SNMP trap mapping issue

Hi there

I am having trouble with 2 devices and their traps.

I have imported their mibs, and what they send is usefull, but after mapping it, i wanted to set some to informative, other to errors, and use transformations to replace the "sumary" with more usefull info (it comes in the trap, but i have to double click it and scroll).

My issue was originally with one of those devices, but now both have it.

The trap comes with the instance name/event class key containing a dot (.).

Example:

compaq.136034476
hpHttpMgTraps.4

The "hp" ones always had those issues.
The "compaq" one used to come like "sCellEventTrap-0d-35", but now it has changed.

The actual problem is that zenoss does not allow a DOT in those fields, so i can't edit them after maping them. If i do edit them and change those values, the maping no longer works, because it does not match, right

Should zenoss allow for dots in those fields, or is there another solution
