Entity's show property is not working as expected.

CesiumJS
1

Hey,

I'm running into an issue while setting entities with a polygon show property.

I set this property value based on the camera height, and it all works fine, until I add a new entity (not related in any way/value to the original one).

Once the new entity is added, the old entity's polygon suddenly appears even with its show set to false. While testing this issue I saw that when setting the polygon with extrudedHeight doesn't lead to this problem, however it also happens with polyline, and polyline doesn't have extrudedHeight property.

Check this fiddle http://jsfiddle.net/4stotb8a/.

Is there anyway to resolve it without using extrudedHeight?

Thanks for the report and sample code, this does indeed look like a bug. I submitted https://github.com/AnalyticalGraphicsInc/cesium/issues/2686 for it and I’ll send out another update once it’s fixed (which will hopefully be ASAP but definitely before 1.10).

Thanks for the reply.

Antoher issue, that I don’t know if related, but should be addressed I believe - the parent-child relationship is only valid for 1 level.
This means, that if I have a grandparent, it doesn’t affect the grandchildren.

I attach a sandcastle sample code.

When you click to hide the grandparents, it doesn’t hide anything.

When you click to hide the parents, it hides the children.

Is this intentional or a bug?

Thanks, I’ll try and look at this ASAP and get both issues fixed before 1.10.
