I was guessing as much, but wasn't sure. Thanks for confirming. 


I have been implementing this functionality via Ajax and jQuery (I tried a bunch, including Gritter [1]), but have now settled on jBar [2], and am very happy with it (there are tons of Growl-type jQuery plugins). The process flow is very simple --


a. user does something (logs in, logs out, or saves or deletes a record by clicking on a button)
b. an Ajax query is fired that is trapped by a Dancer get/post, as appropriate
c. a return value is sent back that jQuery catches, and fires a jBar message


There is nothing unusual on Dancer side. There is this little snippet on the client side


C = {
save: function() {
$.ajax({
url : this.config.uri + "/save",
type : "POST",
data : query_str,
dataType: "json",
error : function() { alert("Error loading html document"); },
success : function(rc) {
(rc === "0") ? C.growl("Error", "Failed to save") : C.growl("Success", "Saved successfully");
}
});
},

growl: function(title, text) {
$.fn.bar({
color : '#1E90FF',
background_color : '#FFFFFF',
removebutton  : false,
message : text,
time  : 4000
});
}
};


Nothing against the plugin, but I just want to make sure I am not missing out on any goodie that I am not recognizing.
