[JBoss JIRA] Created: (JBRULES-1457) please support containment test for map keys

by Godmar Back (JIRA)

please support containment test for map keys -------------------------------------------- Key: JBRULES-1457 URL: http://jira.jboss.com/jira/browse/JBRULES-1457 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: 4.0.4 Environment: any Reporter: Godmar Back Using MVEL as the language for clauses, there is no way to test whether a map's key contain a value. For instance: rule "number 1" when e : S(map.keySet() contains "x") then System.out.println("rule number 1"); end leads to a syntax error because Drool's parser does not allow function calls ("keySet())" in clauses. On the other hand, MVEL (according to Mike Brocks, please read http://jira.codehaus.org/browse/MVEL-53 ) does not provide an operator to test containment in a map's set (or values). He said he's considering adding a shortcut such as .keys and .values in 2.0 and recommended I open a Drools JIRA issue. Please provide a way to test for membership in a map's key and value set. -- 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: (JBRULES-2404) "not contains" operator doesn't work on inner fields

by Taras Svirskyi (JIRA)

"not contains" operator doesn't work on inner fields ----------------------------------------------------- Key: JBRULES-2404 URL: https://jira.jboss.org/jira/browse/JBRULES-2404 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler Reporter: Taras Svirskyi Assignee: Mark Proctor Consider following example. There are nodes that are connected into directed graph. Each node has special collection of attributes. Under some conditions attributes should be propagated along the edges in the graph. Lets model this with following code. /******* propagation rules **********************/ package com.test.collection; rule "move child" when c : Child() s : CNode( children contains c) l : Link( src == s, t : target && target.children not contains c ) then System.out.println("adding "+c+" from "+s+" to "+t); t.addChild(c); update(t); end /** Child.java (represent special attributes of a node) *******/ package com.test.collection; public class Child { private String name; public Child(String name){ this.name = name; } public String getName() { return name; } @Override public String toString() { return "child("+name+")"; } } /********* CNode.java - nodes of a graph *************/ package com.test.collection; import java.util.HashSet; import java.util.Set; public class CNode { private Set<Child> children; public CNode() { this.children = new HashSet<Child>(); } public Set<Child> getChildren() { return children; } public void addChild(Child ch){ children.add(ch); } @Override public String toString() { return "Node{children="+children+"}"; } } /**** Link.java - edges of a graph *******/ package com.test.collection; public class Link { private CNode src; private CNode target; public Link(CNode src, CNode target) { this.src = src; this.target = target; } public CNode getSrc() { return src; } public CNode getTarget() { return target; } } /********************* populate session with facts **********/ Child c0 = new Child("x"); Child c1 = new Child("y"); Child c2 = new Child("z"); CNode src = new CNode(); src.addChild(c0); src.addChild(c1); CNode target = new CNode(); target.addChild(c0); Link link = new Link(src,target); // populate with facts ksession.insert(c0); ksession.insert(c1); ksession.insert(c2); ksession.insert(link); ksession.insert(src); ksession.insert(target); /****************************************************************/ So with all that code listed above I've got following output from rules: -- adding child(x) from Node{children=[child(x), child(y)]} to Node{children=[child(x)]} -- That means that 'not contains' operator actually works as 'contains' one. Still when I changed it to older operator 'excludes' everything goes right printing out. --- adding child(y) from Node{children=[child(y), child(x)]} to Node{children=[child(x)]} --- I've noticed that rewriting rule in form of simple statements also fix issue. rule "move child" when c : Child() s : CNode( children contains c) t : CNode( children not contains c ) l : Link( src == s, target == t) then System.out.println("adding "+c+" from "+s+" to "+t); t.addChild(c); update(t); end -- 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: (EJBTHREE-1870) stopDelivery on active MDB results in exception (Session not found)

by Philip Dodds (JIRA)

stopDelivery on active MDB results in exception (Session not found) ------------------------------------------------------------------- Key: EJBTHREE-1870 URL: https://jira.jboss.org/jira/browse/EJBTHREE-1870 Project: EJB 3.0 Issue Type: Bug Components: ejb3 Affects Versions: 1.1.3 Environment: Mac OS/X Leopard, JDK 6, JBoss 5.1.0GA Reporter: Philip Dodds Attachments: stopdelivery-mdb.zip If you start an MDB and introduce a messages to it then use the stopDelivery method of the MDB's MBean to stop it consuming messages you get an exception. Note this problem only occurs if the MDB has a transaction in flight when the stopDelivery is called. 2009-05-20 12:30:52,499 ERROR [org.jboss.messaging.util.ExceptionUtil] (WorkManager(2)-44) Connectio nEndpoint[fe-oz919yuf-1-mj809yuf-bruz48-x21o4c5] sendTransaction [ur4-b6b39yuf-1-mj809yuf-bruz48-x21 o4c5] javax.jms.IllegalStateException: Cannot find session with id ie-qz919yuf-1-mj809yuf-bruz48-x21o4c5 at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.processTransaction(ServerConnectionEndpoi nt.java:835) at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.sendTransaction(ServerConnectionEndpoint. java:497) at org.jboss.jms.server.endpoint.advised.ConnectionAdvised.org$jboss$jms$server$endpoint$advised$Co nnectionAdvised$sendTransaction$aop(ConnectionAdvised.java:101) at org.jboss.jms.server.endpoint.advised.ConnectionAdvised$sendTransaction_N3268650789275322226.inv okeTarget(ConnectionAdvised$sendTransaction_N3268650789275322226.java) I have attached a slightly doctors version of the EJB3 MDB example code, it has been changed to introduce a sleep of 5 seconds in the MDB (to keep the transaction active longer) and also introduces a higher volume of messages to give you a chance to get to the JMX console and call stopDelivery. If you don't get an exception on the first attempt it is worth trying again as the transaction must be in flight for the problem to occur. -- 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

clarifiction wanted for Rules docs ---------------------------------- Key: JBRULES-1909 URL: https://jira.jboss.org/jira/browse/JBRULES-1909 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-docs-expert Reporter: Darrin Mison Assignee: Mark Proctor QE feedback from the SOA edition of the JBoss Rules Reference contained the following clarification request: "Agenda groups are a handy way to create a "flow" between grouped rules." The previous paragraph indicated that a flow between rules cannot be relied on. Are we saying that the flow between groups is a way around that limitation? Or is the term 'flow' being used in a different context here.

[JBoss JIRA] Created: (JBRULES-2609) Bad condition operator "===" (triple equals) in room fire example

by Julien Kronegg (JIRA)

Bad condition operator "===" (triple equals) in room fire example ----------------------------------------------------------------- Key: JBRULES-2609 URL: https://jira.jboss.org/browse/JBRULES-2609 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-docs-expert Affects Versions: 5.1.0.FINAL Environment: environment not relevant Reporter: Julien Kronegg Assignee: Mark Proctor Priority: Trivial Context: The "Quick Start" chapter/"The Basics" section uses an example of fire in rooms. Issue: In one of the rule example snippet, the condition operator used is "===" (triple equals) instead of "==" (double equals): rule "Status output when things are ok" when not Alarm() not Sprinkler( on === true ) then System.out.println( "Everything is ok" ); end Location: In version 5.1.0.FINAL and also in trunk/rev34481 in the following file: http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-docs/dro... : line 389 Priority: Since this is in the basics, beginners read that chapter, so the priority could be higher than "trivial" -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
