Oh, my apologies. This is a different story altogether. It seems that Composer's version of of JavaScript (Mozilla Rhino) is not providing access to the built-in objects (Math, Boolean, Array, etc.). We are working to fix this.
In the meantime there are a couple of steps to take to try to work around this. The first is to find the definitions for js these objects, and the second is to import/embed them into the Javascript files you are using. I'd love to have immediate solutions, but will instead settle on telling you we will work on this. Any hints from Javascripters on the forum? When you say "I can use Math.sin(x) directly from the library.", do you mean in a browser? I'm just fishing for hints to try to figure out some workarounds. Sorry it too so long to arrive at this conclusion. -- Scott On Apr 16, 3:54 pm, mwz <[email protected]> wrote: > Scott, > > I guess I did not make myself clear.
