I use the pre-release version (001493855940942) of AMP. The combination of amp-bind and and amp-list is not working. Every value that I assign to [src] of amp-list end up with this error message wenn amp-state of currentFoo changed:
amp-bind: Expression evaluation error in "'https://localhost:3000' + fooList[currentFoo].bar_endpoint". "https://localhost:3000/api/bar/foo1" is not a valid result for [src].
This seems to be solved by this pull request
