i am using apex 4.2.2 against oracle database 11g on windows 7.
i noticed that CASCADING LOV is not exists for MASTER DETAILS'S (DETAIL BLOCK) items.
suppose, i have master table DEPT and detail table EMP.
i create a page in apex a MASTER DETAIL page.
if i change the master item to a list item then CASCADING option is available.
but if i change the detail's item to a list item then CASCADING is not availaable.
although i am failed to implement in my schema,
but the example you provide seems correct.
this is my problem, i am not understanding it properly.
so i am marking the thread as correct.
but if you find a proper and default solution for this problem, kindly update me.
i am wonder why not apex 4.2.2 has this thing by default?
it is there, but only for html type regions items.
for the detail block, the CASCADING option is not available.
