For a demo I'm trying to extend the websale example with a simple condition,
but am getting to feel stupid as I cannot find a way to access the value of
'quantity'...
The variable has been defined in the forms, such as form.create.xhtml, just as
provided in the sample code:
<h:inputText
| value="#{var['quantity']}"
| converter="javax.faces.Integer"
| converterMessage="The quantity must be numeric."
| validatorMessage="The quantity must be at least 1.">
| <f:validateLongRange minimum="1"/>
| </h:inputText>
In procesdefinition.xml I'm trying:
<decision name="Large quantity?">
| <transition name="No" to="ship item">
| </transition>
| <transition name="Yes" to="Make appointment">
| <condition expression="#{contextInstance.variables['quantity'] gt 10}">
| </condition>
| </transition>
| </decision>
Of course I tried many other ways, including "#{var['quantity'] gt 10}", CDATA,
and even comparing string values. No matter what, I keep getting:
org.jbpm.graph.node.Decision
| decision didn't select transition, taking default Transition(No)
When also adding this specific variable to a controller then the value as
entered in the task form (jbpm-console) is not preserved (not shown in the next
forms), so that does not seem to be the correct way to do things either:
<start-state name="Create new web sale order">
| <task swimlane="buyer" >
| <controller>
| <variable name="quantity" mapped-name="quantity"></variable>
| </controller>
| </task>
| <transition to="Evaluate web order" />
| </start-state>
I know I can delegate the decision to a Java class, but if I understand
correctly than the above should really not be too hard to achieve at all,
right...?
Thanks for any hints!
Arjan.
