Hello,
I am trying to cerate a new entry, entity bean, using three pages with the help of jBPM
similar to the example illustrated in jbossworld-seam-lab.zip file. These three pages are
going to be used in a RESTful application that follows the blog example.
So, I have a data entry page called newentry.jsf, similar to the bolg example, that has a
reference to a variable created with the help of the @Factory annotation. In that page the
variable is referenced just like any bean:
| <h:inputText id="title" value="#{newEntry.title}"
| size="70" maxlength="70" required="true"/>
|
The method that creates the variable is in a stateful session bean, to take advantage of
jBPM pageflow:
| @Stateful
| @Name("postAction")
| public class PostAction implements PostActionInterface{
|
| @In(create=true)
| private Category category;
|
| //@In(create=false, value="newEntry")
| @In(create=false)
| private Entry entry;
|
| @Factory("newEntry")
| public void createNewEntry(){
| entry = new Entry(category);
| }
|
| @Logger
| private Log log;
|
| //@Begin(pageflow="new-entry", join=true)
| @Begin(pageflow="new-entry")
| public void startPost(){
| log.info("Starting to create a new post");
| }
|
| @Remove @Destroy
| public void destroy(){}
| }
|
As you might have noticed, there is a page event in pages.xml that is supposed to call
startPost() method in order to start a new conversation:
| <page view-id="/newentry.jsf"
action="#{postAction.startPost}"/>
|
Unfortunately, when I try to access the newentry.jsf page I get the following stacktrace:
| SEVERE: Error Rendering View[/newentry.xhtml]
