there is a Master-Detail page (Master is Form like and Detail is Interactive Grid) , after save it is not showing data in grid properly. i knew there is something wrong from me. IG contains a column of type Popup LOV to select Item(s), some time it shows data and some times not, some times repeat Item for all rows etc.
i checked in Debug view → Path Info → show , this contains various entries including code to fill IG which also has code for Popup LOV as mentioned above, but after this code it also contains a line "APX$LOV3" where "APX$LOV3"."ITEM_CODE"(+) = d."RFL_ITEM" , RFL_ITEM is a column in this IG and this is of type Popup LOV, highlighted code below is from List of Values created in Shared Components because i want to use Additional Outputs to set some column values, this List of Values is used to fill Popup LOV and there is no other Select List or Popup LOV in this IG. i failed yet to understand what i am missing or doing wrong? please help. ( i can't create it on apex.oracle.com )

regards
