Recently I included the tagcloud snippet in one of my panels. In some pages it works fine,
but in other pages I get this error message in stead of the cloud:
Error number 4001 in 4: Error while parsing velocity page Main.Tags Wrapped Exception:

Sorry for the long text.
When I want to view All Tags from my menu, I get no tags, and the source of the page shows
a similar error message.
Any help is welcome.

Hi Inge,
I have no idea what this tagcloud snippet works (it's contributed
code). All I can tell is that the error seems because the snippet is
passing a NULL list to the XWiki sort() method. Actually the
implementation of the sort method cannot be simpler:
public List sort(List list)
{
Collections.sort(list);
return list;
}
So you should check the tagcloud code and modify it so that it
doesn't call sort when the list is NULL (and update the script in the
code zone when you've fixed it! :)).
Thanks
-Vincent

Sorry for the long text.
When I want to view All Tags from my menu, I get no tags, and the
source of the page shows a similar error message.
Any help is welcome.

Hi,
I have the same trouble.
I find out that Documents saved with Admin works fine, Documents saved with
"classic user" makes this problem ...
How should i do ?
Thanks !
Regards,
Benoit

Hi Inge,
I have no idea what this tagcloud snippet works (it's contributed
code). All I can tell is that the error seems because the snippet is
passing a NULL list to the XWiki sort() method. Actually the
implementation of the sort method cannot be simpler:
public List sort(List list)
{
Collections.sort(list);
return list;
}
So you should check the tagcloud code and modify it so that it
doesn't call sort when the list is NULL (and update the script in the
code zone when you've fixed it! :)).
Thanks

Recently I included the tagcloud snippet in one
of my panels. In
some pages it works fine, but in other pages I get this error
message in stead of the cloud:

Sorry for the long text.
When I want to view All Tags from my menu, I get no tags, and the
source of the page shows a similar error message.
Any help is welcome.

Hi,
I have the same trouble.
I find out that Documents saved with Admin works fine, Documents
saved with
"classic user" makes this problem ...
How should i do ?
It must be using some privileged api which require programming rights.
So just save it with a user having programming rights and it should be
fine.

Hi Inge,
I have no idea what this tagcloud snippet works (it's contributed
code). All I can tell is that the error seems because the snippet is
passing a NULL list to the XWiki sort() method. Actually the
implementation of the sort method cannot be simpler:
public List sort(List list)
{
Collections.sort(list);
return list;
}
So you should check the tagcloud code and modify it so that it
doesn't call sort when the list is NULL (and update the script in the
code zone when you've fixed it! :)).
Thanks
-Vincent

Sorry for the long text.
When I want to view All Tags from my menu, I get no tags, and the
source of the page shows a similar error message.
Any help is welcome.

I have try it : put the classic user in a group authorized in programming
rights, also admin rights ... nothing better.
Only the Admin user shows the tag cloud panel fine.

Hi,
I have the same trouble.
I find out that Documents saved with Admin works fine, Documents
saved with
"classic user" makes this problem ...
How should i do ?
It must be using some privileged api which require programming rights.
So just save it with a user having programming rights and it should be
fine.

Hi Inge,
I have no idea what this tagcloud snippet works (it's contributed
code). All I can tell is that the error seems because the snippet is
passing a NULL list to the XWiki sort() method. Actually the
implementation of the sort method cannot be simpler:
public List sort(List list)
{
Collections.sort(list);
return list;
}
So you should check the tagcloud code and modify it so that it
doesn't call sort when the list is NULL (and update the script in the
code zone when you've fixed it! :)).
Thanks
-Vincent

http://lists.xwiki.org/mailman/listinfo/users Recently I included the tagcloud snippet in one
of my panels. In
some pages it works fine, but in other pages I get this error
message in stead of the cloud:
