Resource scanning happens mpre than configured interval

by san_hegde

Hi, I have configured Resource Scanner to scan at the interval of 3600 seconds(1 hr). But it actually scans 3 times in the duration of one hour. My configuration is as below. <drools:resource-change-scanner id="s1" interval="3600" /> When I checked the log file it actually scans 4 times in a hour. Log is as below.

Re: [rules-users] Activation-group and salience

Error Creating New project

by Joe White

I received this error in the drools workbench when creating a new project: Unable to complete your request. The following exception occurred: java.lang.NoSuchMethodError:org.guvnor.common.services.project.events.NewProjectEvent.(Lorg/guvnor/common/services/project/model/Project;Lorg/uberfire/rpc/SessionInfo;)V. The project was not created but once I refreshed the browser it showed up. Should I assume my project is corrupt or is it valid? This is on 6.0.1 final (with the merged deployment changes). Thanks Joe

named query TasksAssignedAsPotentialOwner doesn't work with MySql db

by Frank Knoll

Hi, When I add a task (having two potential owners) by calling the method addTask followed by calling the method getTasksAssignedAsPotentialOwner of org.jbpm.task.service.TaskClient I expect to receive a list of TaskSummaries containing at least the previously added task. But I actually get an empty list! Here is my setup and possible solution: I am using the trunk version of ./jbpm-human-task/src/main/resources/META-INF/orm.xml and a MYSQL database. When calling addTask the Task table will be populated with a NULL actualOwner_id. The named query TasksAssignedAsPotentialOwner "select new org.jbpm.task.query.TaskSummary(...t.taskData.actualOwner...) from ... left join t.taskData.actualOwner ..." of orm.xml generates SQL consisting of an inner join "inner join OrganizationalEntity user7_ on task0_.actualOwner_id=user7_.id" which doesn't take the NULL actualOwner_id correctly into account. When I replace the named query TasksAssignedAsPotentialOwner with "select new org.jbpm.task.query.TaskSummary(...actualOwner...) from ...left join t.taskData.actualOwner as actualOwner ...", then the generated SQL consists of an "left outer join OrganizationalEntity user2_ on task0_.actualOwner_id=user2_.id" which takes the NULL actualOwner_id correctly into account. So I get a List of TaskSummaries containing the added task. Is this a correct fix?
