resuming parent conversations

[knaas]

We have a screen where the user can enter an id into a field or search for the id by clicking a link. My approach to this was to have a s:link button that nests a conversation when the user clicks the search button. After fixing a small problem in the HtmlLink class (see [http://jira.jboss.com/jira/browse/JBSEAM-222]JBSEAM-222[/url]), I was able to get the nesting to occur correctly.

However, I need to be able to pop the user back to the parent conversation if they click a cancel button when they are on the search screen. This could be done in one of two ways:

1. Add a method to my search component that uses the same switch conversation technique as the Switcher component.
2. Use a simple s:link that would switch the user back to the parent conversation.

I would prefer using the s:link since it is so much simpler. How do I do this?

I would expect the following code to do this :

<s:link
 rendered="#{conversation.parentId!=null}"
 value="Cancel" action="#{conversation.pop}"
 styleClass="button" style="button"/>

However, Conversation.pop() only swapsthe workspace. Shouldn't it also do a redirect just like the Switcher component? Maybe I'm misunderstanding the use of the Conversation.pop() method.

Thanks.

yes, it just swaps the workspace. it does not do a redirect.

You could write a method like this:

public String popAndRedirect()
{
 Conversation.instance().pop();
 return Conversation.instance().redirect();
}

I guess I should add a method like that to Conversation :-)

I added redirectToParent() and redirectToRoot().
