Graphics layer item limit /rendering problem in api version > 4.12

Hi,

We are using graphics layers for many purposes.

When we checked v4.13, some layers appeared partially.

This happened only in big datasets.

My temp solution was to use featureLayer, and yet - it happened again in another part of our system.

I took the basic graphics example and managed to catch the point when the problem starts => more than 2205 graphic items.

I've created a simple codepen - https://codepen.io/nettaben/pen/QWwqbjy

Change `maxItemsV413` to 2204 to 'view' the markers ==> stops working when the number is greater.

If the api version is set to 4.12 - it is possible see more than 2205 points, while in v4.13 - it is not possible.

(change in the example).

UPDATE: not working with 4.14 as well.

Netta,

Move to 4.14 instead of 4.13.

Thanks, I've tried that already - not solving the issue.

Strange. Your codepen works for me when I change to 4.14

Send me a link to your new codepen maybe? did you change both css and js?

Maybe it's also dependent on the system's hardware?

anyway it's a bug....

Maybe try adding 5000 items

It worked in another computer with 2205 items in v4.14 but not with 2207 items

When I tried it, it broke at 3087

Seems to be hardware related. As you can see that Ken and I are able to get past the 2205 mark and you were able to on another machine.

Still a bug.

Thanks - It's not always easy to recreate such 'edgy' behaviors

Hi there,

I want to give you a quick update on the status of this issue. When the number of graphics is high (just short of 5K in this case), dojo promises are failing at 4.14. The team exploring options to move away from the current approach to improve overall performance when working with large numbers of graphics in a graphics layer.

As a workaround for this issue at 4.14, you can use the native promises shown below or please check out the test app here.

<script>
var dojoConfig = {
  async: true,
  isDebug: false,
  has: {
    "esri-native-promise": true
  }
};
</script>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thank you,

Hi there,

I want to let you know that this issue is fixed at 4.15. You can test the fix for the issue with the next version. Please let me know if you run into problems. Please use this test app to check the fix.

Thanks,
