Master - Detail LOV

Question

Is it possible to create two LOVs on the same page. That have master � detail relationship between them?
Something like:
1)     P1_LOV - LOV based on �select dname d, dcode r from dept�
2)     P1_LOV1 - LOV based on �select ename d, ecode r from ename where dcode=:P1_LOV�
When user selects data from 1 LOV � data in second LOV is cleared. After it when user selects 2nd LOV � he can see only records from department selected in the 1st LOV.
Thanks,
Lev

hey lev--
because selecting a value from a popup isn't really an event that's occurring on your opening form page, i'm pretty sure it's difficult to have that page submit via a javascript event call in one of its items. one way to have your form page submit when a user selects a value from the popup would be to code your own popup page that submits the opening page when a value on it is clicked. i showed how to code a custom popup page at...
Popup LOV
...to have that same popup page submit the opening page with a specific value for :REQUEST, you'd take the original passback function i showed there...
function passBack(passVal1, passVal2, passVal3)
opener.document.getElementById("P1_ENAME").value = passVal1;
opener.document.getElementById("P1_JOB").value = passVal2;
opener.document.getElementById("P1_SAL").value = passVal3;
opener.document.getElementById("P1_SAL").focus();
close();
...and throw in the extra two lines to set :REQUEST and submit the page...
function passBack(passVal1, passVal2, passVal3)
opener.document.getElementById("P1_ENAME").value = passVal1;
opener.document.getElementById("P1_JOB").value = passVal2;
opener.document.getElementById("P1_SAL").value = passVal3;
opener.document.getElementById("P1_SAL").focus();
opener.document.wwv_flow.p_request.value = 'myRequestValue';
opener.document.wwv_flow.submit();
close();
...and that would submit your opening form page with a :REQUEST value of "myRequestValue" when a popup value is selected. for the record, we've logged an enhancement request to add this functionality to the product in a future release.
