Hi there,
Just wanted to know if there is a better way to listen for an event in an itemrenderer. I’m working on a mobile app, which uses sqlite database and cairngorm framework. I have a list in my view which has my CustomRenderer.as as it’s itemrenderer. This renderer initially loads basic data and displays it(data is binded which we get in model). Now, I also have a button on this renderer on clicking of which, I need to get some more details by querying the db (I avoided this query on initial load as it degraded the performance) and display this detailed data only on this renderer on which I click the button. Currently this is how I am achieving it: 1. On click on button in the renderer, I am dispatching a cairngorm event, which calls a command class, which is where I query db and receive detailed data. This data is stored in a model variable. 2. As soon as I store data in model variable, in next line I am dispatching this event within same command class : FlexGlobals.topLevelApplication.systemManager.dispatchEvent(*new*Event(ApplicationModelLocator.ON_DETAILED_DATA)); 3. I have added a listerner in the constructor of CustomRenderer.as: FlexGlobals.topLevelApplication.systemManager.addEventListener(ApplicationModelLocator.OVERVIEW_TREND_CLICK_DATA, onOverviewTrendClickData, *false*,0,*true*); 4. In onOverviewTrendClickData function I build the extra UI that is needed to show the detailed data. However, in this approach, the onOverviewTrendClickData function gets triggered many times(based on number of renderer items that are displayed in the list). Can you kindly let me know if there is a way I can avoid it? Or any other approach to achieve this? Warm regards, Deepak
