More multiline problems

This public application I just published, "Multiline Test", exhibits the behavior previously noted by ghennessy, but on a more basic level:

The application consists only of one form with one multiline field. The form on load event attempts to set the multiline field to this:

"foo
bar"

but the presence of the linefeed in the text is preventing the form from rendering at all.

This is a new bug, the above application construct used to work fine until very recently.

Thanks for any assistance.

Regards,

Pete
