See screenshot attached

Comment 3 Pedro Zapata 2013-11-05 04:12:21 EST

Thats a known issue (https://issues.jboss.org/browse/JBPM-4034).

The problems it seems to be caused by the following Weld issue https://issues.jboss.org/browse/WELD-1020.
It seems to be fixed in Weld 2.0. But unfortunately, Dashbuilder is based on Weld 1.1 as it's the version used by EAP

The issue will be fixed when adapting Dashbuilder to forthcoming versions of the AS. WildFly 8 may be.

Comment 4 Pedro Zapata 2013-11-05 04:12:58 EST

One possible workaround is using basic authentication instead of form based authentication.

Comment 5 Roger Martínez 2013-11-05 14:38:11 EST

Ok, 

so... this issue can be marked as duplicate and closed?

Comment 7 Pedro Zapata 2013-11-08 04:02:47 EST

It's not duplicated, as it's reported in a JIRA. We'll leave it open by the moment to keep track with low priority.
