[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1048) Documentation enhancement for injecting TaskInstance and ProcessInstance (add full package name)

Documentation enhancement for injecting TaskInstance and ProcessInstance (add full package name) ------------------------------------------------------------------------------------------------ Key: JBSEAM-1048 URL: http://jira.jboss.com/jira/browse/JBSEAM-1048 Project: JBoss Seam Issue Type: Feature Request Components: Documentation Affects Versions: 1.2.0.GA Environment: All Reporter: Arjan van Bentem Priority: Optional This may be too obvious for some, but maybe, just maybe, the following needs some enhancements: http://fisheye.jboss.com/browse/JBoss/jboss-seam/doc/reference/en/modules... reads: @StartTask [...] The jBPM TaskInstance will be available in a request context variable named taskInstance. The jPBM ProcessInstance will be available in a request context variable named processInstance. (Of course, these objects are available for injection via @In.) Built-in Seam components TaskInstance and ProcessInstance exist, but in fact are not used here. Due to the @Unwrap in org.jboss.seam.core.TaskInstance and ProcessInstance one actually gets an org.jbpm.taskmgmt.exe.TaskInstance and an org.jbpm.graph.exe.ProcessInstance injected. The exception when the Java code expects a Seam component is in fact clear: java.lang.IllegalArgumentException: Could not set field value by reflection: TodoList.processInstance on: org.jboss.seam.example.todo.TodoList with value: class org.jbpm.graph.exe.ProcessInstance However, this error might be embedded in a long list of other exceptions. For example, when adding the injection to the TodoList example it will be the 5th embedded exception in a message that starts with "javax.servlet.ServletException: Cannot get value for expression '#{todoList.description}'". Fix: Maybe the text above could be changed to include the full package name (hoping that it will not change in the near future): The jBPM org.jbpm.taskmgmt.exe.TaskInstance will be available in a request context variable named taskInstance. The jBPM org.jbpm.graph.exe.ProcessInstance will be available in a request context variable named processInstance. (Of course, these objects are available for injection via @In.) The very same text applies to @BeginTask. When not changing the documentation then, as of now, at least JIRA will show a hit when searching for "injection AND ProcessInstance" ;-) -- 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
