> You can not call a s:link with propagation="none" linked to an action with @Begin from a page with conversation-required="true" to a page with conversation-required="true" because it will redirect you to the no-conversation-view-id. (And I think it shouldn't do that, it should allow you to reach the page you originally meant to reach, because the action has a  @Begin and it should consider that)
> Menu.java code:
> @Name("menu")
> public class Menu {
> 	@Begin
> 	public String goToCategoryList(){
> 		return "/CategoryList.xhtml";
> 	}
> }
> layout/menu.xhtml code:
> <s:link value="Category List By Action" propagation="none" action="#{menu.goToCategoryList}"/>
> And in CategoryList.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-2.0.xsd"
>       no-conversation-view-id="/Blank.xhtml" conversation-required="true">
>       
>    <param name="firstResult" value="#{categoryList.firstResult}"/>
>    <param name="order" value="#{categoryList.order}"/>
>    <param name="from"/>
>    <param name="name" value="#{categoryList.category.name}"/>
> </page>
> The funny thing is that this makes the menu option work intermittently:
> first time works (from a page without conversation-required to a page with conversation-required)
> second time does not work (from a page with conversation-required to a page with conversation-required) and it gets redirected to Blank.seam
> third time works (from a page without conversation-required to a page with conversation-required)
> And so on and so forth...
> The big question here is, if the @Begin is not really working, why it does work the first time? because if I comment the @Begin::
> Menu.java code:
> @Name("menu")
> public class Menu {
> 	//@Begin <----THIS IS NOW COMMENTED
> 	public String goToCategoryList(){
> 		return "/CategoryList.xhtml";
> 	}
> }
> Then It fails always. I think the propagation="none" linked to action with @Begin should work always or fail always, (just to be clear I think this should be fixed so that it works always)
