properties get calculated wrong when tweening

[firsara]

just noticed this bug after upgrading from 1.16.1. Here's a simple example that illustrates the issue:

<button id="button">Button</button>
<script>
document.getElementById('button').style.opacity = 0;
TweenLite.to(document.getElementById('button').style, 2, {opacity: 1});
</script>

the tween renders fine but finishes at opactiy 10 instead of 1 (setting different easings like Quint.easeIn) makes it look even worse.

Did not look into the code in detail myself but would be nice if you have a hint so I can look at it myself.

Ah, very interesting - that has to do with the fact that the object you're tweening is returning a STRING as the from value rather than a number. I'll apply a workaround in the next update. Thanks for letting us know. In the mean time, you could just use CSSPlugin or tween a proxy object and use an onUpdate to apply the value.

Ah ok got it, thanks for pointing out the CSS Plugin! Was just strange for me as it used to work "correctly" in earlier versions...

This should be resolved in the latest update (1.18.1). Thanks again for pointing it out.
