[opencms-dev] Fwd: Publishing Error

[OpenCms]

Hi,

I tried to get an answer for my question in the mailing archives before
posting here, but I couldn't find a clue about what is happening.
So, this is my problem:
Sometimes when I publish a resource I get the system error:

com.opencms.core.CmsException: 0 Unknown exception. Detailed error:
Redirect 
fails :/system/workplace/action/explorer_files.html. 
root cause was java.lang.NullPointerException

When I click "OK", the error message is closed and the resource is normaly
published.

Any clues ?

Regards,
