I have two custom built symbols in PI Vision that both make pi web api post requests to update some data in the same AF template. Even though the post request updates the data value almost immediately, it still takes the dataUpdate(data) method several 5 second iterations to notice the change in AF. Is there a way for the data object passed to the dataUpdate() method to be updated with the correct values faster? Also what service calls the dataUpdate method for a custom symbol? I've tried using dataPump.requestUpdate() but that doesn't update the data object.
