[SOLVED] Member textfield not validated in zentyal 2.2

[jvallecillo]

I found a bug using the dhcp module in the last version (I guess 2.2 is the last one).
I added some objects and then members (hosts) to those objects but when I tried to start the dhcp service it didn't start.
I check the server status from a tty and found that the dhcpd.conf file had serveral errors in the hostnames.
It added some members whit names like "-------".
After checking the members names i realize that all of them had "_", so I changed the names and it started fine.
The textfield it's not validated. It did not warn me while adding those members.
Anywhere else to report the bug or download a patch?

Thank you
