Hi All!
I Have a Form with a PageFrame With 4 pages.
In the init of pageframe i add a container on the fly with content of my page.
The uienables events of the objects in the added container are fired. This behavior is in contrast with the help and differ from vfp8.

The below code trace some events creating the form described above, and the resulkt differs from vfp8 and vfp9, in vfp8 i have correctly:

MyPageFrame Init
MyForm Init

In Vfp9 i have

MyPageFrame Init
Text UiEnabled (with lEnabled = .T.)
MyForm Init

Local oForm
Activate Screen
clear
oForm = CreateObject('MyForm')
oForm.Show(1)
Return

Define Class MyForm As Form
	Add Object PF As MyPageFrame
	Autocenter = .T. && Only for read the background screen
	Function Init()
		Activate Screen
		? 'MyForm Init'
	EndFunc
	FUNCTION PF.Init()
		Activate Screen
		? 'MyPageFrame Init'
		This.Page4.AddObject('CntGrid', 'MyCnt')
	EndFunc
EndDefine

Define Class MyPageFrame As PageFrame
	Add Object Page1 As Page
	Add Object Page2 As Page
	Add Object Page3 As Page
	Add Object Page4 As Page
EndDef

Define Class MyCnt As container
	ADD Object Text As MyText
	Visible = .T.  && Deleting this line the uienable don't fire during the init of pageframe
EndDef

Define Class MyText As TextBox
	Function UiEnable(lEnable)
		If lEnable
			Activate Screen
			? 'Text UiEnable'
		EndIf
	ENDFUNC
	
ENDDEFINE
