Modules 0.1 - SWF, Hivemind and Tapestry

[jvpoucke]

Since there is a Module 0.1 released, stating:

"The HiveMind and Commons Validator support classes are considered to be stable and ready for use in production."
(see http://opensource.atlassian.com/conf...s+0.1+Released)

Does this mean we ca now configure Tapestry as a bunch of Spring Beans?
So, we could easily write a Page implementation supporting WebFlows?

This doesn't answer your question, but anyway: SWF-Tapestry integration has already been talked about, but so far hasn't been implemented yet.

Hmm, thanks for your response Erwin. Do you have any pointer on the integration (forum or somewhere else)? I might give it a try...

Jonas,

The SpringModules HiveMind support allows for HiveMind services to be accessed like Spring beans not the other way around. As I understand it, HiveMind already has support for accessing Spring beans as if they were HiveMind services so this might do want you want.

That would be excellent!

SWF itself is protocol (Servlet, Portlet, JSF, Tapestry, ...) independent to make it easy to integrate with other systems. I suggest you take a look at the Servlet integration as an example, on which you can probably build (http://www.springframework.org/docs/...e-summary.html). Basically you have to do the following:

* Create an ExternalEvent (http://www.springframework.org/docs/...rnalEvent.html) subclass that captures all required information coming into the webflow system from the client system, so probably a TapestryEvent with appropriate properties usefull in a Tapestry environment.

* Create a FlowExecutionManager (http://www.springframework.org/docs/...onManager.html) that manages flow execution from the client system, so probably a TapestryFlowExecutionManager.

* A Tapestry integration component that can drive the flow execution from inside Tapestry (e.g. it is the client of the TapestryFlowExecutionManager). As an example, take a look at the FlowAction (http://www.springframework.org/docs/...lowAction.html) that drives web flow execution from inside Struts.

I don't know anything about Tapestry, so you might need to do other stuff, but this is the basic overview.

Heel hartelijk bedankt, ik zal zien wat ik kan doen!(*)

(*) Thank you very much, I'll give it a try

I'm also very interested into the Tapestry integration...
It seems to me that the flow could be integrated only with new components:
* ExternalEvent: if I understand that well, it receives info from the client (I assume for instance info from hidden fields), then that could be implemented in a subclass of a hidden component which would store and read/use the info
* FlowExecutionManager: would plug into the same previous component that stores info in hidden field or url
* TapestryFlowExecutionManager: I think this one could be plugged into several @Form components and be a listener.

So what about subclassing the @Form component into a @SWFForm?
An obscure point is how to integrate the tapestry valid components and custom errors into the workflow?
