Nested Conversation - Return to Parent
I know there are a lot of posts on nested conversations and I've looked through most of them. However, I have narrowed one problem down to a simple, easy to reproduce example of bizarre (IMO) behavior. Here goes...
Here is a simple Outer.xhtml page to start a conversation:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:s="http://jboss.com/products/seam/taglib">
<body>
<h3>Outer Page</h3>
<s:link id="startNested"
view="/test/Inner.xhtml"
value="Start"
propagation="nest"/><br/>
<h:outputText value="The conversation id: #{conversation.id}"/> <br/>
<h:outputText value="The conversation description: #{conversation.description}"/> <br/>
<h:outputText value="Is this conversation long running?: #{conversation.longRunning}"/> <br/>
<h:outputText value="Is this conversation nested? #{conversation.nested}"/><br/>
<h:outputText value="This should show ONLY if the conversation is nested"
rendered="#{conversation.nested}"/>
</body>
</html>
There is a Outer.page.xml page as well:
<?xml version="1.0" encoding="UTF-8"?> <page xmlns="http://jboss.com/products/seam/pages" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.1.xsd" login-required="false"> <begin-conversation join="true"/> <description>Outer Conversation</description> </page>
As you can see, the s:link in the Outer page starts a NESTED conversation. Here is that page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:s="http://jboss.com/products/seam/taglib">
<body>
<h3>Inner Page</h3>
<s:link id="endNested"
action="#{conversation.endAndRedirect}"
value="End"
propagation="end"
rendered="#{conversation.nested}"/> <br/>
<h:outputText value="The conversation id: #{conversation.id}"/><br/>
<h:outputText value="The conversation description: #{conversation.description}"/> <br/>
<h:outputText value="Is this conversation long running?: #{conversation.longRunning}"/> <br/>
<h:outputText value="Is this conversation nested? #{conversation.nested}"/><br/>
<h:outputText value="The parent conversation id is : #{conversation.parentId}"/><br/>
<h:outputText value="This should show ONLY if the conversation is nested"
rendered="#{conversation.nested}"/>
</body>
</html>
And the Inner.page.xml:
<?xml version="1.0" encoding="UTF-8"?> <page xmlns="http://jboss.com/products/seam/pages" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.1.xsd" login-required="false"> <begin-conversation join="true"/> <description>Inner Conversation</description> </page>
When you go to the Outer page you will see something like this:
Outer Page Start The conversation id: 35 The conversation description: Outer Conversation Is this conversation long running?: true Is this conversation nested? false
Then clicking on the Start link...
Inner Page End The conversation id: 36 The conversation description: Inner Conversation Is this conversation long running?: true Is this conversation nested? true The parent conversation id is : 35 This should show ONLY if the conversation is nested
Notice the parentId of 35. Now, the End link does a endAndRedirect which correctly takes you back to the Outer page:
Outer Page Start The conversation id: 36 The conversation description: Outer Conversation Is this conversation long running?: false Is this conversation nested? true This should show ONLY if the conversation is nested
Hmmm. You would expect the conversation id to be 35, not 36. I thought we ended that by clicking the s:link endAndRedirect on the Inner page. Why is it still showing the old cid? Also, notice that it thinks the conversation is nested. Why is this? This creates a problem because, as you can see, the last line was only supposed to render if the conversation was nested.
This is REALLY confusing to me. What am I doing wrong? I can't think of a simpler example than this.
