SF2.8未定义索引：FormType

Question

我很小，在项目上与Symfony 2.8合作。 我在尝试访问一个我绝对不理解的复杂编辑表单时遇到此错误：

  

注意：未定义索引：\ TKS \ BlogBu​​ndle \ Form \ ArticleEditType

     

堆栈追踪：

     

  
1. 在vendor \ symfony \ symfony \ src \ Symfony \ Component \ Form \ FormRegistry.php中   第103行
        

@trigger_error（sprintf（'通过其字符串名称访问类型“％s”是   自2.8版以来已弃用，将在3.0中删除。使用   完全限定的类型类名“％s”代替。'，$ name，   get_class（$ this-＆gt; types [$ name] - ＆gt; getInnerType（））），E_USER_DEPRECATED）;           }           返回$ this-＆gt; types [$ name];       }       / **

     
  
1. 在ErrorHandler - ＆gt; handleError（'8'，'Undefined index：\ TKS \ BlogBu​​ndle \ Form \ ArticleEditType'，   'C：\ XAMPP \ htdocs中\ tkstrs \厂商\ symfony的\ symfony的\ SRC \的Symfony \元器件\表格\ FormRegistry.php'，   '103'，数组（'name'=＆gt;'\ TKS \ BlogBu​​ndle \ Form \ ArticleEditType'，'type'   =＆GT; object（ArticleEditType），'extension'=＆gt; object（DependencyInjectionExtension）））   vendor \ symfony \ symfony \ src \ Symfony \ Component \ Form \ FormRegistry.php at at   第103行（...）
