I am not sure if I am missing something, but if I create a new Data Service and then use it in a page/widget, and then later realize I missed something in the Data Service and go back and update it. The page/widget never sees the updated data service. The only thing I have found is to remove the data service from the page/widget, select ok, go back into the data service settings and re-add it, and then I have to redo all the bindings to my fields. I imagine there has to be a better way and I am just missing it. Hoping someone can point it out.
