Thanks to all of you guys,
I found it, for a reason that I don't know, you have to
issue a REFRESH inmediatly after assigning the new value
to your property, or value, if you don't do it in that
moment it just doesn't work, let me be explicit in what
I was doing, after moving the pointer in the table with
Next,Prev,etc..., I call a method that made some calculations,
set the value of various properties and then after that
do a:
=THISFORM.refresh()
to avoid refreshing more than one time, got it?
but this didn't work, so I needed to include =THISFORM.refresh()
in all my navigations buttons, isn't that weird ?
