Validating values in fields

Hey people.

I'm experiencing problems when validating values in fields
I currently validate whenever I loose focus on a field but the problem is that I display a message box each time the value is incorrect.
So when you go into a new field and the last field had an incorrect value it will loose focus from the new field when the message box pops up and so it validates that field as well.

I tried flagging it when focus is gained (and only then validating it), but it seems to gain focus on the next field before it displays the message box and so reseting the flag.

thanks Dylan.

This is probably a litte advanced for this forum. I'm going to move it to the Swing forum, where you'll probably get a better response.


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
 
It is sorta covered in the JavaRanch Style Guide.
