JSTL not operator question

Howdy,

I'm looking at a jsp that isn't working as I thought it should and I see several cases where a comparison is done that the '!' operator is used as opposed to 'not'. I haven't read that you can use '!' alone so I was wondering if that was a problem with the following lines...


I do know you can use '!=' which I imagine could lead to the confusion with '!'. Am I correct about this?

Regards,

Tim

! as a unary operator and the not keyword are synonymous.

The whitespace is moot. Are you seeing a concrete problem?

Yes but it's difficult to get the data so I was hoping it would be a jsp issue. It looks more like a data issue now. Thanks.

It usually is. Some perverse law says that the problem will always be in the area hardest to debug!
