Hi Folks,
I'm in need of some help. I recently downloaded the latest build of the
js-only sdk #3885( before I was using #3502) Using GitHub that places that
last commit around Sep 14 or so for #3502
While starting my app I now get this error:
FormItem.js:667 Uncaught TypeError: Cannot read properties of undefined
(reading 'measuredWidth')
at mx.containers.FormItem.getPreferredLabelWidth (FormItem.js:667)
at mx.containers.Form.calculateLabelWidth (Form.js:252)

It looks like labelObj is undefined because createChildren doesn't get
called before getPreferredLabelWidth
I've compared the stack traces from #3885 and #3502 and very different
paths are being taken. Here are the relevant parts:

Please advise how my code should change with the changes in the latest sdk.
