CreateInsert button problem

Question

Hello all. I have a problem. I have created an adf table based on a view, with 3 entities (3 database tables) with the appropriate 1 to many associations.
I then dragged the CreateInsert button above the table, and then the commit button.
When I run the page and click on the CreateInsert button, nothing happens. It just loads, but never creates an empty row where one could possibly write into the table. I should also state that all of the attributes are updatable I checked the entity that created them and the view and the always button is clicked.
Here is the code for the button
<af:commandToolbarButton actionListener="#{bindings.CreateInsert.execute}"
text="CreateInsert"
disabled="#{!bindings.CreateInsert.enabled}"
id="ctb1"
partialTriggers="t1"/>
I really have no idea why it does not work but am wondering if it has something to do with the view being composed from more than one entity (database table), and therefore it creating rows in 3 tables at the same time. Is this even possible?
If anyone can help I would greatly appreciate it

Answer 1

My entity object did not even have a create method. I saw you can click it in the java tab of the entity, should I do that now, and create it?
Also how do I create a trigger for a database sequence? I have created both trigger and sequence in the database but I do not know how to bind it to the primary key in my table, does it have a partial trigger wizard that I can use?

After I changed my Entity attribute to be DB Sequence and generated a create method, I get a -2 in my attribute field as an automatic value when I click CreateInsert and then when I type in all the values and click Commit, I get this error:
Error: Cannot convert -2 of type class java.lang.String to class oracle.jbo.domain.DBSequence
Cannot convert -2 of type class java.lang.String to class oracle.jbo.domain.DBSequence
Any solution?

After adding the following code at the end of my create method
protected void create(AttributeList attributeList) {
super.create(attributeList);
SequenceImpl seq = new SequenceImpl("OBJEKTI_SEQ", getDBTransaction());
setObjekatId(seq.getSequenceNumber());
I get an error, saying that setObjekatId (Number) cannot invoke setObjekatId (oracle.jbo.domain.DBSequence) in ObjektiImpl
What should I do? Should I even be doing this?
