Feedback is down for me, so I’m posting this here (then again the forum usually goes down for me half the time too so hopefully this goes through.)
When you set the Cue Text of a text field to something with an apostrophe it is not being properly escaped like it does when I set its value. This throws a javascript exception.
Xojo.controls['KIGfZrgM'].setValue("Adam\\'s Choice");
Xojo.controls['KIGfZrgM'].field().setAttribute('placeholder','Adam's Choice');
