[jboss-user] [jBPM] - ClassCastException: JpdlProcessDefinition cannot be cast to ProcessDefinitionImpl

jordi elies [http://community.jboss.org/people/jelies] created the discussion "ClassCastException: JpdlProcessDefinition cannot be cast to ProcessDefinitionImpl" To view the discussion, visit: http://community.jboss.org/message/538997#538997 -------------------------------------------------------------- Hello everybody, I have a curious problem when I try to get all ProcessDefinitions of the RepositoryService. I execute this few lines: {code} ... RepositoryService repositoryService = processEngine.getRepositoryService(); ProcessDefinitionQuery pdq = repositoryService.createProcessDefinitionQuery(); List<ProcessDefinition> p = pdq.list(); ... {code} The first time I start jboss server all works fine, all process definitions are obtained without problem. The problem comes when I redeploy the webapp. Once redeployed, I try to get all the process definitions and a class cast exception is thrown on {code} List<ProcessDefinition> p = pdq.list(); {code} The stacktrace: {code} 13:41:12,260 INFO  [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.query.ProcessDefinitionQueryImpl@14d9f8e java.lang.ClassCastException:

org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:619) {code} Inside jBpm code, the bold line is where ClassCastException is thrown: {code} public class ProcessDefinitionQueryImpl extends AbstractQuery implements ProcessDefinitionQuery { ...   public Object execute(Session session) {     List<Map<String, Object>> propertyMaps = (List<Map<String, Object>>) super.execute(session);     List<ProcessDefinition> processDefinitions = new ArrayList<ProcessDefinition>();     for (Map<String, Object> properties: propertyMaps) {       String deploymentId = properties.get("deploymentDbid").toString();       String objectName = (String)properties.get("objectName");       RepositorySession repositorySession =

processDefinitions.add(processDefinition);     }     return processDefinitions;   } ... } {code} I'm doing something wrong? When I look for the process deployments with a DeploymentQuery there isn't any problem. Thanks in advance, any help would be appreciated. PS: I'm working with jbpm 4.3, spring, jboss.5.1.0.GA and I've the jBpm engine running embedded in the same web application. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/538997#538997] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
