by Diego Lopez Leon (JIRA)

Missing jpbmContext.save on StartProcessInstanceCommand ------------------------------------------------------- Key: JBPM-1876 URL: https://jira.jboss.org/jira/browse/JBPM-1876 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Core Engine Environment: Revision 2990 Reporter: Diego Lopez Leon Priority: Minor On org.jbpm.command.StartProcessInstanceCommand is missing a last call to jbpmContext.save(processInstance) after the signal. One symptom of this is the loose of logging. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1244) hardcoded keys for standard definitions map in class ProcessDefinition

by Hauke Rabe (JIRA)

hardcoded keys for standard definitions map in class ProcessDefinition ---------------------------------------------------------------------- Key: JBPM-1244 URL: http://jira.jboss.com/jira/browse/JBPM-1244 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Reporter: Hauke Rabe in case you replace the "resource.default.modules" to define different definition classes, such as #org.jbpm.taskmgmt.def.TaskMgmtDefinition .........jbpm.taskmgmt.def.ExtendedTaskMgmtDefinition (extends TaskMgmtDefinition) ProcessDefinition#addDefinition(final ModuleDefinition moduleDefinition) uses the classname as definition map key, but for example the accessor ProcessDefinition#getTaskMgmtDefinition() uses hardcoded TaskMgmtDefinition.class as key. conclusion: the defined ExtendedTaskMgmtDefinition instance must use the TaskMgmtDefinition.class as key. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1206) ActionLog, SignalLog and TransitionLog hibernate mapping incorrect

by pieter martin (JIRA)

ActionLog, SignalLog and TransitionLog hibernate mapping incorrect ------------------------------------------------------------------ Key: JBPM-1206 URL: http://jira.jboss.com/jira/browse/JBPM-1206 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: linux, jboss 4.2.2 Reporter: pieter martin When calling SignalLog.getChildren() it is always null. After some investigation I noticed that SignalLog extends CompositeLog in the java class and ProcessLog in the hibernate mapping files. i.e. in SignalLog.hbm.xml extends="org.jbpm.logging.log.ProcessLog" After editing the hibernate mapping file SignalLog.getChildren() returns the children. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1867) The sql install script for mysql is not correct.

by John Wooten, Ph.D. (JIRA)

The sql install script for mysql is not correct. ------------------------------------------------ Key: JBPM-1867 URL: https://jira.jboss.org/jira/browse/JBPM-1867 Project: JBoss jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Installer Affects Versions: jBPM 3.3.0 GA Environment: MAC OS X 10.5.5, JBoss 4.2.2 GA, JBPM 3.3.0GA Reporter: John Wooten, Ph.D. When asked to select a persistence mechanism for the jbpm installation, and one chooses mysql, it isn't clear what needs to be changed. After discovering that, ( though searching the forums ), you learn to create a database in mysql, then select that database and run the installer script located in the installation. However, it fails as there are no ';' (semi-colons) at the end of each statement. For my version of mysql, making those changes at least does not through an exception while trying to log in. It still does not allow login, but I think I've found that there are no default users(admin,user,manager, cookie-monster, etc.) in the install script. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1169) NPE in org.jbpm.graph.node.Decision.execute() when using transitions with null conditions migrated from JBPM 3.0

by Julien Kronegg (JIRA)

NPE in org.jbpm.graph.node.Decision.execute() when using transitions with null conditions migrated from JBPM 3.0 ---------------------------------------------------------------------------------------------------------------- Key: JBPM-1169 URL: http://jira.jboss.com/jira/browse/JBPM-1169 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: win2000, JBPM 3.2.2, Jboss 4.2.2, Eclipse Europa 3.3 Reporter: Julien Kronegg Assigned To: Tom Baeyens A NullPointerException is raised by org.jbpm.graph.node.Decision.execute(ExecutionContext) if the table JBPM_DECISIONCONDITIONS row has null EXPRESSION_ field. The following conditions must meet: 1) initially, the user has a JBPM database in version 3.0 and a decision with conditional transitions 2) one of the conditional condition is cleared, which leads to setting the field EXPRESSION_ to null in the database 3) the JBPM database migrated from 3.0 schema to version 3.2 Note: the JBPM 3.2 database is (almost?) the same as the version 3.1, so the bug should also occur in version 3.1 (not tested). The exception is: Exception in thread "main" org.jbpm.graph.def.DelegationException at org.jbpm.graph.def.GraphElement.raiseException(GraphElement.java:387) at org.jbpm.graph.def.GraphElement.raiseException(GraphElement.java:378) at org.jbpm.graph.node.Decision.execute(Decision.java:148) at org.jbpm.graph.def.Node.enter(Node.java:319) at org.jbpm.graph.def.Transition.take(Transition.java:151) at org.jbpm.graph.def.Node.leave(Node.java:394) at org.jbpm.graph.node.StartState.leave(StartState.java:70) at org.jbpm.graph.exe.Token.signal(Token.java:195) at org.jbpm.graph.exe.Token.signal(Token.java:140) at org.jbpm.graph.exe.ProcessInstance.signal(ProcessInstance.java:271) at com.sample.TestDecisionNPE.main(TestDecisionNPE.java:53) Caused by: java.lang.NullPointerException at org.jbpm.jpdl.el.impl.JbpmExpressionEvaluator.translateExpressionToDollars(JbpmExpressionEvaluator.java:52) at org.jbpm.jpdl.el.impl.JbpmExpressionEvaluator.evaluate(JbpmExpressionEvaluator.java:38) at org.jbpm.jpdl.el.impl.JbpmExpressionEvaluator.evaluate(JbpmExpressionEvaluator.java:30) at org.jbpm.graph.node.Decision.execute(Decision.java:110) ... 8 more This bug can be tested using the following test case: package com.sample; import java.lang.reflect.Field; import java.util.ArrayList; import java.util.List; import org.jbpm.graph.def.ProcessDefinition; import org.jbpm.graph.def.Transition; import org.jbpm.graph.exe.ProcessInstance; import org.jbpm.graph.node.Decision; import org.jbpm.graph.node.DecisionCondition; public class TestDecisionNPE { public static final void main(String[] args) throws SecurityException, NoSuchFieldException, IllegalArgumentException, IllegalAccessException{ ProcessDefinition processDefinition = ProcessDefinition.parseXmlString( "<process-definition>" + " <start-state>" + " <transition to='d' />" + " </start-state>" + " <decision name='d'>" + " <transition name='one' to='a'>" + " <condition>#{a == 1}</condition>" + " </transition>" + " <transition name='two' to='b'>" + " <condition>#{a == 2}</condition>" + " </transition>" + " <transition name='three' to='c'>" + " <condition>#{a == 3}</condition>" + " </transition>" + " </decision>" + " <state name='a' />" + " <state name='b' />" + " <state name='c' />" + "</process-definition>"); // start-state.
