[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1220) Integration with jBPM does not work
[ http://jira.jboss.com/jira/browse/JBRULES-1220?page=comments#action_12380802 ]
Mark Proctor commented on JBRULES-1220:
---------------------------------------
Have you verified the global resolver it is using is the jbpm one, and that it hasn't
lost the configuration and gone back to the drools default?
Integration with jBPM does not work
-----------------------------------
Key: JBRULES-1220
URL: http://jira.jboss.com/jira/browse/JBRULES-1220
Project: JBoss Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 4.0.1
Reporter: Jiri Pechanec
Assigned To: Mark Proctor
Priority: Minor
Fix For: 4.0.2
We had a code that intgrates JBoss Rules Global Resolver with jBPM variable pool
workingMemory.setGlobalResolver(new GlobalResolver() {
private static final long serialVersionUID = 1L;
public Object resolveGlobal(String identifier) {
System.out.println("!!!!!!!!!! resolve " + identifier);
return ci.getVariable(identifier);
}
public void setGlobal(String identifier, Object value) {
System.out.println("!!!!!!!!!! set " + identifier);
ci.setVariable(identifier, value);
}
});
And a rule file that serves as test
package org.jbpm.action
import org.jbpm.resolveraction.Customer;
import org.jbpm.resolveraction.Order;
import org.jbpm.context.exe.ContextInstance;
global java.lang.String shipper
rule "Determine Shipper"
when
Customer( region >= 1 )
Order( totalAmount >= 0 )
then
System.out.println(shipper);
drools.getWorkingMemory().setGlobal( "shipper", "FEDX" );
System.out.println("ship via FEDX " );
end
The output of the test is as expected
11:50:51,226 INFO [STDOUT] !!!!!!!!!! resolve shipper
11:50:51,227 INFO [STDOUT] None
11:50:51,227 INFO [STDOUT] !!!!!!!!!! set shipper
11:50:51,227 INFO [STDOUT] ship via FEDX
But if we modify the rule file to
package org.jbpm.action
import org.jbpm.resolveraction.Customer;
import org.jbpm.resolveraction.Order;
import org.jbpm.context.exe.ContextInstance;
global java.lang.String shipper
rule "Determine Shipper"
when
eval ("None".equals(shipper))
Customer( region >= 1 )
Order( totalAmount >= 0 )
then
System.out.println(shipper);
drools.getWorkingMemory().setGlobal( "shipper", "FEDX" );
System.out.println("ship via FEDX " );
end
then nothing is printed - no attempt to resolve shipper global variable
