problem about @Observer and Events

mnrz Feb 25, 2007 3:28 AM
Hello

I have a bunch of session beans with conversation scope. the conversation starts by clicking search button. when the result is shown on the second page the user can go to its setting page and after make his changes and apply them he/she turns back to the result page.

in order to apply new changes, I have a method namely extractColumn() on result action marked with @Observer("columnChanged") and in setting action when the action method calls to apply changes I put Events.instance.raiseEvent("columnChanged")

but the result is Exception:

I added the Events.instance.addListener("columnChanged","#{searchResult.extractColumn}");
but problem still exists.

1. Re: problem about @Observer and Events

gavin.king Feb 25, 2007 10:10 AM (in response to mnrz)

It looks like UserSettings.display() ends up calling back to UserSettings.columnHeaders(), via a third object, SearchResult.extractColumns(). I think this happens during bijection.

This is an error because SFSBs can't have re-entrant calls.

BTW, this will be much easier to debug if you use the leatest version of Seam.

2. Re: problem about @Observer and Events

mnrz Feb 26, 2007 12:47 AM (in response to mnrz)

yes, you're right. in extractColumn I am using an injected list from the same SB (UserSettings).

but how can I do that. I want when user changed its settings the respective SB understands and apply changes. is it possible to restart a SFSB?

I am using JBoss Seam 1.1.6
