I've always felt that your conditions 1 and 2 were a crock. I can't
imagine anyone depending on that. I would vote for just changing the
default.

Historically, this was because Flash 5 didn't support automatically
resizable text, and it would have been excruciatingly slow to
compute the width in JavaScript. (We know, because we did
something similar in order to implement editable multiline text.)
However, Flash 6 and higher support resizable text in the display
model.
I propose that we change the text default to resize=true for
OpenLaszlo 4.0, both to remove this gotcha/annoyance, and for
compatibility with HTML.
This is a potentially incompatible change: (1) Code that assumes
that text without an explicit width will stay the same size even
when its content changes, will break. (2) Code that assumes that
<text> fields without any initial content will default to, and
remain at, 100 pixels wide, will also break.
The heavyweight migration strategy would be to handle this in two
stages:
- In OpenLaszlo 3.2, the default stays at resize=false, but resize
becomes a mandatory attribute. This forces developers to specify
whether or not they intend resizing; it also insures that any code
that compiles without warnings in both OpenLaszlo 3.2 and
OpenLaszlo 4.0, will have the same behavior in both versions.
- In OpenLaszlo 4.0, the default changes to resize=true, and resize
again becomes optional.
Or, if the (1) and (2) are rare, we can use a simpler migration
path, and simply change it in 4.0. (In fact, if they're rare, we
might as well change it in 3.2.)
Thoughts?
