potential small bug

CesiumJS

Hello

Here a potential small bug in the last Cesium release when using event CZML file at EventSource format

switching a Billboard “show” from false to true, the billboard is not becoming visible
Working well from true to false.

So no way to make it visible again

here a sample if ever it could be an issue in the syntax itself

event: czml
data: {“id”:“F-XXXX”,“label”:{“text”:“F-XXXX”,“scale”:0.5,“show”:false,“horizontalOrigin”:“LEFT”,“verticalOrigin”:“CENTER”,“pixelOffset”:{“cartesian2”:[12.0,0.0]}},“billboard”:{“image”:“http://maps.google.com/mapfiles/kml/paddle/ylw-blank.png",“scale”:0.5,“show”:false,“horizontalOrigin”:“CENTER”,“verticalOrigin”:"BOTTOM”}}

event: czml
data: {“id”:“F-XXXX”,“label”:{“text”:“F-XXXX”,“scale”:0.5,“show”:true,“horizontalOrigin”:“LEFT”,“verticalOrigin”:“CENTER”,“pixelOffset”:{“cartesian2”:[12.0,0.0]}},“billboard”:{“image”:“http://maps.google.com/mapfiles/kml/paddle/ylw-blank.png",“scale”:0.5,“show”:true,“horizontalOrigin”:“CENTER”,“verticalOrigin”:"BOTTOM”}}

thanks

Here with the position information and not working as well

data: {“id”:“F-XXXX”,“position”:{“cartographicDegrees”:[1.0,50.0,0.0]},“label”:{“text”:“F-XXXX”,“scale”:0.5,“show”:false,“horizontalOrigin”:“LEFT”,“verticalOrigin”:“CENTER”,“pixelOffset”:{“cartesian2”:[12.0,0.0]}},“billboard”:{“image”:“http://maps.google.com/mapfiles/kml/paddle/ylw-blank.png",“scale”:0.5,“show”:false,“horizontalOrigin”:“CENTER”,“verticalOrigin”:"BOTTOM”}}

data: {“id”:“F-XXXX”,“position”:{“cartographicDegrees”:[1.0,50.0,0.0]},“label”:{“text”:“F-XXXX”,“scale”:0.5,“show”:true,“horizontalOrigin”:“LEFT”,“verticalOrigin”:“CENTER”,“pixelOffset”:{“cartesian2”:[12.0,0.0]}},“billboard”:{“image”:“http://maps.google.com/mapfiles/kml/paddle/ylw-blank.png",“scale”:0.5,“show”:true,“horizontalOrigin”:“CENTER”,“verticalOrigin”:"BOTTOM”}}

I believe you are encountering this issue: https://github.com/AnalyticalGraphicsInc/cesium/issues/4408 which should be fixed soon.

This issue was just fixed and will be available in the Cesium 1.27 release available on November 1st.

Best,

Hannah

Thank you so much Hannah. FYI, once an existing entity has some issue with the show properties for Billboard, I think they are a side effect on the Label propertie. No more able to switch its “show” propertie
Perhaps interresting to look at this as well

Thanks Bruno. I think that has been fixed as well, but would you be able to put together a code example so I can verify that?

Thanks,

Hannah
