Calling an ActionScript3 Method From a Item Render in Flex
After receiving an email from Adobe detailing an application to load XML data into a DataGrid (written by Christoph Rooms) I hit a wall when trying to call a method in my actionscript. The DataGrid column had an mx:Image contained within mx:Component in an itemRenderer so that a little icon image can be displayed according to the xml data.
When I edited click=”…” and inserted my reference to an actionscript method I encountered:
1180: Call to a possibly undefined method myMethod
So I scoured the net, help files and saw ways of tackling this issue, some involving (if I understood them correctly) creating a custom event class then calling a function which is situated in an mx:Script tag which itself is within the mx:Image tag ?:)?
Anyway, the solution was in time found (thanks to my flex bible) and it is irritatingly simple. It turns out as always its a scope issue, the mx:Component tag defines a new scope where the local scope of the item renderer is defined by the MXML code.
So the outerDocument reference to call the function on the containing page saves the day!!! cool…
