In Guvnor 5.4.0.final, when user1 initially logs in and updates a asset(

different asset by user2 still show as done by user1 which is incorrect.
updates done by user2 need to be sh
Jervis,
Thank You for confirming the issue.
The scenario I am having is as such.
the first time Guvnor 5.4.0.final in Tomcat 7 is started, I am able to
connect to both webdav folders and also through a java client using basic
authentication.
but when I disconnect the web folders connection
I am able to login into guvnor login page correctly using the same
id/password. however, when using windows webdav web folders or even the
eclipse drools plugin, it does not seem to work.
when I intentionally give the incorrect id/pwd, I do get an authentication
error as expected.

Thank You for forwarding that link. I have successfully used that in the

I can use field1 in (A,B,C)
but no option to specify

if no other option within the guided decision table, I suppose I would have

can you try modify instead of update in the first rule as

modify as I understand does update and insert.
without modify, the changes done in first rule are not visible to other

does this issue happen for any previous version of Guvnor data such as 5.0

does this mean, we cannot rely on 5.3.0 version of Guvnor code when
migrating data from a previous version and should rather apply the fix ?

we already have several scores of rules in place. the requirment is to
change the rule(s) in such a way as to keep it minimal and still achieve
the result expected.
having to write additional rules would be the last option.

I tried to use the function in a BRL editor in Guvnor.
In the consequence part how do I correctly call the function?

running tests scenarios in Guvnor 5.2.0.Cr1 seems to be causing memory leak

causing the leak within Guvnor as well ?
