[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-1073) CompositeContextEntry is raising NPE
[ http://jira.jboss.com/jira/browse/JBRULES-1073?page=all ]
Edson Tirelli resolved JBRULES-1073.
------------------------------------
Resolution: Done
Problem was a mistake in the constructor where an incorrect variable declaration was
shadowing the instance attribute:
public static class CompositeContextEntry
implements
ContextEntry {
public ContextEntry[] contextEntries;
private ContextEntry entry;
public CompositeContextEntry(final Restriction[] restrictions) {
final ContextEntry[] contextEntries = new ContextEntry[restrictions.length];
for ( int i = 0; i < restrictions.length; i++ ) {
contextEntries[i] = restrictions[i].getContextEntry();
}
}
Fixed.
