[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-2639) Task with taskform and timer leads to NPE

Task with taskform and timer leads to NPE ----------------------------------------- Key: JBPM-2639 URL: https://jira.jboss.org/jira/browse/JBPM-2639 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: jBPM 4.2 Reporter: Joram Barrez Assignee: Joram Barrez Fix For: jBPM 4.3 Code that throws NPE: private InputStream loadCSS(String executionId) { RepositoryService repoService = processEngine.getRepositoryService(); ExecutionService execService = processEngine.getExecutionService(); ProcessInstance instance = execService.createProcessInstanceQuery() .processInstanceId(executionId) .uniqueResult(); ProcessDefinition definition = repoService.createProcessDefinitionQuery() .processDefinitionId(instance.getProcessDefinitionId()).uniqueResult(); InputStream in = repoService.getResourceAsStream(definition.getDeploymentId(), PROCESSFORMS_CSS); return in; } When a timer is defined on a task, a new execution is created. The procInst query will return null in that case (PARENT != null in HQL).
