First SVG morph I have done so far and I am trying to do the infamous morph from open menu bars icon to the close menu icon. 


Open Menu Icon consists of three paths.


1) #open_top_bar  --> morphs into #close_top_bar


2)  #open_middle_bar  --> autoAlpha to 0


3)  #open_bottom_bar  --> morphs into #close_bottom_bar


Getting some errors in my console I don't understand that results in no morphing.


Uncaught TypeError: Cannot read property 'toUpperCase' of undefined


Doesn't give me a line number but I assume one or more of my selectors is returning null?

If you switch this:

tl = new TimelineMax();
tl.to($("#open_top_bar"), 1, {morphSVG:$("#close_top_bar")}, "+=1")
tl.to($("#open_middle_bar"), 1, {autoAlpha: 0}, "+=1")
tl.to($("#open_bottom_bar"), 1, {morphSVG:$("#close_bottom_bar")}, "+=1")

to this:

tl = new TimelineMax();
tl.to("#open_top_bar", 1, {morphSVG:"#close_top_bar"},0)
tl.to("#open_middle_bar", 1, {autoAlpha: 0}, 0)
tl.to("#open_bottom_bar", 1, {morphSVG:"#close_bottom_bar"}, 0);

everything is working just fine. :)

Yep, it had to do with the jQuery wrapper(s). We'll add some code to the next version to work around that.
