进口聚合物核心 - 脚手架打破google地图 [英] import polymer core-scaffold breaks google maps

问题描述

我有一些工作dart聚合物代码，显示一个谷歌地图上的一些标记。它花了我一段时间，让它们出现，因为它似乎初始化例程有点bit懒，它好像有时没有足够的时间加载地图div，在它试图渲染。无论如何，正如我说的，我得到了工作。现在我想在它周围放置一个核心脚手架，因为他们在许多演示。我添加此行...

 < link rel =importhref =packages / core_elements / core_scaffold。 html> 
  

...整个事情打破了，我得到控制台错误：

 异常：类'GElement'没有实例方法'[]'。 
 
 NoSuchMethodError：method not found：'[]'
接收者：'GElement'的实例
参数：[maps] 
  
 
 
 
我注释掉所有其他行，并将其缩减为一个。
解决方案
（截至今天），使用DartEditor 1.5.8并升级到聚合物0.12.0 
 依赖项：
 polymer：'> = 0.12.0< 0.13.0'
  
这将core_element和paper_element升级到0.1.x（之前为0.0.x）。这看起来是固定的（虽然似乎仍然有问题的图标由ids），我可以运行一个简单的脚手架的例子（ https://github.com/dart-lang/core-elements/blob/master/example/core_scaffold.html ）。你可能想再试一次！
 
I have some working dart polymer code that shows a google map with some markers on it. It took me a while to get those to show up, as it seems the initialization routines are a bit wonky and it's as if sometimes there is not enough time to load the map div before it tries to render. Anyway, as I said I got that working. Now I wanted to put a core-scaffold around it, as they do on many demos. The minute I add this line...
<link rel="import" href="packages/core_elements/core_scaffold.html">
...the whole thing breaks, i get the console error:
Exception: Class 'GElement' has no instance method '[]'.

NoSuchMethodError: method not found: '[]'
Receiver: Instance of 'GElement'
Arguments: ["maps"]
I commented out all other lines and reduced it to just that one.
解决方案
(As of today), using DartEditor 1.5.8 and upgrading to polymer 0.12.0
dependencies:
  polymer: '>=0.12.0 <0.13.0'
this upgrades core_element and paper_element to 0.1.x (was 0.0.x before). This now looks fixed (although there seems to be still issues with icon by ids) and I'm able to run a simple scaffold example (https://github.com/dart-lang/core-elements/blob/master/example/core_scaffold.html). you might want to give it another try!
