I have having some difficulties invoking a PageFlow by clicking on a link in a
data table.
We are using Seam 1.1.5GA running on JBoss 4.0.5.
The high level use case is that the user is presented with a data table that
contains a number of subjects that need processing. The user can then click on
a link for each subject to start a registration process.
The registration process is complex and we feel best implemented with a page
flow.
We have a JSF page and a simple SLSB which properly displays the initial list
of subjects.
On the data table, we have the following command link:
| <h:commandLink action="#{registrationWizard.startWizard(subject)}"
| value="Register >>" />
|
|
We also tried a <s:link> as well.
The command link invokes a separate SFSB which manages the Registration Wizard
Conversation.
The startWizard method looks like:
| @Begin(pageflow="registration",join=true)
| public void startWizard(Subject s) {
| log.info("RegistrationWizard.startWizard[#0]", s.getId());
| this.currentSubject = s;
| }
|
The registration pageflow has the following start-page
| <start-page name="start" view-id="/regwiz_info.xhtml">
| <redirect/>
| <transition name="next" to="regwiz002" />
| <transition name="cancel" to="cancel" />
| </start-page>
|
I also updated pages.xml with the following:
| <page view-id="/regwiz_info.xhtml">
| <begin-conversation join="true" pageflow="registration"/>
| </page>
|
I will get the following message, even if I remove the above code from the
pages.xml file.
When I run the app, I am getting the following error message:
| java.lang.IllegalStateException: pageflow is not currently at a <page> or
<start-page> node (note that pageflows that begin during the RENDER_RESPONSE
phase should use <start-page> instead of <start-state>)
|
Can someone help me understand what I am doing incorrectly?
