possible bug version 1.7

CesiumJS
1

Hello,

While rendering CZML, when I click an Entity on the map (to display the info widget) I get this violent exception (below). My "description" HTML is this:
<div>Equipment: L<br/>Type: A321<br/>Depart: CLT<br/>Arrive: JFK</div>

An error occurred while rendering. Rendering has stopped.

    at P.render (http://localhost:8080/sdat/js/cesium_1.7/Cesium.js:462:1888)

I don't believe this happened in version 1.6 .

Also seeing this exception on entity click:

Hello,

we ran into this one also…(" Cannot read property ‘background-color’ of null ") is it caused by this bug: ?

https://github.com/AnalyticalGraphicsInc/cesium/issues/2545

if so you can fix it yourself in the code pretty easily which will suffice until the fixed version (presumably 1.8) is available

Also, we will most likely do a 1.7.1 release this Friday to address this (and a few KML bugs we found after release).

1.7.1 is now available and fixes this issue: http://cesiumjs.org/2015/03/02/Cesium-version-1.7.1-released/
