Problem with fetching a row after creating a standard form

Question

ORA-02291: integrity constraint (TICKET_DEV.MAILALERTTEXT_MAILALERTTY_FK1) violated - parent key not found
Unable to process row of table MAILALERTTEXT.
I have created a form on the table mailalerttext with the intention of beeing able to put in new mailalert texts. I have taken all the fields of that table:
MAILALERTTEXTID,MAILSUBJECT,MAILCONTENT,APPLICATIECD,MAILALERTTYPEID
and linked it to the mailalerttype table:
MAILALERTTYPEID,OMSCHRIJVING,CODE
I've deleted the field applicatiecd. I've made the mailalerttypeid field a select list using a lov_mailalerttypes, with the following query:
select maty.omschrijving display_value, maty.mailalerttypeid return_value
from mailalerttype maty
order by 1
All the processes are just standard, nothing has been changed to them.
Any ideas what could cause this ? Meanwhile I'll keep trying.

I have created a different form on a similar table with the same comments. dropped the mailalerttype column, and added a mailalerttypecode column.
Inserting now works, with one quirky fact, is that it did one insert, and then it always overwrites the last record. Even if I chose different types, it just changes the last record. So I know now that at least it inserts data, it just doesn't seem to think or make the action, add one count to the sequence and take the next number, which should be 65, which in a way is good if i want to make a difference between the default texts and new ones. So I'm still doing something wrong, or I forgot to do something. Has anyone an idea what ?
Its just that if I can get this to work, then maybe I can find out, how to get it to work on the mailalerttext table and just keep the maillalerttextbis table as backup.
