Ran into an interesting bug the other week. I was using DrawSVG to make an element follow an SVG path (technically a polyline), and Morph SVG's pathDataToBezier feature to grab and convert the polyline to path data.


I found that if I named my polyline with a specific naming convention, MorphSVG broke. The ID name I used was path_1_1_1 and for some reason the specific sequence of a repeated underscore and a number broke the plugin.


The console log reports "ERROR: malformed path data" but the path is fine; it's the _#_#_# name that breaks things.


Please see attached Codepen for a demo.


Changing my ID name fixed everything but it took a few hours of QA (and baffled coworkers) to resolve. Since I didn't see any online reports of this issue, I figured I'd post here to bring attention to it.

Thanks for the heads up gmullinix, I'll be passing this over the the overlords, someone will come by with an official comment/update asap.

Ah, very interesting. Yeah, the issue was that there's some logic in there to sense if the string you're passing in is actually path data (like "M0,0 C3,5...") or selector text. I assumed if there were 3 or more numbers in the string, it's likely path data. But obviously in your case you've got selector text with 3 numbers in it. I've added some extra logic to better sense this type of condition, and you can test it on codepen using this URL for the plugin: https://s3-us-west-2.amazonaws.com/s.cdpn.io/16327/MorphSVGPlugin.min.js


Let me know if that works for you and I'll add it to the official zips. 


Sorry about the extra debugging hassle. Thanks for reporting this.

I've said it many times before and I'll say it again. What a world it would be if other companies responded to requests and bugs as well as GreenSock. A small bug is reported and literally fixed the same day.

Apologies for not replying sooner, I was on Christmas break. Looks like the updated MorphSVG code is working perfectly in my Codepen now. Thank you so much for such a quick fix!
