refreshInterval in MapImageLayer not working as expected

HanochS

Hi,

I have configured refreshInterval for MapImageLayer to be 0.1 (6 seconds). After monitoring the requests I can see that the timing is not as configured and seems awkward.

I attached a screenshot with the timing. You can see that requests are triggering each 12/6 sec randomly.

From the documentation I understood it should trigger each 6 sec but that is not the case.

Regards,

Hanoch

Yes indeed. We did make improvements to refreshable layers at version 4.21 and 4.22. In the process we fixed bugs as well.

I am using 4.17, were there any changes related to refreshintervel between those versions?

Hi there,

What version of the JS API are you using? At 4.22, I can see that refresh is triggered at every 6 seconds exactly. The response time can vary from the server.

Here is a simple test app that listens to the refresh event on the layer and it is goes off every 6 seconds: https://codepen.io/U_B_U/pen/ZEaVQmW?editors=1000
