=If you don't want this, use public fields insteads of 
=properties.

It's nuts. What's it supposed to protect?
It just makes simple things hard work without protecting anything.

Hello,

I just make a new svn update and i've a little problem:

using:
Printer.Canvas.TextStyle.Alignment=taRightJustify;
return this error:
cheques.pas(210,35) Error: Argument can't be assigned to

Did something change or is it a bug ?



This is not a bug. It is caused by a change in fpc. Assignments to 
fields of structured properties are not allowed anymore (since r7250). 
e.g.: property prop : trec read frec; instance.prop.a:=5;
  

I hope this will be optional at least



If you don't want this, use public fields insteads of properties.

Seems like you have to introduce more properties in the class or work 
with tmpvars in the code:

tmp:=instance.prop;
tmp.a:=5;
instance.prop:=tmp;



Hi,

I'm just curious why this was changed.  Was it to promote better coding 
practices or a more practical reason?


Again, just curious.

If your property is declared as:

property MyProp: TMyRec read GetMyRec write FMyRec;

then
  instance.MyProp.B := 5;
writeln(instance.MyProp.B); would not write 5.

Yes, unfortunately the compiler (2.3.1) doesn't allow this anymore
don't know if this will be merged to 2.1.x maybe it is already (?),
you will have to use a temporal TTextStyle variable, something like
this:
var
  T: TTextStyle;
begin
  etc.
  T := Printer.Canvas.TextStyle;
  T.Alignment := taRightJustify;
  Printer.Canvas.TextStyle := T;
  etc.
end; 

I don't have 2.3.1 to test, hope it works;
