Favorite RIFE quote : "Really? I have to do nothing?"

Today on IRC:

Question:
What is the proper place to validate that a form field is numeric? I'm trying to avoid the NumberFormatException when someone types a non-numeric string for a bean property with the double type.

Answer:
It automatically adds a validation error, just by detecting the target type of the bean property, which in this case is numeric.

Amazement:
Really? I have to do nothing?

Made my evening :-)

Heh, got a smile out of me

This should be a tagline when promoting RIFE ;)

Re: Favorite RIFE quote : "Really? I have to do nothing?"

(Sorry for the slightly off topic post)

I have dabbled in Java and, more recently, PHP. I have decided to take one language and learn it in-depth (my interests range from web services, dynamic websites, AI work, desktop apps….you get the idea).

Would you recommend ava? I found Java fairly easy to understand – in some ways the verbosity has helped me. However, it sounds like Python or Ruby might get me up and running faster and would be easier to learn, and can do much of what Java can do. My only concern would be lack of publicly available libraries – making Python perhaps a better alternative?

Thanks,

Justin R
