Yes, do you like that better?  I think it reads cleaner: e.g on the
occurrence of this, do that.  I tried "on-event" as well, but thought it to
be verbose.

Keith,

 

I like the convenience of the terser definition of actions - it avoids the
glut of action definitions that end up in the application context, and
having to skip from the webflow definition to the app context to see what's
going on. I have wanted to be able to do exactly this a number of times.

 

Is the ''transition on=...' just a direct replacement for 'transition
event=...'?

 

-Dave

Hey guys...

 

Made some minor tweaks to the web-flow.dtd tonite, adding several new
capabilities:

 

Below is a purposefully elaborate "action state" definition illustrating the
new stuff:

 

<action-state id="actionState1">

      // execute "action1" when entered, where "action1" is the id of a
selected/exported action impl in the registry (typically a spring bean
factory)

      <action id="action1"/>

 

      // execute an instance of the action impl class when entered, impl
instantiated is delegated to registry, no attempt at autowiring

      <action
class="org.springframework.web.flow.config.XmlFlowBuilderTests$TestAction"/>

 

      // execute an instance of the action impl class when entered, impl
instantiated is delegated to registry, byType autowire policy

      <action
class="org.springframework.web.flow.config.XmlFlowBuilderTests$TestAction"
autowire="byType"/>

 

      // execute an instance of the action impl class when entered, instance
is retrieved from registry by type

      <action
classref="org.springframework.web.flow.config.XmlFlowBuilderTests$TestAction
"/>

 

      // on event "event1" transition to "viewState1"

      <transition on="event1" to="viewState1"/>

 

</action-state>

 

Aside: for those new to web-flow, an action state, when entered, executes
one or more "Action" implementations (kind of like a Controller in terms of
general responsibilities of brokering between the web-tier and middle-tier.)

 

Look OK?

 

Keith
