Subject Re: [discuss] Writing WebWork actions
Date Wed, 25 Oct 2006 19:46:23 GMT
I also bounced this off of a couple other people over the last day or to..

there seems to be a general consensus from folks that I talked to that
its a good idea to try and group all the CRUD (Create, Read, Update,
Delete) actions on objects grouped into a single action.

On that note, it would be good to standardize the method names as
well, perhaps to:

public String add() {}
public String update() {}
public String view() {}
public String remove() {}

Then we would have the decision of the xwork.xml which could have
actions for each of these methods on the class, like

<action name="addFoo" class="continuum-foo" method="add">

or on the jsp's we could just use the shortcut of <ww:form action="foo!add">

how does this grab folks?   I think this is a valuable step in things
since it will give us a chance to audit all of the actions, improve
the -webapp project for contributors...and -webapp is a great place
for people to start with continuum...and it will also serve as a good
swift kick towards finishing off the testing work that emmanuel will
be committing soon.
