What is the correct way of refreshing all components connected to a datasource?

[fernandomm]

Hello,

I want to make a "refresh all" button which will loop on all datasources and refresh its data, hopefully forcing all components to also update data.

What i have tried is something like this:

myDataSource.fetchData(null, function(dsResponse) {
    myDataSource.updateCaches(dsResponse);
});

Is this the correct way of doing it?

Unfortunately it's not working. I don't get any errors but listgrids connected to this datasource don't update.

Thanks!
