[xwiki-users] RES: Failed to retrieve workspace

5 Aug 2013

      Eduardo firstly, thank you for your attention,

Then... I had a XE installation with the schema name "WIKDCTI".
After to discover the necessity of create more wikis I have decided to install XEM. After the installation I created a Wiki descriptor in order to point my first wiki.
Then the following error started:

Hi Danillo,

We need more information about the error you are getting. Could you provide the full stacktrace? (not just the exception message)

Also, please provide more details on the steps you took when getting this exception. ("I have pointed my first IT wiki to my XEM") Is it reproducible with a fresh install of XEM or is it related to your specific setup?

Thanks,
Eduard

Hello People,
How Are you?
In the last weeks my wiki project became from a just wiki to a set of
wikis after some manager of other departments take knowledge of this tool!
Haha Everyone need knowledge management in my company!
Well, then I have decided to install the XEM to support and facilitate
the administration of the wikis, but when I have pointed my first IT
wiki to my XEM the error below started to begin.
Failed to retrieve workspace with ID [[wikdcti,
NullPointerException]]: {1}
java.lang.NullPointerException: null
I tried to put various alias but nothing works.
Anyone know where I can set a workspace with ID?
Thank you
Danilo
