Hello Dimitrios, I was trying to keep my post as generic as possible - which is why I didn't post specifics. In this particular instance however, I want to broadcast a Custom Event to a DataGrid residing on a Panel Control - to Scroll to the very top, whenever I add a new record to an ArrayCollection (residing in the ModelLocater). This can happen ONLY when I add a new record - and this is why I want to create a Custom Event for this. I am pushing for a Custom Event, because I don't think there is a built-in Event native to the DataGrid, that I can count on 100% of the time, to fire off ONLY when New Records are being added. The catch is, I can't dispatch the Event until I get my onResult response from the ColdFusion Server - indicating that the Database Insert was in fact successful, and that it's now okay to update the Model's ArrayCollection with the new ValueObject. Since the onResult logic resides in a Cairngorm Command Class, this is where I need to dispatch the Event from. Or at least initiate the command to dispatch the Event, which can reside in the ModelLocater - and dispatch it from there. Since all of my primary Views containing the Model-bound Controls, have a reference to the ModelLocater, I am thinking that there must be a way to dispatch these Events from the Model - and have a way for these Views to respond accordingly. If you could help me out in this regard, I really would be truly grateful. My application development, has literally come to a screeching HALT, because of me not knowing how to handle all these issues. I am tracking down every Event Broadcaster and Listener Tutorial I can get my hands on, so that I can learn more about how all this works. But in all of the examples I download and dissect, they ALL have a common View, that centralizes the code - in which it's quite easy to tie everything together. In my case, I have Views and Controls scattered all over the place - and they can be instantiated (or not be for that matter) at any given moment. I just don't know how to write code to broadcast Events in such a manner, so that each component has no prior knowledge of any other component. I hope I'm explaining all this properly... Thanks in advance, Mike

They say the Event model is so great, due to all the components being so loosely coupled. So either I am missing something really rudimentary here, or the Event model doesn't work the way I thought it did. In every example I've seen, for an Event Listener and Broadcaster setup to work properly, there must be a common link (like a container) between the 2 components - and then, there are the 3 key things which must be in place: The Event Listener, the Broadcaster, and the Function that gets run whenever the Event gets triggered. But what about the times, where I won't know for sure beforehand, which component I will be using at the time? Especially in a Cairngorm Application, where the Commands (which is where I desperately need to broadcast my Custom Events from) literally NEVER know where their Result Events are going to be sent. Of course, this is where the true power of Cairngorm-based Applications comes into play. All the Commands do really, is update the ModelLocater with their updated results - and because of Data Binding, the Components in the Application show the updated results. For me unfortunately, there is always much more that needs to be done, after a Result is brought back - and I need to find a way to tell my Application Components, to perform their next task (based on a Custom Event, that I broadcast). Can anybody show me how to Broadcast Events in such a manner, that they get disseminated "Application-wide"??? This way, I don't need to know beforehand, which Components will be Receiving the Events. This is the final thing on my plate that I must figure out, then I can FINALLY finish my app and find some peace in my life....
