| Still no answer...
|
| Anyway, I found out some more - I notice that the client validation
function
| (ValidateName) *is* triggered when I enter a value in the text box (that
is
| supposed to be validated), but it is *not* triggered when the text box is
| empty. (I found out by putting alerts.)
|
| I also found that no matter what I do, the server validation function
| (ValidateNameOnServer) is not being fired. I removed all the client
| validation, but it made no difference - it still didnt fire.
|
| I'd really, really appreciate it if someone could help. I'm sure it's
| something fairly straightforward.
