Summary0013676: Problem with visual form inheritance for form contains frame.
DescriptionSteps to reproduce:

1. Create a form Form1
2. Create a frame Frame1 contains a button
3. Place Frame1 onto Form1
4. Create form Form2 descended from Form1 through File -> New .. ->
Inherited Items
5. Change something on Form2 like repositioning the frame.

Compile and run, when Form2 shows up an error message will be poped
up: Project raised exception class "EComponentError" with message:
Duplicate name: A Component named "Frame1_1" already exists.

The problem lies in the .lfm file which generated as follows:

inherited Form2: TForm2
 Left = 452
 Top = 67
 Caption = 'Form2'
 inline Frame1_1: TFrame1 ==> HERE IS THE BUG
   Left = 48
   Top = 96
   Visible = True
   inherited Button1: TButton

if I change "inline Frame1_1: TFrame1" to "inherited Frame1_1:
TFrame1" everything goes well. However, there are still some problems:

1. I can't display the .lfm file as Form, lazarus complains class
TFrame1 is not found. Manually adding Frame1 to uses clause of
unit2.pas solves the problem.

2. As soon you change anything in Form2, the wrong "inline Frame1_1:
TFrame1" always comes back again.
TagsNo tags attached.

Probably fpc 2.5.1 is required at the moment.

Please test and close if ok.
