Communicating between widgets without modifying one of the widgets

JordanChapman

I have one widget that I cannot modify. It takes a GeoRSS file, adds points to the map with a marker and also places more info in an InfoWindow (the infoWindowRender is a PopUpRenderer) which appears when the user clicks the point.

I need to somehow communicate to another widget which I am developing, passing a single datum (a uid).

I'm not really sure if there is a way to do this without modifying the first widget, however I discovered that the infoWindow accepts html links, and that you can listen for links prefixed with "event:" via http://circlecube.com/2008/12/asfunction-texteventlink-tutorial-for-as3-flash-html-link-to-call-actionscript-function-tutorial/.

So now I'm wondering if there is any way to get a reference to the text in the infoWindow so that I can attach this listener, or if there is a better way to pass the id between the two widgets (because my way seems pretty odd).

Thanks

Thank you for your reply. I've already looked into communication between widgets using the method described in the links, however (as I stated in my original question) I cannot edit one of the widgets to include the adding of the necessary shared data. I understand that this may not be possible, and if it is it may be very "hacky", but I just wanted to make sure that it was indeed impossible or to see if there are any suggestions as to how I can overcome this obstacle.

Thanks
