Ronald, thanks for responding. Regardless of whether the "otherwise" transition
should be first or last (which is just a matter of convention), the current
behavior is wrong. Here's a test case:
| package test;
|
| import junit.framework.TestCase;
| import org.jbpm.context.exe.ContextInstance;
| import org.jbpm.graph.def.ProcessDefinition;
| import org.jbpm.graph.exe.ProcessInstance;
| import org.jbpm.graph.exe.Token;
|
|
| public class TestDecision extends TestCase {
|
| public void testDecison0() {
| runProcess(0, "end");
| }
|
| public void testDecison1() {
| runProcess(1, "s1");
| }
|
| public void testDecison2() {
| runProcess(2, "s2");
| }
|
| private void runProcess(int value, String expectedState) {
|
| ProcessDefinition processDefinition =
ProcessDefinition.parseXmlInputStream(getClass().getResourceAsStream("processdefinition.xml"));
| ProcessInstance processInstance = new
ProcessInstance(processDefinition);
|
| ContextInstance contextInstance =
processInstance.getContextInstance();
| contextInstance.setVariable("myVar", new Integer(value));
|
| Token token = processInstance.getRootToken();
|
| token.signal();
| assertSame(processDefinition.getNode(expectedState),
token.getNode());
|
| }
| }
|
With this processdefinition.xml:
| <process-definition name='Test Decision'
| xmlns='urn:jbpm.org:jpdl-3.1'
| xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
| xsi:schemaLocation='urn:jbpm.org:jpdl-3.1
http://jbpm.org/jpdl-3.1.xsd'>
|
| <start-state>
| <transition to='d'/>
| </start-state>
|
| <decision name='d'>
| <transition to='s1'>
| <condition>#{myVar == 1}</condition>
| </transition>
| <transition to='s2'>
| <condition>#{myVar == 2}</condition>
| </transition>
| <transition to='end'/>
| </decision>
|
| <state name='s1'/>
|
| <state name='s2'/>
|
| <end-state name='end'/>
|
| </process-definition>
|
testDecision0 and testDecision2 fail, the task being in the s1 state in both
cases. When I put the otherwise transition at the first position, nothing
changes.
Note that if you replace the conditions with an expression, like this, all
works fine:
| <decision name='d' expression='#{ myVar }'>
| <transition name='0' to='end'/>
| <transition name='1' to='s1'/>
| <transition name='2' to='s2'/>
| </decision>
|
Regards,
Jay
