CasperJS的填充方法

检查我的脚本的一部分：

casper.then(function(){ 
    if(this.exists('#msisdn')){ 
     this.echo('ok found'); 
     **this.test.assertExists('form[id="internetPlus"]', 'form is found'); 
     this.fill('form[id="internetPlus"]', { 
      'numero': 'xxxxxxxx' 
     },true);** 
     this.click('#button');

而且我得到了这个错误：因为断言结果是正常

**PASS form is found** 
[info] [remote] attempting to fetch form element from selector: 
'form[id="internetPlus"]' 
**[error] [remote] TypeError: 'undefined' is not an object (evaluating 
'field.getAttribute') 
FAIL CasperError: Unable to fill form 
# type: uncaughtError 
# error: "CasperError: Unable to fill form" 
CasperError: Unable to fill form            
    /home/soufyan/workspace/casperjs:524 in fill 
    /home/soufyan/workspace/casperjs/kkostoreHomeTest.js:45 
    /home/soufyan/workspace/casperjs:909 in runStep 
    /home/soufyan/workspace/casperjs:252 in checkStep**

我不明白为什么我不能填写表格。

刚刚添加适当的异常抛出时，这种错误发生https://github.com/n1k0/casperjs/commit/78683e2cbf78c9993eadce82f3ed4c10962497c1 – NiKo 2012-10-14 12:44:49
