getlines() not returning

[Kirko]

The functions getlines() and getlinecount() are returning nothing but when I do something else like gettext() it returns correctly.
This is all in a for loop when displaying messages

PHP Code:

echo(("Message_"@temp.i).getlines());
echo(("Message_"@temp.i).getlinecount());
echo(("Message_"@temp.i).gettext());//only one to work 


Another thing I tried to do

PHP Code:

this.trueSize = thiso.catchevent(this, "onReflow", "onTest"); 


PHP Code:

function onTest(temp.obj, newwidth, newheight){
  echo(temp.obj.getlinecount()); //does echo correctly
  return temp.obj.getlinecount();
} 


but then back in the for loop this just doesnt echo anything

PHP Code:

echo((@"Message_"@temp.i).trueSize); 


What I'm trying to do is get the amount of lines there are in the text control so I can adjust the y position for the next message.
