Line 108: $this->_output.=$this->processOpenWidget($type,$match[4][0],$match[2][1]);
It should be: $this->_output.=$this->processBeginWidget($type,$match[4][0],$match[2][1]);
It crashes when using Alternative Templating Syntax this way:
<com:WidgetClass property="value">
– content –
</com:WidgetClass>
I did the change and it works
