Hi -I have created a custom cell that displays a "duration" of time between a start date and end date (public class DurationCell extends AbstractCell<Date[]>). If the end date is null, I would like the duration to "count up," like a stopwatch.I'm stuck with how to periodically (every second) update the value of that cell. I would prefer to not have to alter the underlying data object every second, but I don't know of another approach.Thoughts?
I think you could add a specific CSS class to an element within the cell, and add the start date in an attribute (e.g. data-start-date="1414889795967"), then in a timer get all elements with the class (using getElementsByClassName or querySelectorAll; for now you'll have to use JSNI, or Elemental, or GQuery) and process their data-start-date="" attribute to compute the duration and set their content.
