By simply activating a onDataChange event for a TDBGrid on a form it
pops up a EReadErrorEReadError
 'Error Reading myDataSource.OnDataChange: Invalid value for
property'.

Does anybody have a clue why this may be happening?

I cannot see this event in my TDBGrid, I am using Lazarus 0.9.31 with
FPC 2.5.1

Sorry, it is into the DataSource event: DBGrid Events > DataSource >
OnDataChange

I can not reproduce the error. Can you be more explicit, please? What
are the components you are using? What platform?

----------------------------------------------------------------------

Sure.

OS Win7
Lazarus Version 0.9.30
FPC 2.4.2
i386-win32

I'm working with a SQLite3 BD < TSQLQuery < TDataSource < TDBGrid

I only need to put a TDBGrid and connect it to a TDataSource and
implement its OnDataChange event to reproduce the error

... The TSQLQuery component connected to a TSQLite3Connection and to a
TSQLTransaction.
