Unhandled error in icrg 102

Question

I HAVE THE NEXT ERROR 'UNHANDLED ERROR IN ICRG 102' IN ORACLE FORMS 5.0 WHEN I CREATE A RECORD GROUP WITH THE SENTENCE 'select nombres, to_char(ficha) from abogados order by nombres ' where nombres is data type VARCHAR2 and ficha is NUMBER. TOO I GOT IT THE SAME ERROR WHEN I CREATED A PROCEDURE WITH THE NEXT CODE:
PROCEDURE Populate_The_List(list_id VARCHAR2, sql_stat VARCHAR2) IS
group_id RecordGroup;
outcome NUMBER;
BEGIN
--Create temporary record group.
group_id := CREATE_GROUP_FROM_QUERY('List_Elements', sql_stat);
IF ID_NULL(group_id) THEN
MESSAGE('Record Group could not be created in Populate_the_List.');
RAISE FORM_TRIGGER_FAILURE;
END IF;
--Populate record group.
outcome := POPULATE_GROUP(group_id);
IF outcome <> 0 THEN
MESSAGE('Record Group could not be populated in Populate_the_List.');
RAISE FORM_TRIGGER_FAILURE;
END IF;
--Populate list item
POPULATE_LIST(list_id, group_id);
--Destroy the temporary record group to release resources
DELETE_GROUP(group_id);
EXCEPTION
WHEN OTHERS THEN
MESSAGE('Internal error occurred in Populate_the_List.');
RAISE FORM_TRIGGER_FAILURE;
END Populate_the_List;
ANYBODY CAN HELP ME WITH THE SOLUTION

I'm not sure why you're using a WHEN OTHERS exception clause.
Trapping all errors and issuing a rather unhelpful "An error occurred" message is seldom very useful. Allowing any errors you don't specifically want to handle to propagate normally makes debugging much easier.
