dataList updated by a:commandLink
miojo Sep 28, 2010 3:18 PMIn the following scenario, when a user clicks in a link of the first dataList, the page is supposed to update the second dataList and the first description div. And when the user clicks in a link of the second dataList, the page is supposed to update the second description div.
It is a simple scenario, but it seems something is not working properly.
Although the second lists loads correctly and the first div presents the description of clicked item in the first list, this is printed in console:
16:19:16,506 WARN [org.jboss.seam.Component] Cannot create Seam component, scope is not active: areaInteresseHome(CONVERSATION)
Also, if the user clicks on any item of the second list, nothing happens.
Any help?
