how to "return to a conversation"

[henrik.lindberg]

Is there a way to perform "return to whatever page was shown in a conversation when a nested conversation started" - i.e. I come to a nested conversation from several different pages in long running conversation, and I want to be able to let the user hit a "return to where you were" button.

Any suggestions on how to do that?

Hi henrik,

I have been doing this by passing a parameter when the nested conversation is started. The backing bean (SFSB in the nested conv. context ) grabs the parameter and keeps it in a String var for later use.

I am hard coding the outcomes,
If you find a better way, please lmk.

<s:button
 value="Details"
 propagation="nest"
 action="#{eventEditor.showEventDetails}" >
 <f:param name="seqNum" value="#{alarmRow.sequenceNumber}"/>
 <f:param name="ctx" value="servicealarmdetails"/>
</s:button>

@RequestParameter
private String ctx;

public String showEventDetails()
{
 jsfOutcome = ctx;

 if ( jsfOutcome == null)
 jsfOutcome = "someNonNullDefault";
 ...
 ...
}

@End(beforeRedirect=true)
public String done()
{
 return this.jsfOutcome;
}

I am using a combination of page parameters and ui:param to pass the viewid of the caller around.

I then use a s:link where the view is set with a #{param['backLinkId']} which works great, but I would prefer something less hardwired.

In fact, I pass two parameters around (as I support two levels of 'getting back').

I will probably end up implementing a general purpose breadcrumb bean.

Hi henrik,

Maybe the Conversation and/or ConversationStack classes could help with this?

This sounds very similar to the pattern we are using in seam-gen to do this (obviously, our preferred pattern). Get Seam CVS, create a project with seam-gen and take a look.
