I have created a datafeed which returns "Today's date" (from Individual values -> Information) in precision of minutes. The text field which displays the result is refreshed every 30 seconds. Unfortunately the date is never refreshed. It always stays on the original value retrieved at the start. How can I get a refreshed current date/time?
This is just a simple sample. I need a refreshed date for a sliding time window which moves forward as the time goes by.
Running with MashZone 2.1.
If you have a construct in your feed where there's only the "Information" operator that is connected to the output via a "value to data feed" operator, then the date won't get refreshed, because the cache lifetime of the feed is too long.
Currently, there's only a workaround to solve your problem: Add a dummy source operator (e.g. a CSV operator) to your feed and connect it in some way to the output. In the CSV operator, you can configure the cache lifetime to e.g. 15 seconds.
If you use that feed, your date will get refreshed in the MashApp.
Thanks, this works :)
Indeed I do not need the dummy CSV because my real datafeed already reads an Excel. But because the Excel content does normally not change, I had specified a cache time of 24 h. Now I have reduced this chache time to 30 sec. And because the stuff I read in from the Excel is not too much, I can life with the overhead.
