Apparently not. I tried using portNotification:


<http://kokkinizita.linuxaudio.org/linuxaudio/lv2/zita-at2#ui>
        a ui:X11UI ;
        lv2:requiredFeature urid:map;
        lv2:requiredFeature ui:idleInterface;
        lv2:extensionData ui:idleInterface;
        lv2:optionalFeature opts:options;
        ui:portNotification [
                ui:plugin 
<http://kokkinizita.linuxaudio.org/linuxaudio/lv2/zita-at2> ;
                lv2:symbol "eror" ;
                ui:protocol ui:floatProtocol ;
       ]
        .


based on the example found at 

 <http://lv2plug.in/ns/extensions/ui#portNotification>

which is the only one I found. But still no portevents for 'error'.


Ciao,
