Regular Expression functions not supported in Interactive report filters ??

Question

I'm using APEX 4.0.2 and I'm trying to create a row filter in an interactive report which uses regexp_instr and regexp_replace functions and I'm getting the message:
Invalid filter expression. regexp_instr
The code runs fine in SQL Workshop
select cytogenetics from z_patient
where regexp_instr(regexp_replace(cytogenetics,'(\,+|\"+|\s)',''),'(^46XX$|^46XY$|^46XX\[..\]$|^46XY\[..\]$)')=1
CYTOGENETICS
"46,XX [20]"
"46,XY[20]"
"46,XX"
"46,XY[20]"
"46,XY[30]"
"46,XY[26]"
"46,XY [33]"
"46,XX[32]
etc...
my filter is just the where clause above i.e.
regexp_instr(regexp_replace(cytogenetics,'(\,+|\"+|\s)',''),'(^46XX$|^46XY$|^46XX\[..\]$|^46XY\[..\]$)')=1
*Are regular expression functions just not supported in interactive report filters?*
thanks in advance

Hi Paul,
regular expression functions are supported in interactive report filters, but it looks like that REGEXP_INSTR hasn't been added as valid command. Only REGEXP_SUBSTR and REGEXP_REPLACE are valid commands for computation expressions and REGEXP_SUBSTR, REGEXP_REPLACE and REGEXP_LIKE for row level filters.
I have filed bug# 12926266 to fix this issue. Sorry for the inconvenience.
