NPE when reading a process definition with a decision name which contains the
"/" character

Key: JBPM-1686

Project: JBoss jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: jPDL 3.2.2
Environment: JDK1.6.0, Eclipse 3.3
Reporter: Julien Kronegg
Priority: Minor
When a process definition is read and when it contains a decision named with a
"/" character, a NullPointerException is raised:
import org.jbpm.graph.def.ProcessDefinition;
public class TestDecisionNPE {
public static final void main(String[] args){
ProcessDefinition.parseXmlString(

" <transition name='three' to='c'>" +
" <condition>#{a == 3}</condition>" +
" </transition>" +
" </decision>" +
" <state name='a' />" +
" <state name='c' />" +

This is due to a "node = nodeCollection.getNode(namePart);" in
ProcessDefinition.findNode(): a Decision has no nodes, so the nodeCollection is null.
It should be :
1. a more descriptive exception message, such as "could not get the node with name
XXX"
2. a validation step which prevent the node name to contain "/" characters, e.g.
throw an exception "the node name cannot contain a "/" character"

----------------------------------------
Thomas, your changes broke the build. Nodes should accept null as a valid name. I've
fixed that and excluded JBPM2036Test as well because it causes regressions.
