Why JD is trying to insert fields not selected?

Question

Hi,
My table has a default value for a column which is not null.
(sysdate for the record creation date).
When I insert a record through SQLPlus without selecting this
column, this columns gets populated with the sysdate. The same
works with Forms 4.5 also.
But when I do the same thing with JDeveloper, the database is
throwing back an error ORA-01400 Null cannot be inserted in to
the database.
The Query statement in the error (BEGIN INSERT...) shows all the
fields in the table, though I haven't chosen the created date
field. (nor a couple of other fields). Why JD is trying to
insert values to the fields that are not there in the query and
not selectd.
Now what do I do with this??
Can u tell me whether this JDeveloper tool is meant for
developing serious applications.

Hi,
Bug for sure!. Because this tool is full of them! What I would
like to know is the possibility of getting a patch. Is there any
plan?
One more thing. I think I have understood what is happening in
this situation. Irrespective of what columns I select in the
query, the entire metadata about the table comes and sits in the
xml file. In my specific case, I tried to delete the attribute
for created date from the xml file. Still it was trying to insert
the value. Later, I found the notnull constraint in the xml file
for this column. When I deleted that attribute also, it worked
properly. I suspect that the insert statement is created by
parsing the xml file. In that case the bug is not in IB data
access layer. It is in creating the xml file itself.
Hope u can throw more light in to this.
