Jerry, can you try this again with a current head release.

I have a tracker with two date fields and an integer field.

If I put a valid date in one field and put a real number in
the integer field, an edit exception is raised. The date field
is still properly displayed on the form.

Same when putting the value 10 in my second date field. The first
date field is still ok and no sign of a crash.

If my test above looks valid and you can't reproduce or you are
sufficiently convinced that my test shows the problem is gone
let me know and we can close this.
