguishing feature is the ability to define a flow definition consisting of states, transitions, and data. For example, view states correspond to the individual screens of the flow while transitions are caused by events resulting from the click of a button or a link. Data may be stored in scopes such as flash, view, flow, and others. Scoped data is cleared when it is no longer in scope. In REST terms a flow represents as a single resource. The same URL used to start the flow is also the URL used to step through the flow (there is also an execution key uniquely identifying the current flow instance). As a result of this approach navigation remains encapsulated in the flow definition.

Answered 2020-Oct-08 at 08:44- Delete your
web.xml
- Delete your
WebAppInitializer
- Delete your
dispatcher.xml
- Remove
@CompoentScan
from yourWebFlowConfig
- Cleanup your
AppConfig
(only leave the WebFlow configuration stuff) - Put properties in your
application.properties
- Let your
@SpringBootApplication
extendSpringBootServletInitializer
- Build and deploy.
Your AppConfig
does too much and disables Spring Boot auto-config only leave the WebFlow configuration.

QUESTION
I am working on a form with text fields and I am trying to submit the form. However after pressing submit it just leads straight back into the form. I've indicated in my flow.xml file to validate it and then if successful go to homepage, but clearly this isn't happening. There's no validation logic yet, it just succeeds no matter what. I also don't see any exceptions in the console so I suspect this is an html issue but I could be wrong. I am using spring web flow and jsp.
Code shown below:
applicationForm.jsp:

Answered 2020-Jun-19 at 19:05So I had to remove enctype="multipart/form-data"
from my form tag and it works. If someone could clarify why this matters that would be great.

I'm facing this exception, in a java 1.7 project:
...ANSWER
Answered 2020-Apr-01 at 17:02The only explanation that comes to mind is if the linked list is being passed over the wire and the sender explicitly sets its size as -1 in the payload.
Then the endpoint would try and possibly succeed in setting the size to -1 via reflection.
But is is a shot in the dark.
