Handling oracle forms errors (frm-nnnnn) locally

Question

is there a way to handle an oracle form error (e.g. frm-40508) locally in a way similar to handle oracle database errors.
e.g.
procedure insert_something is
insert_error exception;
pragma exception_init(insert_error,-40508);
begin
:c1.a := 1;
:c1.b := 2;
commit_form;
exception
when insert_error then
<handle insert error on c1 block>;
end;

Answer 1

by locally i mean within the pl/sql block that will have raised the error.
an example i encoutnered recently, but by no means the only occasion i have wished such things:
function mseRecStatus returnvarchar2 is
rtnChar varchar2(32);
begin
rtnChar := get_record_property(mouseRec,mouseBlock,status);
return rtnChar;
end;
This is called from a pre-pop-menu trigger. mouseRec and block are calculated previously. A right-click on a record item below the last record raises error frm-40741 (unable to locate record on block). it would be nice to be able to do something like the following without incolving an on-error trigger:
function mseRecStatus returnvarchar2 is
rtnChar varchar2(32);
non_record_clicked exception;
pragma exception_init(non_record_clicked,-40741);
begin
rtnChar := get_record_property(mouseRec,mouseBlock,status);
return rtnChar;
exception
when non_record_clicked then
return null;
end;
