I often hear developer asking about how to refresh different regions on the same page, when specific event happens in one of the regions - to refresh dependent regions. Usually developers would like to use something more simple than Contextual Event approach. There is more simple approach, may be it doesn't work for all the possible use cases - but it does it job, when just refresh is needed. This approach is based on dummy parameter value, being used as dependent region input parameter, with refresh option set to be ifNeeded.
For the sample test case, I'm using ADF 12c application (SimpleReloadRegionApp.zip). This application contains two AM's, to simulate two Data Controls to be used in separate regions:
Fragment from the first region, generates refresh event, when Save button is pressed. For this purpose, I have registered Property Listener to update flag variable. This variable value is initialised from refreshToken method, available in RefreshHelperBean: Read the complete article here.
