[xwiki-users] null pointer in preferences - xwiki-users@xwiki.org

11 Mar 2008

Ricardo:

Thanks so much for picking this up.  And thanks for a
great wiki.

...
  1. desc xwiki.xwikircs
 2. select count(*) from xwiki.xwikircs where xwr_isdiff is null

I've been doggone busy for a couple of days and could
not follow this up right away.  Result: The machine I
was working on has been trashed (It was a  sacrificial
box used for experimental setups.)  Alas, I will try
again with the 1.3 release, which I see has been
posted in the meantime.  I hope your bug-fix campaign
is successfull even lacking this 2c. contribution. 
Truly sorry :(

Cheers,

Al

  Folks:

 I've been trying to install Xwiki on a Suse 10.2 linux
...
  distribution with apache-tomcat-6.0.16 and MySQL
 5.0.26 (the jdbc driver is
 mysql-connector-java-5.0.8.jar).  

 With either Xwiki 1.2.2 or 1.3.rc1 i get a null
 pointer exception when I get to the XWikiPreferences
 page i.e.

http://localhost:8080/xwiki/bin/objectadd/XWiki/XWikiPreferences?classname=…
...
  for 1.2.2.  Using 1.3 the error is terminal (no way
to
...
  recover).  Using 1.2.2 if I click on the
 XWikiPreferences header then I see a normal page,
 instead of the exception trace.  Except, if I try,
 say, to save a comment, I get another trace. 
I am not sure, but this sounds not far from a problem
Sergiu Dumitriu 
has been working out yesterday night in the IRC
channel. Please, just 
hoping he and others have e while to follow this
thread, could you 
provide us with some extra information?

It would be great if you could submit a couple of SQL
statements to
 your 
database and post here the answers. MySQL Console or
MySQL Query
 Browser 
could be used for this. Considering the database you
are connected to
 is 
xwiki:

1. desc xwiki.xwikircs

2. select count(*) from xwiki.xwikircs where
xwr_isdiff is null

I think this will help to know if we are facing the
same problem.
 Thanks!

Cheers,

Ricardo
