[JBoss jBPM] - BPEl Problem: Assign with Literal values
by agusgr
Hello,
I'm working with the jbpm-bpel-1.1.Beta3 and with the BPEL plugin for eclipse.
I have develop several BPEL services but I have a problem with a portion of code.
When I try to deploy a proccess with this:
<bpws:assign name="Assign" validate="no">
| <bpws:copy>
| <bpws:from>
| <bpws:literal>
| <bpws:literal>'URL not found'</bpws:literal>
| </bpws:literal>
| </bpws:from>
| <bpws:to>$output.response/tns:Country</bpws:to>
| </bpws:copy>
| </bpws:assign>
|
I have this:

If I remove the literal statement, it works well.
The question is:
Does the jbpm-bpel-1.1.Beta3 extension supports the literal assignments?
Is there any error in my code?
Thank you and sorry about the long post
Agus

[JBoss Seam] - Conversation management in a desktop-like applikation
by jbuechel
I'm developing an application which has a similar look and feel as a desktop app. So there is a dropdown menu.
What i've done to open the different modules from the menu is just like this:
old menuItem.xhtml
<rich:menuItem value="#{messages.menu_manage_persons}"
| action="/modules/manageCatalogs/persons/main.xhtml" />
| .....
As i'm thinking of having a new long-running-conversation on each (more complex) module.
For ending the previous conversation for each menu item i ended up in writing a more complicated (more code) solution as following:
new menuItem.xhtml
<rich:menuItem value="#{messages.menu_manage_persons}"
| action="#{navigationManager.managePersons}" />
|
new NavigationManager class
@Scope(ScopeType.STATELESS)
| @Name("navigationManager")
| public class NavigationManager {
|
| public void queryOnlineDirectory() {
|
| }
| public void managePersons() {
|
| }
| ...
|
new entry in pages.xml
<page view-id="/*" login-required="true">
|
| <navigation from-action="#{navigationManager.queryOnlineDirectory}">
| <end-conversation />
| <redirect view-id="/modules/queryCatalog/catalog/main.xhtml" />
| </navigation>
| <navigation from-action="#{navigationManager.managePersons}">
| <end-conversation />
| <redirect view-id="/modules/manageCatalogs/persons/main.xhtml" />
| </navigation>
| ....
| </page>
|
I tried quite a lot ways to get around the NavigationManager class, but i couldn't figure out to achive this..
It would be greate if someone could give me a hint how to get around the use of the NavigationManager class (there are much more menu items of course and i don't like to implement this "needless" class)..
