Hi Yves, The bug is due to the parser caching mechanism introduced in a previous version of the DITA OT. Oxygen 12 (which comes with DITA OT 1.5.2 bundled) has a patch to control the caching mechanism adding an ANT parameter called "disable.grammar.caching". You probably have this parameter set in Oxygen in the transformation scenario in the "Parameters" tab. Newer versions of the DITA Open Toolkit come by default with such an ANT parameter which can be toggled. Here's the long discussion: http://tech.groups.yahoo.com/group/dita-users/message/20167 Regards, Radu Radu Coravu <oXygen/> XML Editor, Schema Editor and XSLT Editor/Debugger http://www.oxygenxml.com On 10/13/2010 12:00 PM, Yves Barbion wrote:

Hi group

I know this topic has been discussed before, so I'm sorry to bother you with this again.

I've got non-breaking spaces in my topics ( ) and when I generate XHTML output with oXygen XML Author, my build fails and I get the message:

"The entity "nbsp" was referenced, but not declared."

I get a "build successful" with oXygen XML Editor though, so I must have fixed it there in some way, but I cannot remember how anymore. I also searched the archives, but to no avail.

Can someone please refresh my memory?

Thanks.
