I have been following some web examples online about creating a CRUD
application in Flex and LCDS (via CF8) that uses the DataGrid to modify and
update a Database. As long as I have data in the database first, the read,
modify/update and delete functionality works. But I want to be able to
Create a new record in the database and the instruction (from the web
example) was:
-------------------------------
Adding and removing items to the database is as trivial as adding a new item
to the ArrayCollection.
ArrayCollection.addItem(new className());
-------------------------------
That got me lost. I understand the class stuff a little and understand the
structure of the class, but I can't seem to be able to figure out how to
create the correct function that will add records to the database from the
editable grid or from a form. I have done some research on the
<datagrid.addItem> command, and tried it and it will add new information to
the datagrid from the form, but when I attempt to update the database with
the <DataServiceID.commit() command I get the following error:
RPC Fault faultString="Error during create: The BEAN argument passed to the
create function is not of type webexample.cfcs.contacts." faultCode="null"
faultDetail="null"]

My question are:
1) What is the above error about?
2) How do I add a new record to my Flex/CF database via the editable
dataGrid?
3) How do I add a new record to my Flex/CF database via a form?
Thanks in advance.
