I'm having a problem with the dynamic resource pool page. When I click the link to it i get a NullPointerException error.
I'm still able to access the static resources pool page.

What did you mean by CM DB?
I have the same problem like you, I tried restarting CM and MySql CM is using, but the error remains the same.
