'Error during remote request' since 1.52 Seam revision

[superfis]

Hello,

Until latest (1.52) Seam revision appeard, my project using Seam Remoting was working correctly.

Now there is an error:
2006-04-11 10:35:51,718 DEBUG [org.jboss.seam.core.Manager] Storing conversation state: 3

How to solve this problem?

Hi,

Having the same issue. In the storeConversation method of the Manager class the pageContext returned from Contexts is null. This happens during a remote request.

I added a check for the page context. Looks like this:

if (Contexts.isPageContextActive()) {
 ........
}

This seems to have fixed the issue for me. Everything else is still functioning OK.

It seems as if it solved my problem also. Thanks a lot.

Just fixed in CVS. Sorry, I missed one ;-)

(You should have reported this in JIRA, btw.)

Hi,

A similar issue is occurring due to a call to Contexts.getPageContext at line 311 of the manager class. Employing a similar solution as above seems to work.

JIRA - JBSEAM-213
