Set external lov dynamically

Question

Dear OAF pioneers,
I have the following :
1. LOVAM (AM)
2. 2 external lov LOV1 & LOV2 in LOVAM
VO1 for LOV1
select meaning, lookup_code
from fnd_lookup_values
where lookup_type = 'XXHR_MISSION_TYPES'
VO2 for LOV2
select meaning , lookup_code , substr(lookup_code, 1, 2) type_code_map
from fnd_lookup_values
where lookup_type = 'XXHR_MISSION_CLASSIFICATIONS'
The column 'type_code_map' in VO2 is equivalent to 'lookup_code' in VO1
3. Custom Page with different TRAVELAM
4. Calling the LOV from point no# 2
I need to set the where cluase of LOV2 depending on the LOV1 Value , So when ever the user select from LOV1 a value, the value of LOV2 should be filtered accordingly.
Please help.
Regards...ShoooSh

Answer 1

So if I understand the sequencing...
You click button that sets the value of PROVINCE and CITY.
So the city value is set but it's a cascading lov based on the province..which will change the city value, because it's essentially being re-generated. If the city values in the list are correct (based on the province) then you need to set the value of the city AFTER it has been refreshed.
You'd need to set the item again after the callback has finished.
