SMARTGWT - delete DynamicForm from SectionStackSec

问题:

I have the same problem, that is mentioned here. The problem got missunderstood and I don't have the privileg to comment so I created this question. He wants to delete a DynamicForm out of an SectionStackSection object. my situation is the following: I added some DynamicForm objects to the SectionStackSection by using the setFields(FormItem... fields) method and I also added a Button to delete this FormItem out of the SectionStackSection. The problem's the same. Also Tried DynamicForm.removeFromParent(), but the parent object is null in DynamicForm.

EDIT: That's how my SectionStack is build:

SectionStack
  SectionStackSection
     DynamicForm df1 // added via SectionStackSection.addItem(df1)
       Button btn1 // added via DynamicForm.addChild(btn1)
         ClickHandler ch1
       FormItem[] fiList1 // added via DynamicForm.setFields(fiList1)
     DynamicForm df2 // added via SectionStackSection.addItem(df2)
       Button btn2 // added via DynamicForm.addChild(btn2)
         ClickHandler ch2
       FormItem[] fiList2 // added via DynamicForm.setFields(fiList2)
     // ... some more DynamicForm objects added
     DynamicForm dfX
       Button btnX
         ClickHandler chX
       FormItem[] fiListX
  SectionStackSection
    // ...
  // ...

By pressing btn1 for example, df1 should be deleted. The SectionStackSection should be stil shown.

dynamicForm.getElement().removeFromParent();
