[JBoss Seam] - jBPM processInstance question
by xinhua
hi,
i want to inject processInstance in action after @CreateProcess like following code:
@Name("printSthAction")
| @AutoCreate
| public class PrintSthAction {
| @Logger Log log;
|
| @In
| private String content;
|
| @In
| ProcessInstance processInstance;
|
|
| public void printout(){
| log.info("=============> process Instance is null? #0", processInstance);
| log.info("=============> print #0", content);
| }
|
| }
jPDL:
<?xml version="1.0"?>
|
| <process-definition name="test">
|
| <start-state name="start">
| <transition name="printout" to="complete">
| <action expression="#{printSthAction.printout}"/>
| </transition>
| </start-state>
|
| <end-state name="complete" />
|
| </process-definition>
But, i got an exception like this:
| 10:31:53,653 ERROR [GraphElement] action threw exception: couldn't evaluate expression '#{printSthAction.printout}'

[JBoss Seam] - Editable tabular data the seam way?
by dajevtic
Hi everyone?
I have a question regarding a how to:
I want to have a dataTable (jsf ri or richfaces) where I have editable tabular data from a database table. I want (almost) every column to be editable (similar to excel). What is the best (technical) approach to achieve this?
Using framework configurations in components.xml is no good, because the EntityQuery is not held in any context, but is thrown away after the request ends. Also if I want to page fordward or backwards my changes will be discarded and the data will be read from the database again, ignoring my changes.
Currently I have an EJB3 stateful session bean that extends EntityQuery and I can instantiate it in components.xml with any Entity class!
However, I am not sure if there is a better (nicer) way to achieve this.
What is the real Seam-Way to get tabular editable data working?

@Name("searchsession")
public class SearchSession implements SearchLocal
{
@Out
private List details;
public String search()
{
details =em.createQuery("select s.storeName,s.reviewPoints,s.website from Stores s").getResultList();
System.out.println("list : "+details);
return "query";
}
}
and my facelet file contains,
<rich:dataTable width="483" id="details" rows="10" columnClasses="col" value="#{details}" var="val">
<h:column>
<h:outputText value="#{val.storeName}" />
</h:column>
<h:column>
<h:outputText value="#{val.reviewpoints}" />
