TUniPageControl.OnChangeValue error

[josauro@casasoft.net.br]

Hi

   Same time when exist a TUniPageControl.OnChangeValue, this event is trigged before form create event is finished !!! 
   In this cases if you access other component of form in OnChaveValue, could be that it´s not created, this raise a error because that component is not created yet.
   I think this event is trigged whe pagecontrol is created, but could have others component to be create yet.

 

Some advise about this ?

 

Thanks.

Do you mean the OnChange event instead of OnChangeValue?

[josauro@casasoft.net.br]

Error occurs only on event  OnChangeValue   if I use the same code in OnChange it´s work, but in same case OnChangeValue is trigged if a set   ActivePage := Tabxxx, onChangeValue is trigged not OnChange

Ex: If I use this code this event is trigged before btnDependencia is created, occurs error in btnDependencia  is Nil yet.
But this event is trigged when form is creating... 

 

But if I use this event, its work perfect, but if I set   ActivePage := Tabxxx only OnChangeValue is trigged because this I try to use OnChaveValue

 

Thanks.

Could you create a simple test case to reproduce your situation?
