[Webwork-devel] action chaining

[Matt B. <ma...@sm...>]

I think I'm ready to go ahead and implement action chaining feature. If you
are interested in the discussion, you can visit the thread below. I'll get
this done and committed soon for others to comment and test drive it. Thanks
to Pat, Jason, and Aapo for their discussion contributions. You gotta like
JIRA :).

[Webwork-devel] action chaining

[<ma...@sm...>]

I implemented a preliminary version of action chaining.
It is available in CVS with a simple test case. This
has not been extensively tested so *beware*. I'm
looking for early testers.

The basic logic is the following:

1. Setup your chain in your view mapping.
2. The dispatcher will walk the chain as long as each
action returns another alias action. This will continue
until a non-action, usually a view, is returned.
3. Each action will first be set via the context and
then the previous action's attributes will be copied to
the current action if applicable.

Enjoy!

Matt,
This doesn't appear to be working for cases such as the follow (which I used
extensively before action chaining, and i thought it would still work now
too, but maybe not):

Details.action=paws.Details
Details.success=details.jsp

EditMetadata.action=paws.metadata.EditMetadata
EditMetadata.error=edit.jsp
EditMetadata.success=Details.action

EditMetadata and Details both extends AbstractPAWSAction, which looks like
this (get/set for the following):

id
title
language
creator
...etc

EditMetadata and Details both don't have any extra properties worth
mentioning in this example. Now EditMetadata.doExecute() is called and
returns SUCCESS, but then the browser gets a blank page at
http://localhost/paws/csh/EditMetadata.action and the console shows this
error:

java.lang.IllegalArgumentException: No error view found for action Details
        at
webwork.dispatcher.ConfigurationViewMapping.getView(ConfigurationViewMapping
.java:87)
        at
webwork.dispatcher.ConfigurationViewMapping.getView(ConfigurationViewMapping
.java:85)
        at
webwork.dispatcher.CachingViewMapping.getView(CachingViewMapping.java:47)
        at
webwork.dispatcher.DefaultViewMapping.getView(DefaultViewMapping.java:35)
        at
webwork.dispatcher.ServletDispatcher.getView(ServletDispatcher.java:336)
        at
webwork.dispatcher.ServletDispatcher.service(ServletDispatcher.java:258)

I added "Details.error=details.jsp" and instead of getting the error, I got
returned to details.jsp just fine, except that all the properties were null
so errors were all over the place. Any idea what's going on here?

-Pat

[Webwork-devel] Have your say in WW devel

[Mike Cannon-B. <mi...@at...>]

FYI (I'm not sure if everyone has found this yet) you can vote on issues
that you'd like completed, see:

http://opensource.atlassian.com/projects/webwork/secure/BrowseProject.jspa?i
d=10000&report=popular

Clearly currently chained actions and better documentation are the two most
important things - if you don't think so, vote for what you want.

This sort of list helps the ww developers (who I'm sure only have a limited
amount of time like the rest of us!) know what is most important to the most
amount of people.

Enjoy.

Yup, JIRA is very nice to help with project management. Makes sure you don't
forget stuff, which is easy in this open source world :)

I've asked Mike to enabled reply-by-email comment support on the opensource
JIRA instances (WebWork and OpenSymphony) so that discussion is even easier!
