JPDL: Multiple actions on transition or page?

patrickr Aug 23, 2007 5:41 PM

Hi,

according to the pageflow-2.0 schema this is valid:

<start-page name="Address" view-id="/pages/checkout/address.xhtml">

 <action expression="#{flowUtil.test}" />
 <action expression="#{flowUtil.test2}" />

 <transition name="next" to="End">
 <action expression="#{action1.test}" />
 <action expression="#{action2.test2}" />
 </transition>

</start-page>

However, only the first action is called. Is this a bug? I would love to chain multiple actions, because then I could plug in more actions without any dependencies.

This appears to be allowed by JBPM

http://docs.jboss.com/jbpm/v3/userguide/jpdl.html#transition.element

N.B. Pageflows are just a special kind of JBPM process.

So, should I add a feature request / bug issue?

To clarify my motivation behind this, please refer to the following code:

<transition name="next" to="End"> <action expression="#{database.persist(order)}" /> <action expression="#{mailer.sendConfirmation(order, user)}" /> </transition>

Consider the mailer service might have been added to the project at a later time. I can plug this component in without writing or compiling code. It is loosly coupled and is not transparent like aop approaches (which is what I want, because it's not a cross cutting concern and developer can see / debug this component easily...) - not cool? ;-)
