Error CB 1.9 ../com_comprofiler/plugin.foundation.php on line 2580

Hy,

i've a strange problem with an implemented "iframe".

Versions: Joomla 2.5.9, CB 1.9

Problem:
If i open this iframe the following error occour:

Call to a member function get() on a non-object in /mnt/webspace/..../administrator/components/com_comprofiler/plugin.foundation.php on line 2580

The strange thing is, if i do this with a registrated user, everything works. If i log-out and do this as a public-people this error comes.
So i didn't know, if this is a problem of CB itself or Joomla and how to debug further to get the reasons for this.
If i debug the source-code of "plugin.foundation.php" on this line, this means that due to the checkJversion-function it goes to line 2580 and produce this error.
But why?

Any help is welcome... :woohoo:
Chris

Hy folks,

i found a workaround/solution for this, but i could not understand realy the background.
I disabled the joomla caching into the database, and it works as wanted.

Realy strange and mysterious behaviour.
:woohoo:
