RegularExpressionValidator bug on firefox

[Dave Weeden]

Hi,

I seem to have found a bug in the regular expression validator under firefox
2.0.0.15 when I use saved form field values. Specifically I have an email
address validator for a text box that uses the expression below.

^\s*([a-zA-Z0-9_-]+\.)*[a-zA-Z0-9_-]+@([a-zA-Z0-9_-]+\.)+[a-zA-Z]{2,4}\s*$

When I first enter an email address such as (e-mail address removed) everything works as
expected. On subsequent visits to the form, when I type the 'a' character
the text box spawns a drop down within which I can select (e-mail address removed) using the
arrow keys and confirm the selection using the enter key.

At that point my red "invalid email" address of the validator comes up
though I can actually submit the form no problem as the data entered should
in fact pass validation and does in fact do so during submission. The
message should not be coming up at all.

Also, strangely enough when I select that saved form value using the mouse
the eror message does not come up.

Could anyone shed any light on this issue?

Thanks,

Dave

I tried adding a CustomValidator to probe what's happening by observing the
value of arguments.Value in the client javascript handler. This showed the
following:

1) Under firefox, the page attempts to valid the partially typed in value
when a saved value is selected via the enter key. i.e. it's trying to
valiate the 'a' and not the entire '(e-mail address removed)' as expected
2) Validation is not attempted when the saved form field is selected with
the mouse (or the keyboard under IE)

Hi Dave,

I think your analysis on the behavior is reasonable. The validation code
should have coded the validation rule differently for enter key and mouse
selection cases (for the autocomplete feature in browser).

for this behavior, I would suggest you post it to the visual studio connect
site (or if any existing issue there, you can also vote on it). Thus, the
dev team can also hear more on this:
