API 4.7 LayerList strange behaviour

DavideLimosani — Tue, 19 Jun 2018 14:32:15 GMT

Hello everyone,

I have a big project with API 4.6 that is based on updates of LayerList Widget. I have found a big difference in the behaviour from 4.6 to 4.7.

Look at this sample:

JS Bin - Collaborative JavaScript Debugging

After 5 seconds all layers in map are removed. With API 4.6 the LayerList widget is completely cleaned, with 4.7 no, some layers / group layers are still there.

I know that 4.8 aren't officially released yet, but with 4.8 the behaviour is even different from 4.6 and 4.7......

Is this a bug? Is there some way to completely refresh LayerList widget after removing all layers from the map?

Thank you,

Davide

Hey David,

This does look like a bug. We'll look into it and report back what we find. Should be able to get this fixed for 4.8.

Thanks for reporting!

Hello Matt,

thanks for you answer. Please let me know because i need to know as soon as possibile if i can switch my application to 4.7 /4.8 or otherwise if i am stuck at 4.6. I strongly need to combine LayerList and Legend widget and the funcionality is not present in 4.6...

Regards,

Davide

Hey Davide,

We're working to get this fixed for 4.8 which will be the next release. If you would like to use 4.7, here is a workaround for the issue:

Hi Matt,

We submitted multiple cases related to Layer List Widget ( up to 4.7) ... my issue originally was related to the fact that the checkbox for sub layers do not honor visibility of layers ( as the scale changes). The labeling however used to honor the visibility ( it still looks the vase in 4.8) . Those issues look a luxury now

I could at least see the check boxes to hide or show the sub layer.

Now it looks worse .. there is no checkbox for the sub layers ...

Thanks,

Hi Abebe,

check the VisibilityMode of your sublayers. It should be "independent" and not "inherited".

That suggestion does not apply to a case where you have a single map service that contains group layers and layer groups will be visible at predefined scales ... because you add it as a single MapImageLayer , because that property is for GroupLayers
