The weird thing is all other conditional (on tab for example) still working.
There is something about the value tested by the REGEX but what ? How can I echo the tested value ?

Of course I have to <pre>var_dump</pre> but what object in wich file/class ?
I have already do it on the $this object of plugin/template/templatename/templatename.php but I don't have any anything relevant because the render of the html is already store in the object.

I hope CB 2.0 well be more MVC compliant

There is any specific $var you need to help me ?

I agree that the Joomla structure is specific MVC obvislousy I wanted to say : a nice overridable Joomla structure like for us making nice template easily

edit :
Echo $value => $field_value of the cbconditionalClass::getMatch( $field_value, $operator, $value );

/nophoto_n.png|tnnophoto_n.png/=>http://xxxxxxxxxxxxxxx/components/com_comprofiler/plugin/templates/oxalis/images/avatar/nophoto_n.png

$Match => 0

Still don't understand.
It seems doesn't working anymore in the dev server too...

I have use only this REGEX expression :#nophoto_n.png#
because the array treatment don't inspire me (but I'm not a real coder ^^ but i d'ont udernstand the implode('|*|) and now I have $match = 1 but still have the default image on screen...
