Bug seems in
function addCss($mixedFiles, $bDynamic = false) { ... } in file BxDolTemplate.php .
If the second param $bDynamic ==true, it works. But if $bDynamic ==false, the .css file won't be included (linked) to resulted page code.
For example, modules/boonex/messanger/classes/BxMsgModule.php, line 142
$sResult .= $this->_oTemplate->addCss("invitation.css", true); is ok.
But in inc/classes/BxDolTwigModule.php, line 409
$this->_oTemplate->addCss ('main.css');
dosn't work. You can't find the main.css link in the output source ocde of browser page.
Does anyone disagree with this ?
