QuickForm_controller setDefaults() not working as expected in Firefox 2.x

[basic0]

$meds = preg_replace('/\n/', ', ', $pt->getValue("medications"));
$controller->setDefaults(array('medication' => $meds));

 

$pt->getValue("medications")

returns a block of text like "Tylenol\nAdvil\nAsprin" from the MySQL table.

 

$controller-setDefaults(...)

calls a method from PEAR::QuickForm_controller to set default values on form elements, in this case, fill the "medication" text field with "Tylenol, Advil, Asprin". This works in IE6 and Firefox 3 beta3 fine, but in Firefox 2 the field is populated with only the first item ("Tylenol"). The the first comma and everything after it are truncated.

 

Is this a bug in Firefox 2.x? Is there any way to work around it?

A co-worker reports that it's not working properly in Safari as well.
