Comment 3 Jesse Glick 2006-10-17 03:36:11 UTC 
Try to align directoryField and masterProjectField - can't, errors.
Unfortunately I saved the bogus form and now I cannot get back my working form
(it is lost, and Ramon Ramos' Local History module apparently does not save
.form files, only .java).

Could you fix the form editor so that if any assertion errors are thrown while
editing a form (pretty frequent in my experience), the last action is
automatically undone?
Comment 4 Jesse Glick 2006-10-17 03:42:48 UTC 
Was able to get form back by switching to flow layout, switching back to free
design, then moving everything back into place manually.

We do this. Not sure why it did not work in your case. Will try with the
attached form.

Now I'm getting AE only when using the Align Left in Column action, and it is the same AE as in bug 91892.
