Some the experiments with different expression (debuglog):

Expression visible in debug log - is the same as it written in front-end.
I leave an effective information only.

The strangest thing - why is not working with the expression ^C:\\$|^D:
$ or ^C:|^D:\ ?
Perhaps all of this requires your attention.

But, if i declare expression at global level:
TWODISCS 1 » ^C:\\$|^D:
$ [Result is TRUE]

it start working:

36948:20101214:222910.168 In DBlld_process_discovery_rule() itemid:24910
36948:20101214:222910.168 Query [txnlev:0] [select hostid,key_,status,filter,snmp_community,snmp_port,snmpv3_securityname,snmpv3_securitylev
36948:20101214:222910.169 Query [txnlev:1] [begin;]
36948:20101214:222910.169 In DBlld_update_items() filter:'{#FSNAME}

:@TWODISCS'
36948:20101214:222910.169 Query [txnlev:1] [select r.name,e.expression,e.expression_type,e.e......
36948:20101214:222910.169 Query [txnlev:1] [select i.itemid,i.description,i.key_,i.lastvalue,i.type,i........
36948:20101214:222910.170 In DBlld_check_record() jp_row:'{"

{#FSNAME}":"A:
"}'
36948:20101214:222910.170 End of DBlld_check_record():FAIL
36948:20101214:222910.171 In DBlld_check_record() jp_row:'{"{#FSNAME}

":"C:
"}'
36948:20101214:222910.171 End of DBlld_check_record():SUCCEED

And what's interesting - in front-end the check text "C:
" (without quotes of course) in my TWODISCS expressions gives the FALSE result !
Any comments?

-----------------------------------

In the last sentence I was wrong. It would be reasonable to test "C:\" text. Then gives the TRUE result.
