[Solved]Phantom component: can't compile or find it till put new one and delete.

[Gald]

Hello!

Sometimes things like these happen (first time with a TFrame) to me, but i can't reproduce them every time.

I just add a new Frame, with a ToggleBox and them remove it and his empty OnChange event.

The following project shows a warning when it is opened and there is only one way to solve it:

Place a new ToggleBox on the Form and delete it.

Is this a Known Issue?

Solved Edit: Thanks for your replies!

It's here: unit1.lfm

Code: Pascal  [Select][+][-]

1. object Form1: TForm1
2.   Left = 421
3.   Height = 358
4.   Top = 72
5.   Width = 460
6.   Caption = 'Form1'
7.   ClientHeight = 358
8.   ClientWidth = 460
9.   LCLVersion = '2.0.10.0'
10.   inline Frame1_1: TFrame1
11.     Left = 32
12.     Top = 40
13.     DesignLeft = 986
14.     DesignTop = 180
15.     inherited ToggleBox1: TToggleBox
16.       OnChange = ToggleBox1Change
17.     end
18.   end
19.   object Button1: TButton
20.     Left = 262
21.     Height = 25
22.     Top = 17
23.     Width = 75
24.     Caption = 'Button1'
25.     TabOrder = 1
26.   end
27. end

inherited ToggleBox1: TToggleBox
OnChange = ToggleBox1Change

that could happen when renaming of items manually, the lfm still has the other name but your class has your new name..

your new stuff no longer gets the events properly assigned because there is like you say, one that has been created in the background of a different name.

You are only allowed to modify property of the frame components, but you cannot delete them - that's probably your problem.
Since you cannot distinguish components on the frame from components added separately the work with frames can very easily become very frustrating.

Whenever I use frames I only insert them at runtime so that these issues cannot occur. The must prominent application using Frames, the Lazarus IDE, does the same, and it is very successful this way.
