What is your experience with JBoss Seam? What problems did you find?

Stumbled upon Jboss Seam I can't beleive what I see.

I jsut read some pdf , explaining Seam features.



1. JSF part is seemingly improved, I found many useful things right out of the box, that I previously coded.

2. Validations through all the system, vertical and horizontal

3. helpful rendering of highlights for validated components.

4. out of the box transaction support(that is not unique to SEAM, but good with all the rest)

5. conversations


That what I only happend to discover.


Now tell me the truth, is it really such good thing as they argue?

What is your real life experience with SEAM?

What is on problem part? What drawbacks and neglects have you noticed?
